Haloalkanes and Haloarenes Overview

yes sir whatsapp me how are you is your sakshi mam tell me once quickly Tell us through chats what all weather you can here i am not so that we can very quickly Get started with today's session today's our We are going to start the first session At the core, we are completely following NCERT I will squeeze out the whole lot things we're gonna do once i check I take whether I'm live or not yes I am live yes na the voice is coming maam's all good yes hey brother what is the new channel So right now it's just a small channel right? Many of these are created live just like this It took him a little time and some The foundation where I am based on NCERT line by I am going to discuss this line with you The very first chapter in the entire program I have taken with you that is halo alkane Hello Aris I should have started Dilute Solution Electro Kinetics and so on but as much as I know that kids Ko na always have more fear than organic It seems you guys got it from organic I don't know why but there is a fear inside me Regarding organic, that is why first I Thought organic has dealt with your fears a after that whatever is done under control There are remaining chapters, we will discuss them So let me give you a little bit of background about today how will we read the chapter of so I There were so many important lines of NCERT in this As important a line as the entire NCERT Every line of everything was for you I have already read it here, I have underlined it so that it may happen that we are in class or not maximum output in less time which is we He brought as many as NCERT There are examples of as many intakes as There are as many questions as there are texts in the last There is a book question, we will try that We will discuss all the questions look this is all happening now well i ok let me tell you my experience I am talking about my childhood when I was in class 10th Do it or talk about 12th I am from CBSE I have been at the top of my state okay in chemistry in science always Maam has burst it so I will give it to you in my I am telling you from experience, now you You will say ma'am yours is very old fashioned We have talked to you for the last several years Look, board exams are going on The question pattern changes to MCQ one marker comes, two markers come Markers come for I agree question The pattern changes but the crux of the question is It does not change even if you take as many samples as you can I'll pick up the papers and see if your boats are okay yes you will literally get to know it friend All things line by line from NCERT If you have asked me then now we can give two shots with one arrow If anyone is going to hit your target It is a competitive exam in which NCERT base is there now you can be rest assured because Whichever level NC, whichever level The concepts you are being asked about these days In competitive exams he will appear directly If there is influence from NCERT then it is once Neither do we take the name of God, and Let's start our today's session okay So let's start our session This is the foundation NCERT line by line Hello Alcanes and halo reins as many as our neat there are kids who are new kids maybe the first You are reading this from me today on this channel Let me tell you don't give it to Sakshi ma'am hobbies mean a lot to things okay My class is never complete without them. One is to see it in our HiFi chat like this Pink colour hi-fi comes in such hands, right? There is one in pink colour and one in different colour Colored hearts so maam these two things I need these two things You will keep supplying me constantly, right? I will teach you the best I can Whole youtube0 line by line series not yet released You must have seen that today you have read well. If you are going then please hype me once Ok, everything should be hyped up once. baby friend look at me brother i will tell you I am telling you honestly, okay, I am very heartbroken I teach you from friend, okay I am a desi I am a human being, I am a local prisoner, yes, this happened, right? The thing means when you see such pink color in chats Do you look high-fi, right? Doesn't it mean you should look this way? I want brother, he is not coming now, yes when this You can see the Hi-Fi from inside, right? Confidence and motivation increased further so let's start with this we are our ncrt line by line total Mila has I think 70 pages I will show you, let's keep it so total in total 80 pages are there 80 pages we are going to deal with it and the speed is good because those are very basic things yes I am assuming that you understand And if you don't understand, let me explain The name of the chapter is Halo Alkenes and Halos what does arene mean take the value of halo alkane Do you have any hydrocarbons for Example: If you have ch3 ch3 any you have a hydrocarbon If any one of the hydrocarbons By removing hydrogen you would replace it with halogen are that is known as halo alkane then This is all on the first page of NCERT It is written a simple and very sweet thing Let me tell you, this is a halo alkane Inside the halo alkane, we would have a halogen is that is basically attached to a carbon whose Hybridised I attach it to sp3 hybridized carbon. we say hello alkane understood further See if I continue this small This part is given in NCERT, this is for you In NEET and sometimes you have JEE Mains then the child is asked in the paper I thought it was out of syllabus, it came out of There is no such syllabus even in the boards Things are asked in forest marker nowadays look carefully ok look at one more thing If you have come here thinking that I will read this the replacement of hydrogen atom in an aliphatic and aromatic this is time waste in I will not do the entire NCERT for you. If you have marked it after reading then all the issues These are the things I am teaching today After attending NCERT session, you will get I will never pick up NCERT and read it again You will have to answer all the questions we will discuss it in class ok Do not read it again in full detail I read it all up front Look kids, I have drawn these lines in red. It is marked, it is written chlorine containing antibiotic whose name is chlormequat I also had typhoid in my childhood Anyone who has ever suffered from typhoid will know that you take an antibiotic doctor It gives you an antibiotic, right? children know more, then those who The name of the antibiotic given to you is Chlormequat IO ones work well If we don't know then use chlormequat which is effective in curing typhoid fever does it work for me i asked you sometimes If it goes in the papers, you should know We should look ahead and see what our body is saying has it produced iodine containing hormones whose name is thyroxine do you know this It may be that our body itself produces a hormone produces iodine in it whose name is thyroxine deficiency of which causes a disease called goiter if Your body produces more thyroxine It decreases, you get goiter, it You must have heard it in your childhood as well as during GK time He used to teach, further he is saying something synthetic Halogen compounds such as chloroxylenol which is used as an anaesthetic now see You are not asked in the paper to tell chlormequat Ning compound is fine which cures typhoid fever Bladder is useful in curing any cause blah blah blah blah so you have to go somewhere One should get an idea from this that brother this chlormequat You don't have to memorize things for any exam You will not be asked about structures in ok let's see now if Should I move ahead in NCERT if we Moving forward, he said that We classify the halogen ones compounds that make up our organic compounds Which contains halogens and their classification Let's talk about the first classification is on the basis of number of halogen atoms that your How many halogen atoms are there in the compound If you A compound having only one halogen is called mono hello alkane say if your compound if it has two halogens then it is called dihalo alkane They will say that there are three halogen atoms, try this hello alken say now see if a The halogen attached to the aromatic system is the same Halogen is attached, it is called mono halo arine there are two halogens attached to it it is called die halo arine It will be said that three halogen atoms are attached to it try hello arees will say chamka now Many children think that yaar maam is so simple Why are simple things given by NCERT You won't believe that this year JE in mains paper ok now we have given the paper Let's discuss this year's JE Mains paper I have been asked very simple questions, tell me Which of the following is an alike halide then when Such questions can be asked in your JE Mains then you should think in short that this is the same The same question may come in your boards also. Absolutely basic things can come in NEET as well If yours is clear then you can clear any paper you will burst it but only if you stay in the wide area that this comes to me, this comes to me, this comes to me base if you don't know the paper you will I'll come back completely trashed, okay? Now it is saying to keep the basics clear and look ahead We find that alkyne halides alkyne halide or halo alkane is called They say listen carefully suppose a carbon which is sp3 hybridised if you look at it Halogen has been attached, this is called alkyne is What is the halogen attached to the sp3 carbon? he will say it will be called alkyne halide, that is completely correct Now look carefully at the carbon you used If the halogen is added then it is added even by one more R He did not join the group and did not even do a single This is called not being connected to the group what will you say about methyl halide this is non s Methyl halide if look further if there is a carbon which attached to the halogen, it further becomes a carbon One is connected to the chain, which means it is a halogen nor the carbon it is attached to is further away is attached to the same carbon chain, it is called Primary halide means the carbon from which There are two R groups beyond the halogen attached should primary halide listen further which A halogen is attached to a carbon if it has There are two R groups: R-methyl ethyl propyl Anything can happen, this will be called secondary If the carbon to which the halogen is attached is a halide It is further attached to a three carbon chain Having known this, we will say Tersh Halide It is even more important that you know Now what are alike halides All the children will listen to me very carefully. And all the kids will write this thing in the chat Write on the carbon next to the double bond If it is halogen then what will we call it, is it alike? The carbon on either side of the double bond will be called what do you say Alike shone what is written about the double bond The side carbon is called alike i.e., the carbon What should be the halogen attached to the carbon should be sp3 hybridised What is halide, another question came, Assertion The alike halides of the region are those where the carbon on either side of the halogen double bond A few simple questions are coming up you just need to know now look now What will happen, suppose I said this here halogen is connected so brother it is double halogen on the carbon side of the bond If it is connected then what will it be called alike halide It shines, it is clear, now look at the benzylic What is a halide, benzylic or it is important benzylic means look carefully if alike If it is benzylic bean then this is what should be there halogen on the carbon side of the double bond What will it be called if this double bond is alike If it is a part of benzene then what did I say halogen on the carbon side of benzene what would be called benzylic Look at the carbon on the side of benzene What will the halogen be called? Benzylic see ahead If the carbon to which the halogen is attached here is attached to the same r group then it What will be called primary benzylic halide it's shining look ahead suppose it's double it benzene The carbon on the side of benzene is The halogen above is connected to two further r groups now tell me is it benzylic yes so should i say benzylic is A special case of alike bhai hai to double If the carbon on either side of the bond is alike but because that double bond is of benzene it is a part what will you call it benzylic next Look, someone tells me to find out if it's primary it is secondary it is tersh how will you do halogen How many more R is the carbon to which it is attached? is associated with group three that's why it what will the turks say what will the turks say this story has caught everyone's attention so far yes double bonds neighbouring the double bond halogens on the neighbouring carbon are also okay ok very good now listen further Let's continue One is vinylic, vinylic means double What would the halogen on the carbon bond be called Halogens of carbon with vinylic double bonds Look at the halogens on carbon with double bonds What is the halogen on the carbon with the double bond? Halogen on carbon with double bond will be called what would the vinylic shine be called and if that Double bond is a part of benzene they say aryl look this is benzene benzene There is halogen stuck on it, I I will simply say aryl halide, look at this benzene is directly above benzene Halogen is attached, it is called aryl Hello, these days such questions have become very famous oh you will give the bit sat paper okay there Such questions also come that you have to choose quickly. tell me which one of these has to be done which one is benzylic which one is aralia If it is vinylic then you should have this clarity Necessary Let's continue further Nomenclature Literally a question of clature on your boards A simple thing comes and another good thing I will tell you the entire question from NCERT it is picked up okay look at this in front of me I think you know the basic thing, you have to The name should also be included, the common name should also be included So let's say I have three carbon atoms. and here it is br9 from here it will be 1 2 3 its name will be propane is one or not one bromo propane bromo will be pasted next pasted next If it goes then what will be its name One Bromo propane and because there are three carbon atoms In straight chain it will be called en propal Bromide is its common name now It is important to listen carefully to what I said did I paste chlorine here so it All the kids understood that ma'am is too chloro propane is to me 2 chloro propane It is not important for me, you know what It is important to be careful Listening starts at the end of the chain look this is the end of the chain let's start from here a methyl on the second last carbon If there is a group it is called Isopro pile, this group that you see This is what appears to be a 90° angle it looks like this is made up will say the meaning of iso propal iso iso starting from the end of the chain A methyl at the second last carbon is We call it iso because there are three carbon atoms. it is called iso propyl bromide See iso propyl chloride or iso Propyl bromide shines bright, look ahead This is very nice look at this this this now Think for yourself and tell me what you would say to this IU Pack Namein Everyone knows the common name you always get stuck see how you learn do you need to start from the end of the chain I learned how to do it, yes is it the second last Yes, it is carbon so second from the end of the chain one methyl group total on the last carbon how many carbon atoms are there four can I iso propyl bromide bole doon ice iso propal iso butylish what time is orientation today from 300 So I'll try this one at 3:00 Let me wind up the class and then I will tell you 3:00 PM Hum Orientation with Nishant Sir will take youtube2 3 1 3 di bromo benzene tell me Or do you already know these two? Group correspondence with each other [music] This is meta and this is paragraph We will call it meta di bromo benzene what would you say to this, look at this simple you say tri bromo benzene but you Do you know if these 5 positions are written This is called sym tri bromo benzene You might not have noticed it until today the day you appeared in your paper Create a ruckus, you haven't taught me If you haven't taught me then these 1 5 positions It is arranged in a very symmetrical manner say sim tri bromo benzene ahead Look, now we will give it a simple name from here. start numbering let's say 1 2 3 then I know the lowest set of people and rules na to see one pe chloro two pe die two Dimethyl propane is made simple here Two Bromo Propane has become this simple IUPEC Nomenclature It is there in NCERT but such a lovely thing that from here you can clear your neet boards See all the questions of your mains are solved he is saying look carefully he is saying if You stuck two halogens onto one carbon atom Either this is the situation or you have seen someone around you If two halogens are attached to the carbon containing There are two halogens on a carbon atom, this is called are gem dye halide what will gem dye say Halide whose full form is Gemini If the dihalides are adjacent to each other, There are two halogens on carbon, these are called bo What is Vis Di Halide called Vicinal Dye Halide, everyone knew this, it is asked like this Tell me where will gem dye halide be made and vis dye Where will Halide be made? Look ahead, it is important now this is this listen carefully child look at this what did i do it was ch3 ch3 what was this Then what did I do I did two of the thane Hydrogen atoms removed from one carbon But look, I took two hydrogen atoms from here. The atom is taken out and it is called ethyne Cut out two hydrogens from the same carbon Cut out two hydrogens from the same carbon this will be called than then what is made from ethyne so what does this become ethene chloride what does this become Ethyl chloride shone, what did I say the two hydrogens on the same carbon of theene Cut it with scissors and stick halogen on both the places two it will be called ethene chloride see further if you have read this thesis this thesis is from this thesis one hydrogen cut from here one hydrogen cut from here it is called this what is it whenever they will say ethine or ith listen carefully You can remove the hydrogen around it. You will write dichloride here, not here It was written that dichloride is a common method The way to name it is by combining one carbon with two Cut out the hydrogen which forms the species It is called ethyne with two chlorines attached ethyne chloride but if the surrounding If you cut the hydrogen from carbon it will bring ethyne or ethylene and you will write dye Chloride is shining, everyone is fine NCERT will you do intake exercise questions Look, we are doing whatever you say. ok for orientation mains batch or Both Mains and Advance batches of Advance Basically we must have taken all the things We will discuss kids with brother combos If I have to tell you anything then we will tell you all the things there we will discuss it okay ok this is important these are things that you might enjoy if you You know the small things, now see this Aayup One name is very easy, everyone will guess mine It is important for you to get this common name if You got a common name, right? Then your organic improves look there is one assume this is this someone should tell me that this is common tell me the name of IU pack then you will tell me oneto two chloro butane iu pack name ho Look at the common name, do you understand it? that is, starting from the end of the chain There is no methyl at the second last carbon I don't see any L being formed so this is iso it is not iso now pay attention Look, halogens are made up of such carbon which is further linked to two carbon atoms should I call it secondary and how many carbons is it four so can i name it Should I write secondary beauty? t is necessary to study, many children are like this those who go to high-fi coaching institutes It is taught with the assumption that the child knows secondary butylish I was at my tuition teacher's place at that time Do you know which book Pradeep Kar used to follow? that by lighting a book one book would be written There was a very thick book in it, so many questions were asked I used to keep it, my sir is saying let's clear the doubt This is a doubt class, you keep asking questions kid You are racing your hands and asking me what should I think about this I don't even know what is going on Tha Secondary Butylish we are going to put alcoholic drink in it Tell me what product you made This is what did not shine for me secondary Beautilish I have given some things in t, what do they mean So keep clearing NCERT Mains and NEET will be sorted out automatically I understood what everyone had to say, consider it secondary Beautilish one is neo pentyl bromide carefully Listen, this of mine starts from the end of the chain While doing this if two strokes are put on the second last carbon Methyl groups come from the end of the chain Starting at the second last carbon two methyl groups come then the chain continue continue the chain now here How many carbon atoms are there that are stuck on the paper five it is called neo pentile bromide or think of this where there are two such groups You can see where two such groups are visible yes this is called neo but listen to me Take Neo only and minimum five only If it is for carbon atoms then it is for neo It is necessary to add one carbon atom to complete this process. The group is called neo, how many carbons are there five so its name is neo pentile bromide neo pentyl bromide listen next Now many children argue that to see this should also be neo this should also be neo I said no, this group is for Neo. It should be shaped like a swastika It is necessary to have a plus sign here But you can see it here There is a carbon shortage, that's why Neoni now tell me what will we call it, attention Look at the carbon to which the halogen is attached Three carbon atoms are attached to each other, meaning tert How many carbons does Tersh have? Four, hence its name Tersh Beautylish Beautylish look ahead let's see more I said look The carbon with the double bond has halogen on it vinyl chloride say on the side of two double bonds The carbon on which the halogen is present is called the allyl bromide now the paper just says Do the reaction of allyl bromide with aqua tell me the product with k the baby cries I don't know sn1 sn2 while the baby is crying I should not make allyl bromide Allyl bromide means with double bond Bromine is a simple doublet on the adjacent carbon Bromine is added to the carbon on the other side of the bond. will be called allyl bromide now it contains water If you want to put it then remove B and put O, that's it, that's it sn1 reaction he will do further carefully now Look now this happens to me on benzene ch3 what is tolvin called if its Chlorine is in the ortho position, this is called are you ortho chloro tolvin iu pack You get caught in this so I am common I am teaching name maximum teacher name aayu You must have taught me the pack name, I am not teaching it He comes to you I I will teach you, look very cute and beautiful Someone give it to you in writing, benzyl chloride now what do we think benzyl means Ma'am told me about the ones next to the double bond This carbon is called benzylic carbon. Put a note on it, it will be called benzyl chloride benzyl chloride look ahead my I have to write ch2 cl2 name s cl2 I have written said mam ch4 was methane the same as methane Cut the two hydrogens of the carbon with scissors What will become of mithly bhin chaka and chloride Look, isn't it? Or you can also think about this one more One thing about methyl chloride may I tell you what is methylene chloride How will they speak, listen to both of them here of things combos are same carbon You removed two halogens and two hydrogens removed okay two of the same carbon Did you remove the hydrogen or is it now methane? what's inside is the carbon on your side no you don't have carbon in the side There is only one thing possible which we will call Gem Dihalide its name became mithli Chloride Methyl chloride means a compound of methane remove the two hydrogens from the same carbon next You know chcl3 since childhood, chloroform it is bromoform it is carbon tetrachloride this next one is simple so I mean, this whole page had so much in it The only purpose of taking time was that Your competitive exam questions or even if it comes in board exams Do the reaction of allyl bromide and I think this is also a sample paper The question is I can never send you a sample paper Discus I will get it done, I will not let you do ch2 double bund of ch2br Aquasource Get the size done too yes I will do exercise too I will not leave anything behind, examples exercise we'll increase the speed a little bit so that we See if you can cover everything on time I am drawing the structure brother I will tell you I am telling you that today I am as much NCERT as I will teach you You don't need to read NCERT again Complete exercise questions intex questions text book questions which I will try to get everything done because they are behind me look saying draw the structure of all the at structural isomers that have molecular formula c5 h11 b and saying We have to call them primary, secondary and tertiary I said what to do now c5 h11 b This is the NCERT brother, it is good he wrote eight and gave it to me on the paper you would not have given it first what would you do first five carbon atoms in a straight chain I will put all the carbon atoms in The first five carbon atoms in a straight chain Sticking in a straight chain five of five Sticking carbon atoms into straight chains Now Or will you put it on the second one or on the third one? Five carbon atoms in a straight chain in a chain in a straight chain okay five Carbon atoms other than straight chain There is no case, now see what you do next You can see four carbon atoms in a straight chain Put four carbon atoms in a straight chain and put ch3 here what did i do I have four carbon atoms in a straight chain Here, ch3 is a straight chain of four carbon atoms here in ch3 i said brbttcybu6c awesome or this carbon Now stick this and this is carbon bean or is it A doti four stuck on this carbon and this or But if everyone sees this carbon then it will shine 1 Doti 4 pa 6 sa now four carbon atoms The story is over now I said do one thing three carbon atom in straight chain put one this and If you apply the same thing to any carbon atom So this is your exercise question And believe me in your paper even if you don't want it You can give boards, you can give NEET, you can give me this question, these are the questions that come up, this is this JEE Mains previous year question This is the same question I asked from JE All the children were enrolled in PYK Kids with JE will also know the same thing Same question comes in NEET, it is shining Everyone is done, let's memorize the reaction mechanism there is no need to memorize anything the next thing is saying IU Puck Name This is super simple just for you We have to start from where we are why don't you try this ok let's do this one Let's ask how many there are six The example is placing your hand on any one example yes, I will make you do it on some example They keep it, we make it happen, Let's go to the third example to do this Try it and tell me what is the answer Tell yourself what is the answer to this NCERT if you do it properly i promise you are right I am promising myself Your competitive exam is super awesome your neat, mains, everything will come out It will turn out well and the boards will turn out it will come out We think in the boards I don't know how These are the questions from NCERT that come in the boards Look, questions come, I don't want to number them yes I said maam tell me one thing isn't it that start writing number one from here not giving bromine number one number one First we have to give it to him where the double The bond should be the shortest to the double bond I have to give priority, I said what to do what to do what to do then I I used my mind and said ma'am look at this number one this two two this two three this two four give him five give him I have one Longest chain arrived and double in second position there is bond so i said paint to in paint to These should be methylated in the third position three should have methyl in fourth position There is bromine on it, four on it should be bar, so Because bromo B comes first and then methyl That's why it comes in four bromo three methyl paint in shine this question is clear if you If you go then this is how Ayu Peck Norman's You will ask the most important question yet We read that it was this sheet with common names It is super important to ask funny questions okay let's ask a question okay let's go you ask me a question Will you show a write the structures of the The following compound you me this fourth Will you solve the fourth part of this question? Try solving the fourth part of the question. die bromo but to these let's see who all Answer this question in a proper manner will do 1 f di bromo but two in one 2 3 4 one and four pay two bromo is but pay two No, everyone is shocked, let's ask another question Show me, oh, show me one more, until then I will make you come, come and ask the fifth question Try the fifth question and tell me yours. Sit with a notebook, I will prepare all the structures Even if I write it, it will be for your benefit only it doesn't exist until you write it down on paper with pencil No, until then nothing will shine, that blank the page will remain in your mind write this fifth Create the structure of the question yourself Quickly structure the Fifth Question yourself I will make it from here, he is saying one on bromo is four pe secondary beautification put bromo on one put bromo on one and saying four pay secondary beautification should answer now let's see with enough I am asking the questions in class myself ok now its not like i am doing it random yes i saw it myself yesterday which ones There are chances of coming, I am doing what I can they will survive you have to practice ok Now I am free, I can do everything here If I give it to you then you will never revise again As long as the teacher is with us, we don't feel Everything comes to my mind when the teacher is not with me No, then you actually get to know how much If you come, practice a little yourself too You will enjoy it only if you do it, okay this is yours This is a question about the sample paper This is a question about the sample paper This is a good question, ask it in the assertion region these days. Let's take the question, what is this person saying Your bond between carbon and halogen is no this is polar what is this polar Polar means there is polarity in it The delta on carbon is plus the delta on halogen If delta is minus then you will see a dapor Gaya whose direction is positive two negative so he is saying that as You talk about Sasi Bond, talk about Sasi Bond talk about sea bond talk about sea bond The size is increasing, if the size increases then It says that the bond length will keep on increasing Consequentially the Carbon Halogen Bond Length also increases from cf2 you will go down Your size will keep increasing now be careful look this is ch3f ch3cl ch3br ch3i I am teaching NCERT of previous year The question is, look, if you go down the size will increase 1139 1778 193 214 No need to memorize anything Look ahead as the size of the bond The bond will increase and become weak So 452 351 293 234 anything needs to be memorized The most important thing is not the maximum Maximum children of the world wander here I am getting confused, hey ma'am look look If I take out the dapor moment which is equal to q ld ba d isn't it ma'am when we down won't you go ma'am the distance will increase If it increases then the dapor moment should increase, right? When the child feels that he is going down then he will have to go deep down The moment will increase, I will tell you the charge is there a q factor isn't it The dominating factor is carbon and inside fluorine which is delta plus delta The difference of minus is the charge difference It is too much so while going down your bond is less polar and CF bond is more It is polar, okay, I will tell you more, okay Ca bond is more polar compared to C bond look at the finer details okay if you don't see or hear the minute details I talked about CA, CA bond's dapor It's a Moment The dapor moment of the C-C bond is 1.84 1.86 so Sasi bond is more polar than to say bond is here again 1.83 S B Bond Last comes C Bond And there are no more questions in your mains than this. We would neither have come to NEET nor to BIT SET They say out of syllabus is out of syllabus It is not there, it is given in the NCERT table But sometimes no teacher sees NCERT table He does not focus at all, he is saying that he is stuck Go ahead or tell me the reason for not moving ahead Let me see what is in CF bonds I agree there is a problem, Delta plus delta minus charge separation more but distance is less ok ci bond There is less charge separation but distance in If it is more then our best bond It happens, it happens here Sasi Bond Charge separation is also good and so is the distance It is fine that is why CCL bonds are more polar is compared to CF bond this thing is ours Write in your notes and mark with a big star Do it, I give you 100% guarantee that it will appear in your paper I am such minute details which NCERT I am given from here to you If questions are made for competitive exams then Read NCERT properly because it You see the book is cheap and simple and I don't know what agreements you make and Then you go to books by foreign authors When you look at your paper, you will know Friend, the paper was made by NCERT so read the details shone Correct Hi mam please reduce the brightness a bit Child, there is strain on the eyes, isn't it? If I put this in my own eyes I'm stressed because I'm white We generally do not teach on background I mean we try to make sure that the I don't want to teach on background but if I were to If I make it dull then you will feel even more like this You will have to sneak in and see because the line Every line is written and today I am reading this That's why she is not teaching on black background Because I want you all to print it all out and this will continue till further notice It will be useful for NEET students till the end It will be useful for any child who is in the second attempt They are giving them too much work If you are coming then take a print out of these Take it two days before the boards exam The day when chemistry boards are due 2 Go through this entire NCERT once a day before go through whatever things I have It is written extra, there is no question beyond this It seems fine that's why I know what I mean I am also feeling stressed that I have to work for so many hours I will have to teach you in white but yes this is you I am doing this for the people only so that you can If you are unable to take notes properly then do it yourself If you sit down to make notes, you'll be wasting your time It's of no use now be careful look i am talking if you say hello to me preparation of alkane is to be done, whatever this It is written, I will explain it by combining it with the next page First of all you have to take alcohol It must be true that you have drunk a little bit of alcohol, right? You will put it inside the alcohol, it is rotten hclo2 now this is not written in ncert but this is known as lucas reagent what do you say this is called lucas reagent so listen what happens to you now Kids don't have to memorize mechanisms You see, mechanisms are not to be memorized. what is the acid what will the acid give h+ so this is the lone pair of alcohol will he go and attack h+, what will happen oh2 Pay positive but now with carbon oxygen I can't tolerate that I test positive Oxygen left with its loan payer what will happen if it is cut down After that mine comes and attacks what happen will ccl3 comes what happens because of this turbi t so listen if i have primary If I have alcohol then I will have primary carbs Now primary carbo katay will be made it is not stable at all, that is why if With primary alcohol you can make Lucas When you react with a reagent, unless you You will not heat the reaction, no turb tea Secondary turbi arrives in 5 to 10 minutes diddy will give and turd alcohol ho for example you have this alcohol if you its reaction is concentrated If you do it with hclo2 then brother quickly Quickly means the turbi comes very quickly Immediate turbinate comes, this is called there is a test for alcohol that is lucas This is done with the help of reagents and this is what we call method of preparation of alkyne halides is also used Let's do this, this question arises, see this further It is written here that when tursh Alcohol The Reaction is Conducted Simply Shaking Alcohol with Concentrated listen carefully there is a reaction We carry out the reaction of RO alcohol with substance which is called thayo nil Chloride is now available to many children into chloride and sulfuric chloride There is confusion about thio nil chloride meaning socl2 with soc2 now i am only working on ncert I am focusing on dark reactions and I will not talk about anything here and there There is something given in NCERT, I will tell you about it later I will never tell you in detail, don't do anything Take out an h from here Sanika hclo2 went out and what was left was this one stick it on the r it is called rclbeauty101 so2 done hclo2 end React your alcohol with PCL3 watch with pcl3 then listen to what I have to say you talk about pcl3 talk about pb3 pc talk about 5 pb talk about 5 all these These are the lodging agents for the front If you provide halogen then our RO type is Which RO will convert into RC? will convert into aasi listen carefully If you have reaction with PCl3 or PBR3 If this happens then which oxidation does our phosphorus undergo? It is in the state + 3 for the product that will be made Phosphorus is also in +3 oxidation state inside This is your NEET question as well, this is your JE question is also asked when alcohol If it reacts with PCl3 then tell me Phosphorus is present in the product which is manufactured What is the oxidation state of phosphorus The oxidation state does not change here phosphorus goes from +3 to h3 po3 where in phosphorus + 3 now if you have with pcl5 If the reaction is carried out then phosphorus still remains at its + F se will remain in +ph but here phosphoric Acid is not formed here pocl3 is formed Look, pocl3 will be made first so pcl3 type h3 gets converted into po3 but pcl5 is converted into it converts to pocl3 this is shining These are very small minute things now what I'm telling you is my point listen carefully one small line here It is written in NCERT, well understand this also I have come to know that ma'am if there is any reaction to alcohol If it is then tur alcohol reacts the fastest will do then secondary then primary now when you You read NCERT, right? You consider it like a novel. do you read it as if you are reading two or four I might have skipped some lines, but let me tell you The same two or four lines form the questions in the paper. listen look he is saying about phosphorus tri bromide and tri iodide i.e. Pb a3 and P3 are usually generated in situ They are created internally during the reaction are you which is produced in the reaction Mixture by reaction of red phosphorus with Look at Bromine and Iodine Respectfully I have written a small reaction here. If you mix red phosphorus and Do you add bromine or red phosphorus and If you add iodine then the same thing is formed - pbr3 or pi3 and then it gets converted to that There is one in which it is in situ inside The reaction is made inside the mixture These are all our reactions Important reactions for the preparation of Alkyne halide starting from alcohol turbinates of alcohol means na mam fourth Reaction is deleted fourth reaction deleted Brother, now there is NCERT, there is new NCERT, right? which are your NCERT books which are official There is a website which has the same NCERT I have taken some old NCERT from here If you do not take it then whatever is written here is everything there in your NCERT That is why I consider NCERT only. I am teaching you, I understood all these things Now listen to me carefully, this is a small Your one marker question is formed from here What is your one marker question? one marker question look carefully it says if you have reacted with phenol I got it done and suppose I want to make chlorobenzene I can use any reagent here it's of no use to me means if you to make the same reaction hello arin If you do then the whole work becomes useless Why because look, the first thing is oxygen and the carbon bond is inside it has partial double bond character because It has partial double bond character The bond has become so strong that It doesn't even take the name of breaking, I understood that's why we will use different method how to prepare phenol We have to make chlorobenzene from it later on We will discuss it but not with this method because the combination of carbon and oxygen The bond is its partial double bond The character comes, let's make this clear as well Now let's move on to the next topic well first i completed this whole thing which These are our slides, I will save them. I will go so that nothing happens to our If the slides disappear, we are 80 pages long I have completed the 13th page quickly you will keep on reading at a fast speed so that all the Things should get completed now whatever is our next The topic is saying if you have a simple A little bit about hydrocarbons class 11th Let me recap, I am saying that if you have is a simple hydrocarbon and its You did the reaction with chlorine, now paper I may also find sunlight written in it or Heat can also be found written along with chlorine It may also be written 'high temperature' If you find any of these written then whenever chlorine sunlight chlorine heat high temperature But you are getting a reaction, remember it's free Which mechanism will be the radical mechanism will follow free radical mechanism Is there any halogen stuck anywhere? can a halogen stick here a look Your halogen stick can be here more is over No it doesn't happen like this now look at me primary halide formed near and this primary How will halide be made primary free? This secondary halide is formed from radical What will make secondary halide secondary? You already know about free radicals which are secondary Free radicals are more stable because The percentage of secondary halide that is added is If it is more then it will be a minor product This will be my major product but The problem is that whenever you take a photo Do you get chlorination done? You have a lot of Products are made now, Mono Chloro made one and chlorine can stick two Chlorine can stick so this method is very effective It is not considered good, it shone, let's move on Once again this is class 11th work i also let me teach you this is saying if I If you want to make it from alkene then look Let's say I have this situation here double bond ch2 i said if you Tine will be made b will attack here near me This answer has come to this Markov Nikas edition Let us tell you what is Markov Nick Edition The Markov Nick of addition is that whenever An asymmetric reagent, i.e. a plus a pe b both are different whenever a Attacks by asymmetrical reagents On unsymmetrical alkene, this means C doublet If you are getting an attack done on Bond C then There are negative species, they go there On that carbon which has less hydrogen yes Where will the negative species go on which carbon Hydrogen is reduced to Marconi I will never say that rote learning is useless You do it through Rattok Nijsm, well one more I want to tell you something, accept it, right? then we'll come to this suppose I have done this Suppose this was the reaction, same thing to you Same I am reacting now I am reacting to the presence of pox ed in whose presence am I doing the Reaction in the presence of pox id agar pox id means anytime this o bond is visible Now let's see where the mechanism is I require my conditions from myself I will teach you, I will not leave you but whose The work will be done without any mechanism, we will We will skip the mechanism because right now we We are focusing on NCERT if ever pox id this gandhi ji's glasses this oo Bond is visible, these glasses are visible If you ever see O Bond glasses, remember that will be sent to the carbon where the hydrogen To which carbon will we send B if it is more if you send it to that carbon it will come here h will come here ch2 p b this is called Anti Marconic of Edition what will this say is it known as anti marconic edition is it The story shines for everyone now listen this is done good one more little The reaction is given at the bottom, suppose if you will not believe you will believe You will not ask these questions this year JEE Main 2024 Was the question asked in the paper NCERT question is saying that if you Bromine added to the double bond carbon tetra Do you know what is the presence of chloride This happens as the double bond will break on both carbons but br br will come you tell the truth All the JE aspiration candidates have this question it didn't come in the paper it did come ditto same Two same question came in the paper if bromine If put in the presence of ccl4 then the double bond and put a br on each carbon This is the question that stuck out, some of which have appeared in the paper it is not different ok is this question paper I was not there, this is also one of your papers the question is it is a p y why question karo it is saying Identification off look carefully c look at this c two ch3 there is one carbon with two ch3 and this is ch2 ch3 tell me how much possibility is there that how many Structural isomers will form by thinking on their own Answer it's ok to do it it came right yes there was one benzene ch3 was stuck on me, I had to do it on toll lavin Yes, now everything I will get mono-clo products made It means you know what you have to do See how many different ones you have types of carbon are either this one carbon or these two carbons are the same So one product is their carbon These will be formed by removing hydrogen If you remove hydrogen then another product will be formed Then this red colored hydrogen will be formed If you remove 'G' then third product will be formed then this remove the hydrogen of black colour then four If the fourth product is made then there will be four different Products will be made in just one or four just do that much just this question now if your boards what is the problem if it comes in the paper I have to write and this is a simple question isn't it? comes in the marker many times or five The steps in the marker mean five. There are A B CD in the marker If it comes then the question is why you are afraid that it is difficult it is difficult Boards are difficult, nothing is difficult Look ahead, there is our reaction which we speak of halogen exchange reaction listen carefully i have it alkyne chloride now look how beautiful Or does NCERT feel attracted towards this? Look, he writes it here that is it chloride or bromide and this is what you Is there any assertion region in NEET or JE becomes a question whereas here he has written I'm saying if you have alkyne chloride or if you have an alkyne bromide is what you put inside these Get the reaction done, there is nothing in acetone This will happen by attacking from the back side This will create a i and you will have either [music] If you start removing the product The reaction begins to proceed further that's the reason why you are called that if tomorrow you make such a reaction that c takes Take it and inside it you is soluble in cl-1 and if in acetone If it is soluble then it can be leached at least here The principal will not ask me this question I will ask you about your assertion region in boards Ask the same question in two markers on the boards If I take it like this then the question will come that's why Alcaine alkyne from chloride alkyne bromide It is possible to make using an acetone butt vice Versa reaction is not possible ok Vora When will the classes offer end so probably Maybe the offer got extended today and tomorrow I received mails from all the kids, so maybe today You have to check if the offer has been extended it will be okay you need to check it I just this is not checked do start with class 11th to brother, I am class 11th and I am also class 12th I will complete it only if you guys support me say no no no we will just keep teaching We are here, just keep working hard, we will do something If you don't do it then ma'am also won't teach you ok because what am I getting, friend If it works for you after putting in so much effort If you are not able to understand then the foundation of class 11th I have already done Jo Vora classes is the main channel of, where I laid the foundation Many children had done class 11th They benefited from their school exams There was benefit in JEE, there was benefit in NEET That's why Buniyaad Class 12th is for you Start it now, will you follow this? Friend, take my hard work in the right direction If you go then only I will teach you further, otherwise What is the benefit of me coming here to study? ok then i will do something else and record it Should I record something or some DPP kids? is it okay for yes then brother I will I will continue this series and I am very happy I am speaking clearly because you think yes ma'am is coming and teaching me, didn't I do it yesterday before scheduling your class I did all these things myself at first. Nobody else marked everything written I have myself marked that brother this this this This is a line which is very important to me I have to tell the child then I have taken all the NEET exams papers of JE CBSE which will help you There are sample papers and pick them up and see that What questions have come up, that's why I am telling you that brother these questions have come, go through them It's important, okay, okay, let's move on Look, this was the reaction, this is what they call it Halogen exchange reaction A halogen Exchanged with another and got the same reaction Another name for this is called Finkel stein reaction what does finkel stein say Reaction match the following comes your papers This match came in The Following next There is a reaction which we call swats reaction swats reaction too What happens inside halogen exchange? what do we do we have no one alkyne bromide is like bromide Any alkyne is a bromide and I C Pe Fluorine Means Fluoro A Compound If I want to make it then we use it for this are fluorides of metals such as agf2 f2 used c3 used sbf3 used it okay so here we are As many of our different metals There are fluorides which are used to form fluoro alkane is fluoro alkane right? forms fluoroalkanes instead of alkane The name of this reaction is Swerve Reaction. small things come Now let's talk about one more thing, this what is it listen carefully suppose it's okay hello We have learnt how to make alkane, now let's talk about the issue that maam hello arin how to make it so listen carefully i have this benzene okay inside benzene I put chlorine now if I sunlight chlorine There is no reaction in the presence there won't be any reaction but if In this benzene I added chlorine and I am doing a chlorine reaction fecl3 can also be found written, then your It becomes close to you, look carefully it becomes close to you chlorine will come here Now I will tell you the JEE Mains question Recently the paper was conducted so in the paper this the question was asked what was the question the question was that if you took tolwyn in the sunlight In the presence of Dala N and listen whenever What do you have to see if you see sunlight if it is a free radical then can you see it It will form a free radical at the benzylic carbon Then free radical will be formed, here chlorine comes If it goes then what will happen to you benzyl What is the common name of chloride benzyl chloride but if inside this I Dark color in the presence of chlorine ion If the reaction is taking place then the upper carbon It won't make any difference to the carbon above It won't make any difference just because of this or that look at the ortho position or its para You will get halogen in position now this Why did you study this in class 11th This will be called electrophilic aromatic Substitution says it has been a while Its mechanism has stopped for about 5 minutes I will discuss this with you I will get chlorine added inside it in the presence of either ortho halo tolwyn bana ya para hello tolwyn bana now He is saying that your ortho and para hello it happens to tolvin they can easily separate you can due to the difference in there Melting point in their melting point There is a difference, you should separate them SUPER IMPORTANT REACTIONS THESE UR BOARDS This is your sample previous year question Last year's board papers in papers I also had this question what is it saying if If you make it react with iodine The reaction is reversible and the to take it forward right and it requires the presence of oxidant You can get oxidant such as hno3 I have to add hio4 to it OxyDerm What happens to you whenever you Are you reacting with iodine? It will react with iodine to form HI Now HI becomes so unstable that it comes back If he wants to come from behind then we say Bhaiya Don't come back now look like this happened Suppose you have c over c okay and here But we are adding iodine, suppose there is sunlight If I put it in the presence of then one of my I have come near you, we will be able to save ourselves now This is so dangerous that it is unstable Reaction sets us back first What needs to be done is to finish the work of this AI This AI has to me Oxidants hno3 should I put concentrated hno3 or then hio4 is the oxidant, it helps in reducing this h They will put oxidant in it Oxydoben Be happy, this is the end of the story now This next part which I have given is basically us We read in your Amin chapter which we We will discuss on Monday if today and tomorrow and did you attend the day before yesterday's classes properly So the chapter number will come on Monday, Amis I'll tell you from the beginning that this is nothing I have given you less, I have told you from the beginning let's say I have benzene I put concentrated acid in the presence of concentrated sulfuric acid so I will have this nitro benzene Nitro is asked here in the paper When you put ton of benzene in it, the presence of H2O What does a ton of AC do in a very It is a good reducing agent, now this what will reduce reduce no2 will make anline now you will be inside anline Will you put nano2 get it done at 0 to 5°c here in our is formed near benzene on n2+ cl2 cl2 or in the book put cucl2 br2 or in the book cubr2 mer What is the reaction called Sand Meyer Reaction When you do Sand Meyer reaction it is n2 There is a good leaving group, will go here But chloro benzene will come, look here This is a reaction called sand mayor The reaction shined but it doesn't appear in the paper like this In the paper, there are sequential ones which you You tell me, ma'am, don't I know that? It is said that convergence is also of convergence We will practice now, everyone has shined now He is saying that if inside this you can suppose n2 you put tomorrow's k in the sa mine If you put it in simple then n2 will come out here the iodine will come you see i If you add iodine then it will come according to Dyso's rule Whatever the reaction is back to the Amin chapter repeat from I will get the discussion of MAP done, which one will you do I will not do this completely bad thing, do this third part will you answer, you can see it to me I know, but do it honestly so that you answer will shine yesterday same question fab I came in shift one, I have seen in another Chanel they said by chlorine sunlight there will B C S please reply mam I am very I will explain it to you clearly I don't know what you are explaining if you put chlorine sunlight inside it Do anything for free radical substitution it happens ch2pas comes and this is the end of the story there is nothing after this if you have done this Chlorine added inside in the presence of ions If anyone says anything then it is NCERT So whatever it is, it is NTL or JE Whether it is NEET, these two majors will accept it Products must be sunlight or heat provided so ch2 got stuck here fecl2 If it is given then it will come on S or Ortho or Para He will come on the next paragraph because he is a major Steric weakening is less, it shines Everyone should be happy ma'am how long will the chapter last I look at you, I am teaching myself without stopping I know, for you, for me, for all of us Time is very valuable for you You have gone, just wait and watch, we will do it quickly yes, it is there, I am not stopping anywhere If you say so, I'll increase the speed a little more. yes I can increase the speed if you want but I feel like if you do it friend then do it like this If you don't have to come and watch the lecture again, try it Let's wind up by quarter past two I will try my best, at the most it will be three o'clock I will not teach you more than this, okay? will wind up as quickly as possible so that Maximum output should be achieved so that let's talk about liberation brother Sir, it was visible as soon as I looked but on the oxide In oxide maam said that B minus It will go where there is more hydrogen Look, send this hydrogen over to Bar Send it here, the answer has arrived, more paper than this I don't come, let's do this now, let's ask this question This question comes in do one marker This question will come in the marker, answer it quickly And don't do this, it's cheap, isn't it? I'll tell you to do what I I am marking it, keep doing that It is important that you do whatever I mark. Go, take this reaction, it's super important Recognize this is JEE Mains reaction right now It has been asked now that 2024 will be declared, so all the NEET students You are kids so be happy for JE paper I have been asked this reaction so you should do it Come on, you'll put the purple ones on which I put the purple I have marked all those things, you will do them one friend You will ask five questions which will be marked in purple hey do it quickly two quickly quickly he is saying quickly that it is sulphuric acid not used during the reaction of alcohol Vid K is saying suppose if you have consumed alcohol you want to do reaction with h2so 4 why won't you use it, think and tell me why you will not do one marker question it is quickly quickly quickly quickly Quick The answer has come, hey brothers, what did the people say expected it, people expected it that this is the best with h2so 4 first it will make h this is h right it will give h+ so This RO will go and attack h+ to become first we want r2 to be positive then come to a minus and then this but will attack to form aa it should be it was but you know this h2so 4 This is a very strong oxidant, this is it will give oxido to iodine So brother when HI is not there then there will be a reaction where from and I am telling you again I will definitely look for such questions in the paper this time. will meet anyone whether it is your neat or JE whether your bit is set or not Your board exams should have similar questions come on shine because h2so 4 a It is a strong oxidant that When there is no reaction left in Oxidol It won't happen, come on, try this and tell me, try this and tell me so me too If you do this and tell me, I will also believe it I will go quickly, tell me first of all quickly Tell me this is one, I should remove the numbering a little I will give it to you because I can't see it, yes do it now Take it so that you can see me too 2 3 4 2 do this make it two make it three make it four If you make it six then first of all make it two, A sap How will you do bromine sunlight maam in two It was said that free radicals will become free in sunlight Radical means the carbon on the side of benzene Pe bromine will come aa gaya to ka answer aa Everyone's answer to '2' should come benzene the carbon next to it should come on the B Answer three. Answer three quickly. Ma'am of three said that if we apply heat then firstly oh2 will become positive then carbo keto in Here, this one will react directly otherwise remove o and put s to get the answer. I have come, apply it to O and then remove O and put it on S. put s, the answer of the question is given ahead Look, ma'am said HI HI, ma'am said I told you to first make some carbohydrate cuts carbo cut carbo cut will make only that If tert is formed then the carbon on which CH3 is present will be paste the carbon copy do this here I will agree, do this last one I will agree, why don't you chat soon? Yes, do the last one and I will agree Quickly quickly quickly quickly the last answer Give me all these questions, brother. It will come in the paper, it will not come out There is no need to do any sample paper after that Nothing more than this will appear in the paper ma'am had said that bromine is present in the presence of sunlight If you are putting it then maam had taught me to do double bund If a free radical is formed near anything Do it, BR will come here, you can do whatever you want Bir will come here this is NCERT's index These are super important questions, aren't they? Maximum questions arise from here Let's make it in your paper, come on one now I come to the next topic, the name of the topic is physical properties these physical properties topic is so good ok that your board The right support is necessary for the exams It is also very important for your JE and NEET If yes then I will teach you a little about physical properties First, let me give you a few things I have to teach them well, I want to know Let's see who is saying this to us If alkynes are present then alkynes are colourless It is colorless if it is pure But if I talk about bromide and iodide When we shine light inside them They import a lot of color A simple fact is written about the issue Look at the thing, I have underlined it in red I have done this, it is important, I am saying it whether You are talking about methyl chloride, methyl Let's talk about bromide and ethyl chloride Talk about these things which are light hearted In the beginning, these members are light Because they are light, they are gases as it goes down at room temperature Your mass will keep increasing as your mass increases Side-by-Side Vander Waal Forces of Attraction Vendor wall forces of attraction will increase Their melting point increases due to the increase in will increase and then these solids and liquids Look higher they keep converting into The members are either liquid or They are solid, what happens next, be careful See, what do you think about these carbon and halogens? It is visible that ma'am there is a If it is Dapor then what is the other carbon and halogen There is dapor inside them too so what do you see will give that the doper between the two molecules Dapor interaction is visible Intermolecular forces are one and the other Dapor interaction is Vander Waals The size increases as you go down If the size increases then vendor wall forces will increase of attraction will increase dapor dapor interactions will increase because of which that is Why the biological effect of chloride bromide and iodides are considered higher than those of hydrocarbons mean if I have a is a hydrocarbon and is an alkyne halide Because alkyne halide is polar inside it dapor is dapor dapor interaction is mass is higher due to the Wonderwall forces off attraction is more that's why hello alkane has higher melting point Compare to Hydrocarbon, look ahead brother Sir, this bulb is as much as you want It is very important for you to make it shiny You take it lightly, I am a teacher Saying yes to your elder sister as a mentor I would like this is very important from here Questions arise, listen he is saying the same thing Alkyne Group The Basics of Alkyne Halide Decrease in the order, write this in big letters Write it down, it will come in the paper if I become biological what should I talk about R has more biological then is r b then is r s then is ra now many The kids will think that you just taught me ma'am It was said that Dapor was more dangerous in the case of chlorine. It happens that two factors are working here One is the mass due to Vander Waal forces And the size will come and the other one is your Dapor Dapor interaction in this case Joe Vander Wall The forces of attraction are so overpowering I would have done that Dapor Dapor has no value is given because as the size goes down The vendor forces are growing bigger Attraction will increase and mass will increase because of so r i r i will stick to each other That is why RI has more biologicals, see R I RBR R CL RF this is because The increase in mass and the size of halogens Atom Magnitude Wall Forces of Interaction Increase this same question in the paper comes and you get confused and say It is out of syllabus, I don't know which foreign language The author's book had given the name of some foreign author I have given the book in simple NCERT which Your teachers forget to teach These are important things, look ahead 30 30 Jan came in JE paper in June also I am telling this in JE paper also Today you will study NCERT, it is fine There are also JE aspirants and the children with NEET share it with them because they already know It is not that we have launched this new channel like NEET and if it is opened for boards then all our JEE and NEET are exam based on NCERT method I promise you I have read it hmm you will make a mess of you in the paper There is no need to read books by foreign authors If you have just read NCERT properly then I give it You this word that brother you do well in the paper Look ahead, there is one more thing written, look at it So here I have four carbon atoms. there are four carbon atoms b there are four carbon atoms the atom is here you can see that All the chains are isomers of each other isomers as branching increases Your surface area is decreasing your surface area would be less what is the region going as Branching will increase and surface area will decrease surface area is less then vendor wall forces of Interaction less van der Wall forces of Due to less interaction, bowling points will decrease go yes, I understood this also brother, super super super It is awesome in big institutes you are not told this while Things have been given carefully in NCERT listen i have benzene i have benzene two chlorine stick ortho two chlorine Paste two chlorines on meta paste two chlorines on para with respect to each other is right first I will tell you the story of Baling Point hmm okay first of all we will go to bowling point Let's discuss the story, watch carefully You can see that ma'am look at everyone's molars The mass is the same. The molecular mass is the same for all. But the polarity is different in everyone look here above plus to minus plus to minus So this is non polar dapor moment zero it should be here it's going here The overall Dapor moment is going on here it will come here it is going here it will go here The overall Dapor moment is zero and will come here That means I should talk about Dapor. I should talk about Dapor. If I do it like this then it is ortho meta para dapor I know it will happen under √ u1 s + mu2 s + 212 k theta here k is 60 here k If it is 120 then did your Dpol shine so much? Ortho is the highest, then meta Para ka para ka has zero dappor moment Further if I talk about close packing, a Tell me like it's completely symmetrical So do you know all the paragraphs? would like to come closer to each other I try to cling on to you no matter how much They must be so close to each other can stick, now you understand what is solid If I talk about the melting point Which is melt and which is solid Close packing is necessary because para Sticking so tightly to each other can the close packing remain so good so if I talk about the melting point When I talk you will see the paragraph Para has the highest melting point Why did the melting point become higher because There is close packing inside it, then the story is the same The damper moment inside the helix is ​​high and There is less dip moment in the meta so drink it m pum pum pum it happens na pum pum those kids They play with him, it's fine if he's so fluffy they are not made of thread they make pum pum pum pum pum to melting point para ka who has more ortho why because there is close packing inside it now if I talk I do it baby, my friend boils the bowling point you do the liquid inside the liquid Someone is yours, so what do you say Close packing is so much more powerful There is no close packing inside the liquid It is not so powerful that is why it is in liquid If the melting point of ortho is more then Look, this is it 453 will come again your paragraph will come again and The melting point of meta is approximately equal to It happens but still the paragraph is at the last Comes with meta, there is one, it is called opium, right? I will tell you the way to remember, it is not there These drugs are what you mean by what you use You do it, the world uses opium, right? Opium drug class if you use then you are a gaya pom pom pom meaning para which para wala where will more come if I melt Let me talk about the point, second in the case of solid What is opium? Opium makes everyone shine You must have understood this, it is very important for you Talk about boards or competitive exams talk about it brother there is nothing above this come this is an important thing now if I talk about density and you know this Physical properties are literally asked in JE and physical properties in neet too a lot of questions come up if I let me talk about the density as this chlorine is bromine is iodine is as below The density will increase as you go, see this here two chlorine three chlorine four chlorine As the chlorine number increases Density will increase, nothing is going to be memorized Wherever I taught myself important things I am talking about solubility it has been given in the solubility that this which is yours It is an alkyne halide, it contains too much water I am not soluble they are not very much Soluble in water You say that soluble in water my heart has come no no this doesn't happen like this it doesn't happen they are not very much soluble in Water now look at its region what is inside the water There was so much talk about hydrogen bonding What is inside the water that glows There is extensive hydrogen bonding within Whereas what is inside C-S-Bonding What is Dapor inside Dapor interaction diap dapor interactions if you are taking dapor dapor If you are mixing the interaction in water then now What you will end up with is hydrogen bonding It is over and so much energy is not being released look brother c is giving a bond brother this this All the molecules are in love with each other there is more love when in love If you pick it up and put it in it then it is strong the hydrogen bonding is broken and Strong hydrogen bonding is breaking The bonds that are being formed in return are so These are not good that is why the carbon halogens The compounds are halo alkanes it is not very soluble in water If you were to look at it, the hello alkanes are very Slightly soluble in water the halo alkane molecules break the hydrogen bonds between The water molecule less energy is released When new interactions are set up between Halo alkane and water molecule as they are Not as strong as the original hydrogen bonds so halo alkane is very soluble in water they are not very soluble how ever hello Too much alkane in organic solvent are readily soluble in water because the new interactions that are formed between The Halo Alkene and the Solvent are approximately There is as much strength as the strength was between them earlier, did you understand, brother, if this boy boy isn't it all this is a complete This is a family that loves each other very much This is another family, they too are very close to each other Brother loves, there is a relationship between them will happen when the new interactions There should be more than the old interactions If the new interaction is weak then it is between you I would not want to love only shined ok everyone its done now look carefully you will ask me one question You will show me the third question the second one quickly this second one Ask the question and then come to the chemical reaction yes, solve the second question quickly Do the second question quickly take it and then give me the answer give it quickly quickly quickly quickly tell me this question is saying chloro propane very cute one chloro propane iso Propal Chloride Iso Propal Chloride one chloro butane one chloro butane kah Put them at the boiling point first Tell me who has more boling points tell me quickly this is the most Who learned what? We learned this first Mam which has more number of carbon atoms its mass is more its size is more So it will get the highest bowling point now The number of carbon atoms is same in both of them If it has more branching then it poor then two this will come three will come shining or did not shine shone or did not shine quickly tell me is it clear to everyone is it clear to everyone all is good I am understanding and enjoying it, Can ISC Students Watch This is every child who has NCERT in his paper treats as a base if your If this is the syllabus then brother, any child Watch this session in respect of the Fact: You are a NEET student and you are a JE student yes you are a child of state board CBSE board students should study in ISC board you are a child, prepare yourself for bitset Are you preparing for any exam? are doing it if you I want to learn NCERT, I think it is the best M I am teaching in the best way, watch now If the concept is clear then brother Sir, you should handle the question like this catch how you want catch question assertion The question should come in the region in multi correct Numerical should come in single correct come in the match the following come in The form of the question will change Understand that nothing can change The sooner you understand this the sooner I will have Clarity tomorrow or the day after tomorrow I talked to her, she said I don't know which one I belong to Maharashtra board she was telling me the paper was from my second or third It has started so I said what comes to your mind She said NCERT is there in the paper Maam but we don't read NCERT I said why don't you read our The teachers in school tell us a They make a booklet and give it to him and he says the words just memorize that booklet okay and that's it Just say the same thing and in that time your number will come It means you will get 60, 70, 75 marks easily. Will you bring it if I spit out that booklet He said, okay, tell me how long? Now ma'am is telling you that you will use that booklet to memorize it Suppose I have an exam after four days. If yes then I will start cramming today for three days I will memorize everything and the day after tomorrow I will tell you one thing tell me this is how you are preparing You wasted those three days by memorizing it And your marks are still coming out to be 75 When you study for JE or NEET then You won't say no, I know something No, brother, teach me things from the beginning Study in such a way that if you prepare for the boards now If you are studying for this then it is important to work hard in JE This should be useful in NEET and not just rote learning memorize and learn things later Make him vomit in the paper, it is of no use to him There is no need to cram, I am saying 90 Instead of bringing it, bring 80 in the paper, then It's ok don't memorize it, if you keep on memorizing then it's your own you are shooting yourself in the foot, time is a waste If you are watching Watch is Super Rang then read it you tell me yourself you tell me yourself does it have melting point no o pm po m is this your jee's There is no question, NEET students tell me what This is in your NEET previous year question It is not there, I have checked it myself, it is neat If you have any problem then read the things in this way that at least it means something beneficial Do you want it or not, memorize it and spit it out, tell me get the sample paper done, I asked why are you saying this We will find out what comes in the paper Brother I said if you knew NCERT You will need some sample paper, right? You don't need to know the concept So the process of memorizing four or five questions There is no use of you going after killing me so let's do one thing don't save the file let's keep doing it so that this hand written You will understand these slides of mine very well. It could be useful It's 12:30 now almost 1 o'clock Let's see around how many pages we have Let me go and talk about chemical reactions I am the first chemical reaction that I know Do you understand that it is nucleophilic? substitution reaction what is written here shoot him, let me explain first Kids we're doing a reaction study which is called nucleophilic Look at the substitution reaction, like this carbon and the halogen has a bond what do you have to do a nucleophile nucleophile means Electron rich species, this will come to halogens This reaction will push you out In this, one nucleophile binds the other nucleophile is substituted so what is the reaction called nucleophilic Substitution Ratio Now understand that this is a nucleophilic Why do substitution reactions occur? If needed, look at your carbon halogen Bond was polar, he had polarity in him As soon as I sat at a distance I saw the nucleophile There was a boy and a girl, they were very close to each other We lived with love and affection but one day this If a boy and a girl fight then the girl The poor girl has started crying and the boy is very We were egoistic, we would have had such examples okay the poor girl's heart is broken As soon as a boy standing far away came to know that the girl's heart is broken very quickly okay brother i went to talk to the girl I am not able to do this, I am mine I will only talk to the girl, who knows If my life improves then this is what happened because There was polarity inside them because inside them There was a charge difference so the nucleophile He had the courage to come and attack carbon If there is polarity in any bond If not, brother, please bring the Nucleo file Bring electrophile, no reaction occurs There must be polarity, see this It is written in this type of reaction a nuclei file reacts with halo alkane the the substrate on which the reaction takes place what do you say what do you say substrate substrate having a partial positive charge on carbon bond of halogen you think You must be wondering why this teaching of yours was taught to you by your forest. This forest of boards is a marker question Marker questions are those that you are asked that it is actually nucleophilic Why does substitution reaction occur next? Let's see what happens next, let's move on to what I am saying I listened very carefully, accept that I had an alkyne halide with a delta on it There is a plus on this, delta is minus, you have the most First we have to take nucleophile for example na8 and JE guys love this table a lot do these questions were asked in JE this year also If yes then definitely in your paper in NEET The question will come, O my will come will attack from here x will take out my What happened to me? Alcohol came to me. What happened to alcohol? This reaction yesterday Get oxygen loan from water There is a lone pair on oxygen, it will attack he will push again what will happen Alcohol: It's also clear if you have a reaction This has to be done with aa - n+ later Will he speak Williamson ether synthesis come minus went attacked x minus went what You can see that it has become ether Williamson Ether Synthesis Look at this Ether Become Gonna see if I reacted with a Aa minus attack in karai a will do this Will it come out? Do you see it happening? this is the same one that just got called finkle stein I did it in the name of reaction, see ahead now If I had done the same RX reaction ammonia made me listen carefully, this attack came hit this one, what happened to r n look at it n There were three bonds and there was already a fourth bond Now this x- will take this h+ and go away what happened rnh2 primary amin what happened Primary Amin is gone look here Primary Amin Now you said I took rnh2 mam He said there is no tension, come attack and take it out what will become r a aa became secondary amine you react with r2n He came here and attacked, what happened to RN? RR i.e. Tersh Amin appeared secondary We will start with Amin and become a secondary Amin Start from here, became a Turkish Amin Ahead look these two we like them very much one of ours reaction takes place means nucleophiles are present yes we call them MB What is a dented nucleophile called MB Dented Nuclei File MB Dented nuclear files like those are not our shirts have you ever seen this happen kids stop spamming shivam singh kid one The dignity of a teacher also needs to be maintained do it, it is of decorum class maintain a little bit ok mb dented what is a nucleo file it is like There are no shirts here Available in Atta Market, Sector 18 50's shirt is a reversible shirt wear it from here Then wear blue colour instead of red colour and you are there one day wear one and the other wear the second one the other day which means one day the red one Wear it on top, one day you vomit and then you turn blue wear the one with the titch button The ones with tick buttons are called MB dented mb dented means wear only one are you wearing a shirt sometimes, wear it in a way sometimes in a different way like there is a league Cyanide cn-cs and you are reacting with r one yes or you took it Listen carefully if you react, if you If we take a then k+c is a mine ionic bond So it is negative on carbon here Nitrogen means c minus, carbon also attacks Nitrogen can also attack but Now I attack The bond that I will get is very strong A loving and stable bond is formed but if If I talk about A.S.A. then listen to A.S.A.K. This bond that exists inside, this Kovalenko So poor carbon is no longer left to attack Any attack that would be done would require nitrogen What will happen from the side will become r a triple bond c whenever nitrogen will form four bonds If it is necessary to apply plus on nitrogen then see If it reacts with casein, cyanide is formed Another name for cyanide is nitrile A look with kno2 k positive no2 my one Now children react with agno2 If we memorize it, it means we literally memorize it, and when this The question comes on the boards where you can write If it falls then it is all tied up and fixed Why does it go because I had memorized it, don't memorize it First do one thing no.2 make a face of my mother no2 I mean 1 2 3 4 5 and I have is negative and there is oxygen then its minus Give it oxygen, this is what it is what is the structure of no2 this is no2 of no2 structure of mine if you took kno2 if what did you take kno2 so this is o my free You see o my is free now it is on o - r If he attacks me then what will I do? you reacted with kno2 so my A pass will be made which is called Alkynes Reaction done, now we know the shape of agno2 how is this o double b this is the face this is from o It is connected now who will react now What if poor nitrogen will react r no2 will be formed this is called nitro what will be the alkane formed r no2 which will be converted into nitro alkane speaks from here in your paper 100% question is justified brother hello Do you want to solve the problem of alkane first? The teacher wants to lift this table so that will create a question from the table ok now this is below Are there small things written below? It happens to you now even with your school teacher, right? You must have read NCERT in coaching as well Well, rarely does a teacher teach It is NCERT, people think he is crazy I am passing my time by reading NCERT right now Many people are also saying that NCERT is crazy You are teaching NCERT, who teaches you? Keep checking your level by reading NCERT how much improvement happens what happens when We have studied so much that we tell the child Ok, this will come to you, we think it is okay These three things will come, not with a child because it just happens till here After reading it is yours you must have seen it yourself whenever you read NCERT You study, you do it till here, you should leave it okay friend, it's ok but now I will tell you The things that are written below are very It's lovely there's no space left here it's here Let me just write it down, let me remove this a little bit Let me delete this a bit and write it here hmm I am telling you to look carefully if you r I have got one person's reaction done, first of all r d The COO is seen with Aad COO So what happens is delta minus here If delta is minus then it will attack this It will turn out you will have r' S Aster appeared to be made Aster further look it is saying if you have a reaction of r I did it with lialh4 now l4 is nothing h my he will give me attack, what will happen Alkane now the day this reaction appears in the paper The child comes and says to us, our teacher did not teach that A A4 Alkene It also reacts with halides. See NCERT did not teach you, right? Leave aside coaching teachers, NCERT itself It was taught that the AA4 of alkyne halide reaction with and look at the reaction of r a if You can get any metal registered with RA take it so r minus it will attack this it will be called r now the kids will tell us This was not taught, NCERT is teaching it It's all these little things It is given in NCERT itself ok this is from cbse what, this is not CBSE, this is CBSE State board JE main or JE advanced NEET For any child preparing for competitive exam This is for the child who has to study NCERT I am teaching NCERT I am just Teaching you NCERT line by line I am not missing anything on NCERT Now I am getting everything done for all the kids I have Anyone preparing for any competitive exam if you are doing anything you If your NCERT base is good then you You will create a ruckus, come on, I have told you this What I just explained is the same example now Let me tell you that there are two mechanisms listen carefully to what our nucleophilic Substitution reaction is called SA The reaction is called nucleophilic It is a substitution but it is a reaction It is of two types, one is ours sn2 reaction is an sn1 reaction now What have you done with NCERT? One or four I have explained it in five pages I will explain it to you in a better way but I promise you that no one We will not miss any NCERT thing look suppose i have it okay it's okay Whatever they have taken, accept it from me What is such a compound that we have given Suppose I have a compound like this here it is given, here ch3 is given. Here c2 a5 is given, here cd3 is given listen carefully this thing here is a Three dimension structure is given, hello Now you can see what happens to the alkane that ma'am who is our good one I write it down in small pieces and do one thing I would also like to write this in small size instead of big size let me write the molecule here oh Let me write it down, h. Here, I have written D. okay so you see I have a Carbon atoms are from four different groups is connected did you notice that your each carbon has four different groups If it is connected then such a carbon is visible come on which there are four different groups What does chiral carbon say Chiral carbon Chiral carbon means a carbon which is attached to four different groups comes in one marker well tell me is he coward is he coward no This Is Not Cowardly Why is this not cowardly Because there are four different groups on it If there are no carbon atoms then if there are four different groups that is cowardly okay i said Ma'am here the phone is on the back side The dash I mean the back side I said Maam let me do one thing now - I did not proceed further I attacked from the side, I attacked from the front I am putting the nucleo file so that I can Sterik Hinderland punched him so that he would escape from behind so what will happen, he should go out from behind now Whenever you make this reaction happen Will have to look very carefully at whether This carbon that we had, This is duty, he will be in a plane Hydrogen will stay carefully in a plane Look, this ch3 will stay in a plane, it will look like this that - he is attacking from here and being pushed out, then a In time you will feel that carbon has five bonds are formed while carbon has five bonds he doesn't make it, he just thinks it's five Bonds are formed while a bond is forming The second bond is now breaking in this reaction If I talk about the rate then this The rate of reaction depends on two things one thing depends on your What is the concentration of alkyne halide The second one depends on whether you how much nucleophile is added because The rate of reaction depends upon the concentration of two therefore the reaction is known edge sn2 reaction to means by What is the meaning of molecular reaction two The reaction is molecular by molecular Meaning the rate depends upon the concentration of alkyne halide and it also depends upon the concentration of nuclear files Reaction is known as molecular reaction This made everyone shine, now look carefully ahead What will happen when your - attacked from the front - what did you do, if you attacked from the front then this oh my may your front side come - Your front side is here and this is ch3 this went to the back side ch3 what happened went to the back side and says in it that our reversal happened, what happened what is inversion, eversion is the best For understanding, whatever NCERT has given Look, these three hydrogen atoms are like this It seems you have arrived in the plane - coming from here Now the HAS is being pushed out - came here and Look, this was a molecule, now it attacks from here When it attacked from here it went out So this inversion came to us, a He has written this small thing, yes this not here he has written here as the Reaction progresses and the bond between the The Incoming Nucleophile and the Carbon Atom starts forming the bond between carbon The Atom and the Living Group Will Weaker Than You This is how the result will look like as the configuration is The Inverted and the Coc Figuration of the Carbon Atom under attack inverts in the same way as Brother Umbrella, sometimes it rains very heavily If yes, then you would have held the umbrella like this When the wind blows the umbrella does not turn upside down The process that goes from first to next is called inversion which side it was, now the side of i6 is visible this is called inversion of confine okay So it is written that in the transition state carbon forms a single bond with five atoms but that doesn't mean This is the assertion that five bonds are made Questions are easily created in one marker in the region if there are five bonds then it would not have been possible That bonds are being made and broken at the same time now this one has done a little bit I think everybody has told Somers' story The kids know it just like these two are mine Hands are the molecular formula of both hands the structure is same if here I held a mirror so this hand is the other hand It is a mirror image, right? Both of them are mirrors images of each other since they are mirror images of each other if I impose one on top of this I'll try not to turn it around Children have doubts, don't turn them around Place a mirror in the middle, these two are mirror images Now lift one and place it on top of the other so that they are connected to each other. A thumb is not being super imposed on me here is one thumb here is that fish in water that if they became queens then both of them would love each other they are not being super imposed so they are none Edge non super impose mirror images of each Alright, so let's see what he says now. One thing happened and now he is saying that What is inside our sn2 reactions What is a back side attack? What is a backside attack? Side attack now I will tell you about the back side Why is there a need to attack? Example here is my compound here is S Here is ch3 here is h here is d look here Here there is chlorine, it means chlorine lon There is a pair of carbon and chlorine and there is also a bond So the electron density is higher here. I need to attack this carb now if my nucleophile will come from the front side So this loan pair is mine repels the lone pair of the nucleophile We will create so many problems amongst ourselves Maybe he can't attack from here. so what will be my nuclear file He says, he says, my friend, I will look behind you I will attack him from behind and he won't even know it So now he comes and attacks from behind listen to me if this nucleophile If you want to attack from behind then use Nucleophile Only he will be able to attack where Delta is Only that person will be able to attack where there are more positive Steric This is the hinterland and I have one more Such an alkyne halide is There are three large methyl groups attached here Nucleophiles are not a poor approach whereas there are only two large methylene If the group is attached then the nucleophile it becomes easier for you to approach i.e. Where steric hindrance occurs There will be more back side attacks there Therefore primary alkyne halide has sn2 The reaction is faster in secondary alkyne There is less tert alkyne halide hoti hai so the presence of balki Substituents on and near the carbon atom have a drama Ibingo The Simple Alkyne Halide Methyl Halides react most with sn2 reaction Let me write down a shortcut. Write down ch3 one I write the best best best BS team sn2 is in the best way it is the best sn2 if it will be there then that kind why will ch3 be in one because here The poor nucleophile has no steric properties I am not able to find the target, he can easily go and attack Kills shone Please everyone should get polymer done as well, I request the board yes, I will tell you everything again I'm ready to do something okay You were very happy in your JE life, weren't you? She was teaching me JE, everything was good It was looking great but then the kids I told maam get NCERT done because no We don't know NCERT, it means now this I started from the very basics, you are mine think with your mind i mean in a way when I am studying for JE advance Are things ok or are you studying for mains If they happen then we feel that these are children should come but you won't believe it Ever since the JE exam was over, I have been feeling so I have talked to the children on phone and the child knows what are you saying, I am just saying I had memorized the name reaction and hence my paper It is ready but ma'am what should I do, I am at the base It is not clear, that means there are many children like this who are still getting 30 to 40 marks Whether I talk about Mains or not, how many in NEET Children are such that they only do things by rote learning They have such a desire to learn high-fi things It happens that their base is never clear There is only competition to do more if you do more then that is why specially you It is for children, specially you children For this I thought let's go to NCERT I teach line by line assuming that Even though there are two-three months left for the paper Even if the child doesn't know anything, I will still tell you I am teaching from the very basic to the simplest If you support me from the basics then I will give you everything I will make you stop it, I am telling you straight hmm okay that means this is a very important thing Now what happens as soon as the paper comes It's gonna happen, the kids think friend come on Let's clear the base and read NCERT You sit to read NCERT and you fall asleep It comes, you read NCERT for 10 minutes you fall asleep and then you switch to a new one topic that let's read some more let's read some more And in this cycle, I read your The base is never clear The base is clear it doesn't happen and you keep dreaming That desire to create havoc in competitive exams It is not possible, clear the base, everything It will be good but there should be clarity So work hard with me and I will work hard Otherwise I will not do it, look straight now I have given you what I explained to you that hey on the nucleophile in methyl Small amounts of hydrogen are present here There will be a big attack in ethyl If the group is engaged then the smaller the ch3 the better It looks like it is small, it is not It is big, there are two here, three here If there is a big group then the nuclear file is poor Where will it be able to come, that's why it is unable to come now The story is about sn2 reaction now I will do sn1 I will make you react, listen to me sn1 We give this reaction another name The reaction is called solvo lysis what is solvo lysis solvo reaction means vent and lysis means it happens break down break down spelling Many people have had a breakdown that went wrong The restless heart does break down, doesn't it? It breaks, the break up happened, that's the story So solvo succinate means coming from the solvent You will break down, as soon as the solvent arrives you will break down The reaction is known as solvo lysis What is the reaction, suppose a big He has written a good line and This is such a cute line, this is what it means, right baby I don't stop repeating it by rote and this line is so It's good, everything is clear here Say it and carry out whatever reaction happens Now understand the polar protic solvent Many people do not know the polar protic What does solvent polar mean? What does polar mean? it must have polarity protic means there must be a proton inside it which is worth releasing like water you are there the water is inside the water that means this It is polar, Dapor moment is protic, meaning it h+ can be taken out as if saying alcohol Alcohol is the h+ protic of alcohol as in acetic acid acetic acid is polar is also protic so whenever it is polar Protic solvent would be one such solvent If there is already a Dapor inside then it would be known what do you have suppose i have a turkey Alkynes Do you know what happened now? Have you read about the molecules? This happens many times inside, don't assume that a child is okay a child is a child Is he preparing you for some exam? This is the exam you are preparing for. I am talking about today's people, The child is preparing for competitive exam he is doing well now if all are behind him it may be heard that his teacher is telling him about you it won't happen with you it won't happen with you it won't happen, he doesn't have any parents I'm telling you it won't be possible, it won't be possible for you It will happen to you, I won't be able to do it, his friend heard you won't be able to do it, you won't be able to do it If you are not able to do it then the poor guy knows There is so much burden on the child that he says [ __ ] it friend, I don't want to do it Your heart gets broken, why does it get broken? Because the world has taught you that I won't be able to do it, I won't be able to do it with you It happens but still it doesn't happen to you, why because your heart is breaking inside This is what happens, same story in Solvo Aces What happened in Solvo Asis you used polar protic solvent PPS Polar Protic Solvent You He pushed so much, he pushed so much I pushed so many times, I pushed so many times, so much steric hindring that your bond has become weak As soon as your bond became weak, you Carbon and halogens broke their friendship you got a positive positive Now this was a solvent, like water, it For fun I am saying hi hi you have positive result I will attack you as soon as he attacks you Here it is, I have made this product This is what the world wants, I am this example I wanted to teach only this much through that the world wants you to lose okay The child whose number hasn't come has just fallen The world wants him to fall The world wants you not to get up but you are external things upon yourself don't let it dominate, otherwise you might break I take half a second, meaning it takes half a second and You will be broken, so be careful look this is two bromo methyl propane o I put a minus, now this whole reaction has come I am watching this whole reaction very carefully If I talk about this whole reaction The slowest step is the step which is the slowest It happens slowly, that is our rate The determining step is the rate of the whole reaction It only depends on whether your How quickly will the carbon-halogen bond break? That is, the place where carbohydrate is cut is formed If your rate is the determining step then see Look, this is it, here is the halogen leave This step means leaving the bar minus. that the increase in carb reduction is your rate The determining step is its slow step later on - he comes and attacks that is Fast if I tell you what this reaction is The rate depends only on the fact that how much alkyne halide do you have because The rate depends on only one concentration so the reaction is known as sn1 reaction what is the reaction called sn1 Reaction if you read this chapter for the first time If you are there then you can give lectures, yes Yes, any child can do this session even if it is for the first time Look, you are reading this for the first time, I assume I am here, you don't know anything, okay Today's session is not for those children who Today's session is absolutely pro in your exam It's basically for kids who are either Board exams for the first time in my board exams They know that they are studying for exams It is not known how many dummies are there in board exams There are students who know No friend how was the paper taught in school What kind of questions do all those kids have in me? This is a session for you in very weak organic This session is for you, your base is strong It is my responsibility to look forward to listen carefully child what happens is there any carbohydrolysis in your sn1 reaction What is being made? Carbo Katay is being made now You must know that turkey carbs are cut If you are in 12th then you must have studied in 11th and come from Tersh Carbohydrate cutting is more stable then there is secondary, then there is primary But methyl carboxylic acid is absolutely stable Therefore a tert alkyne halide does not occur Tersh for l a tursh alkyne halide l quab l tert alkyne sn1 reaction is fastest for halides it happens then it happens for the secondary then it happens for primary and then it happens again For methyl so should I say eye shut up and tell me if turk alkine see that mam sn1 reaction Now there will be another question maam tell me one thing Why was there a need to take polar sonet? This is a question of your assertion region, this is your The question of the boards is what was the requirement that you took polar solvent do you know why I took polar solvent so because if your solvent is polar Don't look at the world, why do you lose? Because there are no people in the world who will give you Trying to defeat you, right? If you suppose any teacher tells you this If it doesn't happen then you will lose from inside You go away saying that my teacher told me no it will happen and if the same teacher says this, brother you It will make you feel confident from within it comes, this is what happens if it comes to the house Your parents should support you in this, The paper got spoilt, it doesn't matter, you will do it When there is support from inside from the family members, isn't it? If you got it, you would feel good and you You do it here, this is just the world which is forcing you to break down if you have not taken polar solvent If this had happened, this carbon-halogen bond would have broken not only to stabilize this positive We need water for this, that is why we say The presence of polar protic solvent The bond in will break quickly because carbon Stabilize the water to form the waste can you see now if i sn1 reaction should I talk about sn1 reaction sn1 what will be Tertsh Secondary Primary Methyl Halide Ye then sn1 will never show if sn2 If I talk about then the first one will be ch3 once again There will be primary, secondary and tertiary sn2 reaction show will never do much a very good thing a very good thing Written at the bottom of NCERT he is saying suppose you have this ch2 double bond s is here ch2cl saying its Inside Aquasource If it is stabilized, the bigger the better carbo cut will be as fast as sn1 then here sn1 Suppose he said that this benzene there is ch2cl now here it is saying aquas put it in and tell me what reaction will happen you should shine as soon as you see aquos sn1 There should be a remove carbo cutting visible here If resonance is stabilization then tell me quietly And the reaction will shine, this is the question now that appear in the paper and you think you know no where is the paper made from The paper does not come from anywhere else, okay ma'am Please guide mam the more you advance the crash Will it be sufficient enough to do the course or There is a need to do the material separately as much as we I will make you do that much, you don't do that much You will get it fine whatever we have for JE advance I myself am making DPP for you Whenever I solve the DPP completely I will explain or I want to record it so when I just recorded one It took me about a year and a half to record the DPB myself. it is taking two hours because it is very good The question is advance questions are very good. okay so that's why when you also do it It will take a lot of your time and the more we read Isn't that enough? She is sufficient with him. If you can't do much then you will be unable to do something different No need to do material from can we get a break of hi ram Break bhaiya we are those people who work for 10 hours at a stretch We teach together for the full 10 hours, right? If you take a half-hour break during the session Which of these two and a half hour sessions? My break is starting now, isn't it? You know I have class right now okay and just leave today aside, it may not ring from tomorrow I have class every day so I am finished If I can't do it, I won't get a break brother its ok Mummy is calling you for lunch, take lunch Mummy will eat it after some time, I will eat it now I did not even have it friend, what kind of lunch is this you are talking come on this is done now you Ask me a question and you will answer the question You will ask the first question, do it thoughtfully If you hurry then you will hear from me lunch do it together which thing are you writing Ask this question quickly and tell me who is saying this In the following pair of halogen compounds which wood undergo sn2 reaction faster is I had just solved the JE Mains question paper last year. The paper discussed that these pairs were Which pair will give sn2 quickly? Where did this question appear in the paper? NCERT was asked, you are the one who is afraid tell me quickly which of the two is faster sn2 who will give sn2 comes to mind as soon as you think There should be an attack from the back side Meaning where the carbon on which the halogen is attached is on the carbon to which the halogen is attached Sterik Hinderland This show will finish the matter as soon as possible tell me this little thing it's very nice Now see this lovely question in NCERT The kids say [ __ ] Question I am asking the sweetest question he is saying you tell me predict the Order of reactivity of following compounds In AVE and SN2 reaction the following compounds tell me and the best type would be this Tell me more types of compound Place your order for Hogi Aave, I have placed it first Is on c65 ch2 br6 h5 s c6 h5 br6 h5 to c6 h5 is here br6 h5 s ch3br c6 h5 s is here ch3 It is here br6 h5 then ch3 on c c6 h5 c6 h5 on c ch3 c 65 is here b tell me quickly a and ka Compare the order please give me the order of sn1 Compare it quickly compare order of sn1 quickly don't waste time do it quickly I will teach you quickly the order of A and A, ma'am I had taught that Ae ev means Ae ev means where the most This makes for a quick, stable carb reduction If you remove g then this is a carbo cut, you will remove it So brother, these two are getting stabilized remove g so this one is empty then c6 h5 this is resonance this is simple ch3 remove it Bhai sahib two is resonance plus one ch3 it is best am best turk carbo cutay bana take c6 h5 ok sn1 order is c6 h5 c ch3 c6 h5 b very good so the best good number one this will come number two this will come number three will come, number four will come try it again c6 h5 c c6 h5 b is very big shone great c6 h5 c ch3br c6 h5 ch2br This is the order of sn1 now this question Come on, you order SN2 and show me this maam please show me the order of sn2 in the question had taught that sn2 would occur where steric Hindwing It shined, such questions will come in your paper Are you sitting somewhere thinking that the paper is very difficult It comes clear hey all good let's save it once I save the file very many times Great, we're 1:7 now. Let's continue further I think 60 There are total 80 slides and some blank pages also we have 68 slides If there are questions in it then there are few questions also practice of I will make it Where have we come, well this is what I thought I have come this far, I am not here yet, I have come here on 35th continue from slide it's done Look here, now we will wait till 2 o'clock See how much you can read by 3:00 pm I have time, I have a class at 3:00 Let's try to do maximum till 3:00 pm I will give you yes, if it becomes three then I will do it I will give it to you but let's do it properly now I You can tell a little story in your own way Let me tell you, whatever he has given me is very good i am not denying that it is good It's dirty but now I read it my way so that your base becomes clear Listen to me, you must have studied it in physics The polarization of light is in every particular This light is in a direction called an What is polarized light? Unpolarized light When you put this light through a special prism let's pass it by this is called nicole Prism Nicole Prism What does the rest say Filters out all polarization and polarization of light in the same plane we will consider this is what ppl say PPL means plane polarized light. There is polarization in the plane, now what do you think did you see this plane polarized light in a Any person who passed such a solution passed through a solution of an organic compound You noticed that either the light rotates to the right or the light should rotate to the left Has been If your light is rotated to the right it it's called dextroamphetamine I am teaching because from here one marker two marker questions are made tell me what is known as optically active substance So optically active substance is that which disturbs the plane of polarization of light Suppose you have passed light into the substance and the plane of polarization of light remained unchanged, if there was no change then this The substance will be called optically inactive substance that this substance is optically in Active these are planes of polarization of light do not flirt with What is optical activity? Polarimeter What is Desto Rotatory Clockwise I explained everything to you anticlockwise Di, now I'll talk about a confine listening carefully to the cemetery as I I told you, suppose you have a carbon which is associated with four different groups viz. nh2 is connected to ch3 is connected to is attached to the D if ever the carbon four that carbon is attached to different groups what is chiral carbon called chiral carbon this is carbon chiral carbon one is my chiral compound one what What is Chiral Compound? means that a compound that has Your plane of symmetry should not be Good things have been given in NCERT You have given a very good doubt but it is so Even after reading the explanation the child There is confusion in Kairal A Kairal That's why I'm teaching you my way. hoon ek hota hai kayral compound kayral Compound means that within which there is a plane of There shouldn't be symmetry and ma'am now this What is the plane of symmetry in front of us? Look, let's say I have this compound. do you see ma'am this compound inside the middle of If you pass the plane then this plane divide the molecule into two equal parts will do so if any molecule has a There is a plane which divides the molecule into two equal parts Will divide such plane into parts It is said that plane of symmetry is If the compound has a plane of symmetry then it What compound will be optically active? Optically inact if a compound has if there is a plane of symmetry then you are your what will happen to the molecule optically in Will the molecule become active optically inacto because the upper part is this The more right the light rotates, the lower it will be Rotate the light to the left that much will do it then compound optically inacto this is a glass it is saying look at this This is glass, cut the glass in the middle here I saw a plane of symmetry circle Cut me in the middle on the plane of symmetry I can see my hand now, it's my hand You don't have any such plane in your hand Can I find that plane to which I can give my hand cannot be cut into equal parts for Example, you said ma'am cut this in the middle If you cut it in the middle, one side will be two If there are fingers and a thumb on one side, then it means someone like this There is no plane of symmetry, you say it like this If you cut it like this, a ring is coming ahead While there is a ring at the back, no, here is the ring I will take it off now you tell me ma'am cut it now When I cut, the nails are coming out in front and something behind If not, there is no plane off in this hand there is no symmetry and where the plane of What will be that compound which will not have symmetry caral compound means you have done it thousand times You might have read NCERT but not one thing glowing baby kayral carbon is different kayral The compound is different meaning of chiral compound There is no plane of symmetry in the compound It must have shone now look like this This is one of my compounds, they know it no, this simple thing has given you new and new things I am telling you that this is carbon, carbon There are two same groups, what does this mean? Iron Carbon Iron Carbon Iron Meaning The four carbon groups are no longer separate look carefully now see it is saying some common Examples of chiral molecules are two chloro butane to me tell me if you have chloro butane you let me know do it and tell me is it cowardly cowardly Is it a molecule or not? Is it chiral? Is there a molecule or not? Chiral molecule How to see the chiral molecule So I said ma'am look at this first, look at this Is there chiral carbon or not on this carbon a hydrogen c ch3 ch3 do I need this Chiral carbon has been spotted Chiral carbon is Now I saw if ever Chiral Carbon was a He is a coward carbon, you can do any plane take it, he will not divide it so yes it Is a chiral molecule this question in the paper Let's figure out who is the coward which one isn't it let's do another one there's one near me ch2oh find out and tell me whether he is coward or not no, find out and tell me if he is coward or it is not yes or no sooner maam when is jee main going to start Please mam tell me the crash course for JEE Main Second Feb is going to start from today JEE Main crash course should start from today There is orientation for the batch tomorrow at 3:00 pm Your live classes will start from here I said ma'am this one is carbon hydrogen is o is ch2oh is four different group is yes chiral carbon and because If there is no plane of symmetry then yes There is also a chiral molecule Chiral molecule just to see if there's a plane off Now look carefully if there is symmetry or not there are three things child there are three things yes there is one in these what is mars ek inen shomer inen somers are which are non super Impossible mirror images of each other arrr maam what should i write You are not able to understand, look at my hand What is the hand, Coward? The hand has shone, Coward. I took a plane here okay I took the mirror and gave it to you in my hand Both are molecules, both are chiral, both are same it is the mirror image of the other one put the mirror here so its image will come like this its image will come like this this this this this this mirror images yes pick one up and place it on the other Is this superimposing one on the other? No So what will these two molecules be called? What will Merc be called Inesh Merc Inesh Merc what are the tenths or non super impossible mirror images of each other now listen carefully let's say I have this one compound listen yes understand carefully here it is ahead ch3 the back is h here is d here i have a and the compound is here I put the o behind and put ch3 forward i can win at I am trying to explain in as much detail as possible hmm can you see this is the bean it's same it's same here o is ahead ch3 is behind here ch3 is front o back these two are one What is non super impose force mirror images so what are these two called What would both Somers call Insource Shine? Now if this light is for example 60 degrees If it rotates to the right then its in-frame Rotate the light 60 degrees left one if light if let's say this one hand light will rotate it to the right then it will rotate to the left He will do it on the right and this one on the left The optical rotation of both will end equally There is an opposite, so accept it this is it at 50 pass this is it at 50 overall this will be called optically in active Understanding Mixtures Optically in Active Mixtures You are doing this and this is called racemic mixture R A C E M I C Racemic Mixture Now Tomorrow If someone asks what is racemic mixture then I think you must have written racemic mixture It is a mixture of those natural homers whose There is equal and opposite optical rotation if will rotate a light 60 degrees to the right Rotate the second light 60 degrees to the left If it does then the overall optical station that will come It will come with zero egg and hens call it These are racemic mixtures which are optically in It becomes active now see why it is said that There should be a need for boards because When you are written on the boards Explain what is racemic mixture it is two If the question of number comes to the child's mind then what is a racemic mixture but The diagram just doesn't click with him when If it doesn't click then I can't write If you don't know how to write then you can't make numbers are yes it is ok mam why do you want to get NEET exam done Now brother, if you keep supporting me then you will get NEET The complete theory of NEET will also be taught Why will NEET sample papers also be conducted? It will be done but you will have to cooperate Isn't it true that the channel was first with all the kids Share it so that ma'am can understand if she is working so hard At least this hard work should reach the children I don't want this thing it's of no use that I made this three hour long video on youtube3 I took one shot, explained it to you and it turned out like this It would be better if I kept reading like this Do you teach the product anywhere else? If you do productive work, you will keep reading this Some child's body will remain crushed If there is a benefit then there will be a loss for me as well Brother my hard work will go waste so please share it as much as you can you can change the channel because see this new This is a channel, it is an organic channel, right? I am on this I am not implying that brother let's go this I have no means to reach the children There is no need to play tricks, so much You will share it, it will reach the children If it reaches, other children will also benefit I will go, I will work hard for you I am staying here where 100 kids are studying if it goes further to the children then look at my Your hard work will pay off for NEET, right? I will try to do it 100% but You will have to give, if you support me then I will I started everything when I said I will get it done You will have to cooperate, otherwise see what happens next I'll back off okay let's go let's ask questions, ask this, do this So it is very simple, well I told you I taught it at a good level, it is very simple Do one question and show the question number what is a Identification tell me is this coward or not one me tutu me natu 3 me tu is this coward Is there a coyote or not, how did ma'am want to see it I said, choose one carbon and beyond that, there are four different There should be groups, but these are two similar ones There are two beans so this is a coward it shines What is an iron, you must have understood it, I think come on Great, now listen to me carefully about this thing now i have two or three words to understand a It happens Inversion and there happens to be one Retention Retention and what it means look carefully suppose I have sn2 reaction what happened earlier in karai sn2 something like this okay what was it before it was something like this h this is ch3 assume here you assume cd3 take it here i said in sn2 If there is a back side attack then whoever comes now let us say that my right hand is raised forward The side has come ch3 this is it h this is it and this which it's cd3 it went backwards whose cd3 I went to the back and said, brother The new group that is coming will come from the front side. and whatever came out, whatever came out, it was from the back came out from the side means in your molecule what happened inversion inversion happened that came from behind your confine got vomited now Suppose I want to do this reaction sn1 the way i react in sn1 way I am going through the sn1 method, the meaning is something like this look carefully the first ch was here this is ch3 This is c2 a5 and you can put it here There is hydrogen, you said ma'am, first of all As soon as it comes out, it becomes c25 this is made ch3 this is made h i have made it Carbo what has katay become carbo katay now carbo Katay is planar right this is planar 120 Now what does it mean to say degree? oh2 went back this c2h 5o went this h ho When he comes from the back side then ch3 goes forward that side has come this h is this c25 so what You understand that this will become 50 at 50 This means that both of them will be inseparable from each other. If it is Mars then we will make it the overall will say racemic What will the overall mixture be called? that will be known as racemic mixture ok Can you include NEET PK in this session no no no neet ke pwa q in this session In this session we will not be just one and only If you are doing NCERT then NEET K P Y why is it done je k p y koo No, all of them in different sessions. I will get it done because right now you will come forward We will do it in the coming sessions but not in this session All these things shone on everyone I have written it in English I have demonstrated it in Hindi and am saying What is Eversion Retention Racemization yes, I have explained it all to you This is also the same thing, no matter how much you write it It's all that I've kept for you He got it explained in short It was written in great detail, let me save it once I will do it, then we will continue further let's go save the file let's go 42 Our pages are complete now we are 43 Come to the page, understand things carefully Now I am going to teach you something new its called elimination Which reaction is an elimination reaction? Now the kids don't even know its base listen suppose carbon carbon carbon carbon carbon carbon carbon carbon here halogen here halogen is your functional group What is halogen? So first of all we need to know about halogen circle it I've done it circle it now The carbon to which the halogen is attached is called The carbon from which alpha carbon halogens are derived is connected that is alpha carbon alpha the carbon next to the carbon here and here what are these two called beta the hydrogen above the beta carbon what is that called beta Hydrogen means hydrogen on beta carbon What will be called beta hydrogen shines now my listen, this is what I have told you first location of alpha beta carbon in a how to find out the molecule listen to our There is one base, the name of the base is alcoholic k alcoholic k means alcohol drank koh-e-fiza Tursch Buto Side Potassium Tursch Buto what is all this, this is their base It is the same base but written under different names So this is the work of the Pihar's Vaj base, you know what happens base goes to beta proton It will bring beta protons meaning beta carbon But it will bring the hydrogen here He will be kicked out because one hydrogen is missing from your molecule And another halogen came out, it is called D Hydro halogen reaction is not written here So I write it down as D Hydro Halogenation Reaction De Hydro Halogenation reaction means d means removal a What is the removal of hydrogen and halogens? It is called dihydro halogen reaction done everybody shined well so base what is the job of the base what is the job of the base that it the beta will take the hydrogen because you have beta took the hydrogen of the position so The reaction is called beta elimination reaction ok now be careful look suppose i have this molecule s s s s 1 doti chapa de hai He and this b are saying this here You have alcoholic Now listen carefully to the work of an alcoholic what happens is that it will take beta hydrogen first The thing is you should shine beta hydrogen so what is this b this carbon attached to alpha so this carbon will be called beta a this carbon if we call it beta then either this one h take it and if this one comes out then what will happen c S C Double bond C S One of these is this or that Take this h and the double bond comes here c C C C Double Bond C Now you are asked tell me which of the two is major and which is minor Listen to me carefully now in NCERT I did not provide it as an add-on from my side I am telling you that if ever you are asked who How do you know which alkene is more stable? Will you circle the double bond first? Circle the double bond. Now look at the double bond. How many carbons are attached to the side of How many are these now attached to the double bond Now circle the sides of the double bond What will you call carbon? Alpha carbon the carbon alpha to the double bond how many carbons are there 3 4 pa i see five Here is the alpha hydrogen. Do the double bond here. Circle the carbon next to the double bond how many one how many hydrogens are there on this two alpha hydrogen where alpha hydrogen The more stable alkene will be This is why this major product is now NCERT people have written such a nice thing given that the more Alcatel Alkyne is the major The poor kid doesn't even know about the product What does peacock alka leted mean to you Stop thinking so much, circle the double bond do the carbon next to the double bond we say alpha carbon where alpha The more hydrogen the more stable the alkene where alpha hydrogen is more, that is alkene More stable now here's a nick I have given the paragraph and you are saying no ma'am sn1 Which happens faster or sn2 which happens faster it will be much faster, say e1 will be faster e1 e2 will happen soon now elimination will also be two-three is of type e1 e2 sn1 sn2 if I have the most First, let me talk only about NCERT I am not talking about neat I am not Talking about Mains I am talking about NEET and Mains then I will teach you sn1 sn2 e1 e2 I will give you the full details this is a carbon on the carbon either c2h 5o - Come attack and take out the halogen The second possibility would be this bulky base This one should take this h+ this one should come here this one should come from here he is saying that there will be elimination or There will be a substitution, I will explain it to you in short I give you the substitution will be versus Elimination will depend on these two things will do it if you see heat written on the paper If you find high temperature written then you You would prefer elimination because when you The bond has to be broken right, look Elimination means you broke this bond double bond is formed whenever heat or high temperature You will get it written, keep the elimination in mind and if yours is any nucleophile or base if it is small like c s Pay minus he will do the substitution if your do you have any molecule like this Buto side which is so bulky now look at that This would be a big attack for him here it would be very difficult to do so if But if you take the base then the elimination will be small If you take the base then substitution is possible but Short of Elimination vs Substitution Now look, this is a very big topic. If you study for Mains or NEET also I am here so give me a lot of time It takes hours just to debate this matter whether there will be elimination or substitution It will happen but you can start preparing for boards now. Now you are clearing NCERT as a base. If you want to do it then remember this Elimination occurs where the temperature is high Substitution and elimination happens there where the base is bigger it is called hey tarsh o mine k p now you understand Tur butoxide is gone, I mean look at this ch3 co p minus k p then the bigger the base There are more chances of elimination there yes It's okay to go there after elimination My chances will increase, it's good now don't let him drink water even once because Now it is too late to continue teaching I drink water once while teaching Let's continue, there's just a little bit left ok sir you are saying bring it good yes what was i telling you yes a child Writing in the chat that bouncing back should I do it or should I get a booster brother Both are very good in themselves I praise them both Because I am teaching both of them. bounce back good because we've got you I have studied the complete detailed theory, I have taught everything The booster is good because it has Whatever the theory is about bounce back, If it is there then the booster is a super set of meaning Booster is a super set with lots of stuff in it Because the practice you have in the booster This is sessions which is our new boost now If not, then the booster which is in your There are practice sessions in which we ask questions will practice all those new questions We have taken a bounce back just 2 years ago First it is ok so there are no new questions in it a so if you're taking a booster Definitely he is the best because his Riggers inside means dirty questions We will practice you every day You will get a DPP which you have to solve If you have to, then you don't know how to do it yourself then you are definitely a part of booster We can force you to work hard We will get it done because look hard work is necessary ok there is only water no come on NV sir where is NV sir call NV sir now NCERT of chemistry what can we do in one shot of this let's do this Now I am also happy with you I will introduce you to the best topic We don't want to tell these stories. which one I will give you in next 10 minutes I will tell you the whole story of RMGX Look, never before in the world is the mixture of carbon and halogen This love, this love, you have to break it So you have to put metal inside it. You already know that a person loves a prisoner We are very deep and madly with each other, right? Blinded in love with each other they are now If you want to break your love then tell it to a third person If you have to bring it then it is third person metal it can be any metal but right now I am using magnesium I am talking so what will happen come AG become one will go now look at r mg x r pe aa will go to delta minus magnesium p delta Delta Plus on Plus and Halogen is same sikh halogen p delta minus now ncert We always say that it is nonsense He gave such a cute little line The line is that from here to the advance question it has been made look it is saying in the Grignard Reagent The Carbon Magnesium The bond is carbon magnesium bond Kovalenko but there is a difference in it Polarity due to electronegativity is with carbon pulling electron from electro positive magnesium carbon pulls electrons from magnesium while The bond between magnesium and halogen is Essentially ionic, what a lovely thing it is What a beautiful thing you have given me brother Bond of Carbon and Carbon and Magnesium By the way So don't give any the bond between carbon and magnesium which is It is made of carbon magnesium by the way Bond anyway what is our Kovale but It has ionic character hence polar but the bond between magnesium and halogen which it's perfectly ionic let's take a minute drink water then continue do Now move forward and understand it carefully You know this R minus, right brother? Sir, he is such a big glutton, it seems There are many people like me, I haven't even Two-three days ago I thought that it was my birthday 90 days are left, I am telling you the truth Nana I am here looking in the middle like this I used to be very fond of my birthday Well it doesn't happen to many people, it happens to me if it is there then I was counting it as if my There are only 90 days left for my birthday now what should I do what should I do so I no 90 days challenge thought let's do 90 days I won't eat fast food for sure Do you know fast food is bad for us? I went first of all for my health I said that the small diary doesn't come Isn't it true that a small diary doesn't come in ₹ I brought it and wrote today is my day one I am not eating fast food for 90 days challenge I will eat Well, I had a hard time spending day one Then the next day I wrote Day 2 in my diary. that no fast food zero sugar now she read I don't have the diary, I gave it to Naksh If not, I'll show you, okay then I spent the second day like this, now yesterday We were very late here, weren't we? Was working in the studio quite late When it happened, I was feeling very hungry It was raining so I didn't feel like it I assumed we had gone out to have tea, so I I saw a brother holding a knife standing right now The rain is coming from the coffee is in front of you It's just that I didn't feel like having tea I caught it and ate it okay now when I caught it If you eat it then it will be my 90 days challenge later yes This happened the day before yesterday, yes it rained the day before yesterday I was waiting so I ate pakoras 90 days challenge It was useless, I thought it was no big deal There will be a cheat day, there will be a cheat day Then when cheat day is over then it is tomorrow's turn When tomorrow's turn came I thought that my friend is hungry I am feeling sleepy, let's eat momos, then I will If you ate a plate of momos then it means half a plate My one who is red in our class Come on friend, I am here to give you momos too If you give me homos to eat, then I will eat momos Then I started my 90 days challenge So it's useless now I don't know Why did I tell you this story? Yes, I remembered Bukh Bukh, those who are like us People are very very foodie, we are deep madly in love with food we have a lot of food If you like that 90 day challenge then what is 10 days I can't even take the challenge if I eat When it comes to this then it is like this which is ours The Grignard reagent is RMg. This is r Minus na is very gluttonous, bukh bu half Kha khad bukh is spelled like this Perhaps Bhukkad means number one food He should see h+ somewhere quickly will eat him now suppose you have Grignard I put the reagent in water by mistake, brother Sir as soon as he saw the water he took it to h+ gone alkane became you rmg one I mistakenly offered him alcohol that brother he drank alcohol It is lying there and I am saying it doesn't matter as soon as I see it h+ I will eat the alkane you made a mistake to r edge one in front of the primary amine itself why didn't you keep it, it looks a little h+ to him no it makes an alkane, this thing She is so cute and look even water alcohol Amines are sufficiently acidic to convert them into correspondingly This is why we call Grignard reagents In whose presence do you always keep We always call Grignard reagent as D kept in the presence of dry ether so that If he could stay away from water, this happened The story of the Grignard reagent now Assume what the Grignard reagent does You rxx100 pulls it and brings it otherwise That nucleo file is definitely there somewhere But if he hits his head he will definitely attack Now I will tell the story of some name reactions Let me start and this is the question I have I remember my time when I was in class 12th I had this question in my boards paper I came and appeared in your ma'am's boards I got 100 marks in chemistry, okay 100 I had good marks in chemistry and maths I think it was 94, 96, in physics also it was 95 It was 96 so I don't remember it exactly now. And my percentage was good in 10th, it was 96.4 I was 97 p something is now exactly what I noticed I don't know which one had the percentage but yes I am telling you this is my came to the boards during my exam time And this keeps on coming i.e. paper every year I do come in the five marker, right? Sometimes it comes in two markers and then in front Look, first of all all the kids know this If you take an alkyne halide then If sodium is put inside then alkyne halide is taken These two will go away, what will happen r This reaction is called Woods reaction If you take an alkyne halide, it will Add sodium and take an aryl halide lia aryl halide it is called on benzene r this is called woods fitting reaction I had given it somewhere, it's called woods Where did the fitting reaction go, so where is the correct reaction Look here, this is called woods fitting There is a reaction and this is also your reaction Are halides are two sodium add one and you Aryl halide is taken when these two combine together When we combine these two, we get biphenyl this is called fitting reaction die It is important to remember the name of phenyl dye phenyl this reaction is called fitting so what is woods phytic what is woods phytic What are these three reactions that struck you now? I am not a very sweet thing to you He will teach you substitution reaction It is explained in three to four pages I will teach you my way If you are wondering what happens to the child I am in chlorobenzene This question can also come for two marks in four It is not that any number can come If you fill the pages, you will get many more numbers Children have the illusion that school and The more pages in the board papers The more you fill it, the more marks I will get There must be some intelligent teacher who will teach the kids you are trying to check the brain of a If the question is written in one page and written enough So I will give full four to the board people too I will give you full four marks, if the question comes then it will be five marks. isn't it but if you had turned the same thing around like this four are being written by beating If the pages are not filled then it is negative meaning negative So let it not happen in your boards and will cut you and you will get only two marks out of five If you give me the work then I don't have to write nonsense in the paper that things need to be written on paper, it is okay You have to write things on paper, don't write nonsense that it would be beneficial as more pages would be filled No, doing the paper is an art. Presenting a paper is an art Like look at this O minus he is asking that Nucleophilic Substitution Reaction Why is it not easily dissolved in chlorobenzene? Write it in points, as many points as you want You will write so well, what can I say to you I am also saying this, right? I have given so many long things in NCERT I will make you do it in my style I mean I'm here in points on the side I explain things to you because as much as You will write that much in points in the paper You get good numbers, let's say these are five numbers When the question came, then you The first point you will write is that this carbon And halogen is its bond partial double has bond character because there is resonance because you have a partial double bond character second means partial double bond Character Meaning Bond Becomes Stronger If the bond becomes strong then this bond breaks The second thing that will become difficult is this carbon This is sp2 hybridised carbon while the Lo, if this was the case then it would be sp3 hybridized. Carbon would now be sp2 hybridised carbon Percentage S is more in Percentage S more means the bond is smaller because this The bond is short so breaking this bond This becomes difficult because of NCERT people It is also written here, look, it is saying this Resonance effect is happening Resonance Due to the effect, the electrons here The density is high, the bond does not break It is said that there is a difference in hybridised It is sp3 hybridised whereas it is sp2 If it is hybridised then this bond is strong It's hard to break it, it's hard to break it It is much easier, the third one is saying accept it You said come on maam now accept that you are thirty You are saying night, you said ma'am look at this try to get the nucleophile in here you will do it brother as soon as you get the nucleophile Will you bring this also, this is electron rich too If it is electron rich then the nucleophile He will not be able to approach Ram ji's saying I am leaving, I will not come back Are you getting repulsion, someone told you ma'am okay sn2 won't happen someone said do sn1 look i said get sn1 done g cut carbs This will be formed on carbon with double bond Do you know how much of a sin it is to bring out the positive? It can neither be sn1 nor sn2 nor ssi The bond can break because the bond is strong has partial double bond character and The bond length is small and hence very If there is a strong bond then the reason is all these reasons so helo arene which is nucleophilic all If you don't show Tashan reaction then it is not Possible for hello uns to show Nucleophilic substitution reaction in which The child knows the truth about this, it is just the mains. I just finished my paper two days ago. I think you will also agree to this JEE Main paper is a question of Assertion Region I am talking about the boards separately because they are very This JEE Main assertion is simple, right? The question of the region is that aril helide de do does not undergo nucleophilic substitution Reaction Statement One to Statement Two The question came just now in the paper yesterday are over Look ahead and see what happens if you agree chloro benzene is chloro benzene you You are forcefully telling me that brother na8 623 Kelvin and very high pressure 300 atmospheres is one aa pressure right now You have 300 times more pressure If you apply it then this reaction will happen Do we have to memorize these temperature pressures Yes for board exams, yes for NEET yes you need to know the for je mains Temperature Pressure ma'am friend this is a very dirty thing so Now how will we get it done, so see how will we get it done what do we do with this chlorine Here's what we do Ortho Ortho put no2 group on position do we put no2 group or paragraph on position We put no.2 group on the position, now you think what does this mean or are you here On ortho position only on ortho and para position you can no2 why do you do this look at this Understand this thing, write it in the paper This no2 group is worth this electron will withdraw this will go here this will go here it will go similarly you see this will go here it will go here it will go here it will go here Do you understand this because of going? that this one has a delta positive on carbon will increase as delta positive increases Nucleophiles can easily come and attack If it can then what happens because of no.2 group The no.2 group that you apply is this minus teaches resonance effect minus m effect Similarly, it also teaches the Aa effect Because of which the bonds of carbon and halogen Delta positive will increase on carbon If the delta positive on carbon increases then Nucleophiles react easily with the help of Now what you think is an empty sample Reading the paper will not get the job done You should know how to write this, only then will you know You will write it, that is why if you believe that one so now what do you get if you put nitro group Earlier you had to pay 623, now you have to pay 443 You will have to give Kelvin, not this temperature rote ortho and para two nitro groups and low temperature will have to be given and if If three nitro groups are added, then children Even if you do the worming just by adding water the product of the reaction will react this is called picric acid and This is the name of this 246 Tri nitro phenol is called picric acid 246 tri nitro phenol ye This is the whole thing that I showed you Exactly the same thing, now a question come on look can you think now this is yours The question of the paper is that no2 group is only ortho And why is it successful in para position? What is it about meta position that makes it useless? Will be done Listen, what will happen in meta position, look at this chlorine and here you have the meta position I put number 2 on it, what did I put on meta no2 if no2 is placed on meta this electron It will pull the electron very well He will pull it but see this as soon as it attacks - It happened, you said - it will come here, it will come here now Look at this, whenever it is coming this way accept it You said that mine is coming here so one bar negative came here then this came here This went here to say what it means to say negative means that anytime the nitro group is If it is in position then it is -a or -m group It does not show the effect at all will not be able to take the electron into itself if it gets electrons only in benzene roaming around near nitro group electrons are not coming so if nitro it is in group meta position, it is of no use If it is not there then it will be on Ortho then there is resonance If it happens on the para then it will resonate He is of no use on meta, he is no one resonance doesn't do yes ma'am 29 shift one A question came in me, it came in my mind, this question also came in my mind was that if you keep increasing the nitro group then Why does the story keep getting easier then all this what is the use of neet also then all these things If the base is clear then it is a very good thing has this thing become clear to everyone It is done, anyway, I will tell you in great detail someday I will tell you how to actually do that one one one one what do you say this is completed If you ever tell me the whole mechanism, I will definitely I will teach you for your boards for a good Clarity of NCERT you should know nitro if ortho pay then minus a show will do nitro para pe even then minus a It will show but if Nitro is in meta position If it is there then it shows inductive but meezo Does not show Meric or Resonance effect If you understood then this was the whole story about Nucleophilic Aromatic Substitution Reaction Now we come to a new story Its name is electrophilic aromatic Substitutions Reaction Now I will tell you this once Again a previous year for you guys The question is so cute and simple This is the line from NCERT but there are many questions like these Children do not know anything, now understand children We have a new topic which I I teach Bindi in the name of Bindi Effect I teach you in the name of effect, learn it once yes it has just appeared in JE paper this year Bindi, do you have any chance of getting into NEET? what is the effect when I was small There used to be a serial, she used to do it like this, it used to be written There was no such serial, that Prerna and Anurag The one in which Anurag dies five to six times Change happens and who is one Mr. Mr. Bajaj yes Mr. Bajaj wala There was one serial and Komolika used to do it like this did you see that serial and the serial was I wrote something like this, she does this to me she doesn't know how to act that much but she used to do it Like this, do you know who was Komolika? Look what kind of bindi she used to wear, so long and so beautiful There used to be a plus or a one in the middle I haven't seen the Nagin serial yet Till now I have heard a lot about Nagin serial but It means the snake has become a serpent, it means the snake has become a serpent Strange even in serial Nagin serial She wears a bindi and there used to be another serial Gopi Bahu and before that that serial came because the mother-in-law was also once a daughter-in-law, did you see? She must have applied round bindis like this Down below negative like this down below Parvati wala When the serial used to come, we had two types of There are bindis, one is this serpent bindi and a plump dot okay now if you suppose There is an atom above benzene on which it Chubby simple lone pair or negative charge what is this negative charge so that What will an atom or group of atoms always do will give electron to benzene then whenever it will donate electrons to benzene look like it has I gave it to him, it came here, did you notice one thing will it come to benzene or else para The negative charge will increase at the position is ortho and para of benzene the negative charge will increase which is why it is ok I wrote it upside down because of which what if we say that these groups this is the electron density on benzene which is They add electrons to benzene Density increased at one ortho position per para position and another ortho position whose Because of this, whichever electrophile comes, it will either would you like to come on ortho or para Such groups are called electrons donating groups and these are called ortho New group of Para Directing Groups Trying to bring it to ortho and para position we do but if you have, suppose you have a There is such a group for example where there is a serpent dot is like C double bond sing or assume that you have one like this The group is like no2 no2 has n on plus here s has this It is Delta Plus and it is visible, so it is so clever I am like Komolika now, right? I will show you how to do it like Komolika Komolika is so clever that she gets rid of benzene electrons are pulled out when it comes from benzene it is visible that the electron will be pulled when this will pull electron from benzene these are called These are electrons with drawing group electrons are being pulled from benzene which has Because if you look carefully, you can assume that I'll show you this one by doing it here double bond n pe plus o - o my then positive I'm here now continue this Resonance You must have studied a little bit of class 11th don't say that it doesn't come at all yes here it is positive please continue Then you will see that the positive has come here i.e. saying that means saying no means this what do these groups do our ortho and para position at ortho and para position Now whatever is mine brings positive results He is an electrophile and will say, Bhaiya, I am ortho We won't come on para, we will definitely come on meta If you would like to come then what to do for such groups What are Meta Directing Groups? will speak meta directing Groups this story you i am sure her The child might have learnt it in class 11th but I read this story even in 12th class I am telling you this, look, because of this if I I should talk about halogens, write it down here if I Particularly if I talk about halogens then If halogen is attached to benzene, then suppose it is a single then it donates its electron to benzene give the right ortho para directing groups i believe this is ortho para Directing groups are new groups Ortho para comes but do you know halogen are so electronegative that they from benzene due to inductive effect Electrons pull, even if they do pull then this Well, the plus A effect shows and Minus I effect pulls sigma bonds because of which they get minus If it is dominating then it is ortho para directing but these are Deactivating group involves many children There is a lot of confusion and they say know No, where did this NCERT line come from? he is saying that there is a halogen atom because of its minus a effect has some tendency to with draw the electron from the benzene edge a result the rings get some wt deactivated As compared to the benzene and electrophilic The rate of aromatic substitution decreases This is the question that comes up in the paper that chloro Difficulty if benzene is chlorinated occurs while chlorination of benzene it is easy because the one who is yours Although it will show plus A effect but Because of the minus aa effect those electrons attracts the halogens so halogens are ortho para directing but deactivate group this is very Small and cute things who should be considered ok Hi ma'am by mistake I enrolled in advance batch i want to enroll in come batch please help me what should i do who is the kid mani kant mani kant kids you write a mail class@gmail com your registered mobile The mobile number from which you have entered the app Write down what you had registered for, write it completely once give and take try to figure out anyway ok we will try something, it will happen I will get it shifted but first write me an email with your registered phone number ok chalta hai done Once I No, I will save a small file some day Nishant sir was teaching, he saved the file No, hey brother, God is completely with us Sir, the file has disappeared and since then I am scared hmm let me save all the files Now let's continue further brother you know this now we can talk about electrophilic I will continue to teach you aromatic substitution What should be done in case of chlorobenzene Chlorine has to be added in the presence of fecl3 So what do you say about chlorination? It is either will come here or will come here then see 14 13 t 1 2 Steric Hindering in Vat It was great if you used chloro Nitre was concentrated inside benzene hno3 h2so 4 so what will become nitro The nitro group will either come here or here listen carefully here steric Hindwing Even JE kids get confused now i ask you tell me what is its name tell me what is its name tell me its name is it one chloro should it be four nitro benzene or one It should be nitro four chloro benzene think this is very lovely question and NCERT is there a question in your paper, you cry You pretend that we don't know, you know This is the seal, then it has me, Then I consider Nitro a good group So we absolutely consider it useless Whenever you start numbering, you will start from here If you do 1 2 3 4 then you will get 1 chloro fur Nitro look no chloro fur nitro benzene is this small thing, it doesn't shine paper come on this is chloro benzene concentrated h2so 4 h2 s2o 7 is also written in the paper You can also find oleum written in the paper If possible then either so3h group should come here or so3h group come here now this shine Sulfonic acid should be the acid of acids this one will get number one 1 2 3 4 will come now Four Chloro Benzene Sulfonic Acid This Major The product is no exception as You thought it was happening now see if ch3cl and hydrous in chloro benzene nothing in the presence of alcl3 this is alcl3 mine will go out or ch3 will come here or here it is shining it will come here or here now look at these do numbering iu pek namin you had to do chloro chloro then one more If it is a functional group then numbering starts from here If you do then one chloro to methyl benzene whereas This is the major, there is no doubt, do it here there is presence of ch3cocl and hydro ccl3 shoot this co3 group will stick co3 Group now show me one thing to do Write its name, show me its name Show me now this is what comes next tell me that acetophenol The child is becoming that it does not shine Listen what is being made now this is your main no functional group ketone is a better I think you will know the functional group Doesn't everybody know ch3co call ch3 Acetone ch3co and here is benzene it is called There are acetophenol and acetophenol here You have put it here, right? If you add 's' then see, it will become aceto phenol and do the numbering do the numbering this Look, this has become acetophenol, this one, this two. two chloro aceto phenol one 2 3 4 this aa Jayega Four Chloro Aceto Phenol Oho Eraser Four Chloro Aceto Phenol, look at this if ever If you have read NCERT in such detail then It'll be fun if ever No, even if you have read NCERT properly So this is all the fear that I feel inside it will be clear that chlorine is electron with drawing group yet it is ortho para directing explain why now this is yours There was a question of 5 marks in the paper I also have this question that I should not accept the parts won't you write one part? it will come or this is what I have taught you so the fact that What you learnt will be useful for you in competitive exams It comes and if you write down the logic that you have learnt Those boards have been made, is there any difference There is no difference or this or that of the boards Some different things are asked in JE and Some different things are asked in NEET, this creates confusion The only thing that is different is NCERT which you will do it the way So let's save a little bit more. How much time do we take to move the file forward again The time has passed, it's already two o'clock, I have The limit is 3035 minutes I will read you more I will give you how much it is about to happen Why was I so tensed, let me mark it I am telling you which alkyne halide you will use from the following what would you expect to react rapidly by sn2 mechanism you can use it You will answer the third question, take whatever I say You will have to answer them one by one Answer the third question in which of the following pair which compound will show faster sn1 Identification Gali Maro Complete this 6.9 Complete the question, it is very important There is a mark sir don't stand behind the mirror like this Ask how much time is left for our second There is a class at 3:00 pm sir please look at this page one went, this one remained, this one remained, this one remained After that we will take some tests ok so almost We 25 listen sir give me its charger it is on 2 go please or bring this for me yes charger Please give it to me sir, yes please give me the answer brothers which alkyne halide from the good that where did my question go this is in which of the The following pair of halogen compounds which Compound Undergo Fastest sn1 Reaction sn1 there will be a fast variety sn1 fast where Good carbo cut is being made here turkey bun here secondary is being made so Obviously A should have shined Everyone has shone, come on, now show us the next one By completing this A B C D E R R D Show me I'm doing it with you If you first show magnesium then you will make edge b Magnesium shows the presence of dry ether I'm in a bun this went Okay yes where the bulk group will be very good Nishan sir is calling you kid yes : we will meet at some time sir tell me brother now divide It's gone okay now it's divided wait let me open it here Keep telling me about the session and write the answer quickly go yes I have opened the session yes your I will see the answers, come on I saw water brother water what does grignard do what is reagent bukh bukh means eating h+ If you go, do you have a cyclo? Hagen was made everyone has a lot of Cyclo Hagen hi good now he is saying in r b add magnesium i said this is r age b Becomes better in the presence of dry ether yeey this is done c now add d2o carefully look he is saying if you want to insert mgbr2 then it will take r - d and d is coming here c c c d came here so here it means rxx100 r b flashed or not flashed quickly Tell me did everyone like this story? Cyclo Hagen will shine, be happy now So now become This bad friend will go, a very bad question what are you talking about, I am saying ad in one edge put it in it will come to me as an ad It's done, it's saying, if you pour water then it will become a barrier I will add water and it will be ready, then he is saying If you add sodium ether in it then it will become odd and odd if you go then did you have an RD wasn't it It did not shine Everyone is getting these questions and you are scared It shone R D It was this this this Isopropanol Read this entire page and underline it You yourself explained a lot to me You must have studied from teachers, you must have studied in schools also I must be my teacher too, I remember when We used to come to this page about poly halogen Compound is the maximum that we are taught I thought friend you should read this once is something which is absolutely theoretical please read this and its good and Let me tell you, questions about this are asked in schools too. are not given with the thought that friend this What small things do you come asking but nowadays Be it JEE Main paper or NEET paper Whether it is your bit set paper or Nowadays your board exams are based on these things which are actually practical things in life Do you use it, the question was asked This question was asked in JEE Mains few years ago How much chiral carbon was inside DDT Well, this question was asked a few years ago that ACOc means some gases were released You had to tell me which of these If sea is poison as gases then complete chapter one on the side but these last three pages are On one side, let's see some poly halogens He has given it first in the compound dichloromethane dichloromethane ch2 cl2 do you remember we just said its name I read methylene chloride methyl chloride NCERT came to the third place after reading the name If I have given it to you then you must read it, I am telling you dichloro methane is widely used as a Solvent as a Paint Remover Remove Paint Edge is used to remove paint Lent in Aerosols and as a Process Solvent in the manufacture of drugs All of this is used to make drugs etc. there is no need to memorize things there is nothing to memorize You must read it, it is saying it is also Used Edge Metal Cleaning and Finishing Solvent is used to clean metal Does Methyl Chloride Harm the Humans Central Nervous System (CNS) it is a very sad story if I take it Levels of Methyl Chloride in the Air If I inhale, I can hear a little more The problem starts to appear I started feeling a little dizzy at higher levels. As we go, we start having nausea and such isn't it, the hands and legs become numb and if You made direct contact with the skin Then there is a burning sensation and If it accidentally gets into the eyes, it can cause eye damage the cornea itself burns this was of ch2 cl2 is one about chloroform chcl3 Methods of anesthesia in childhood chloroform is mainly used for Employed as a Solvent for Fats Alkaloids, iodine and other substances ok is the major use is in the production of freon refrigerant r22 is now in the paper go tell me freon refrigerant r22 Which solvent is used to make it So that's chloroform, we don't know that it happens because we have not read it, we think This is out of syllabus for JE students For NEET students For BITSAT students For those with boards, for everyone It is important in old times It was used as an anesthetic then That is a little bit central to our CNS. It made the nervous system work a little slow Then he says use it more than this Meaning, if you smell too much then you will get headache. Then such dizziness becomes chronic Long term exposure to chloroform If someone in the chloroform industry If it works then it can damage your liver also. Let's listen, this is important, here it is your one marker so what will you do which one is this It is given in the sample papers, it comes this is one marker saying chloroform is metabolized to force genes and there is no end to the kidneys and some people develop when the skin is immersed in chloroform to you Let me tell you this is chloroform of chloroform If you put oxygen inside or sunlight No chloroform bottle in the presence We are dark, meaning we call chloroform dark store it in a color bottle so that Prevented it from oxygen and sunlight can go if oxygen is combined with it This is a very bad and dirty gas which is named phos gene cocl2 dis gas is known as phos gene gas one of the poison These are the gases that we need to stay away from Question is from previous year question of your paper Whether you believe it or not, I am a dear one, Tenu. look tell me the truth there is only one id form id form I mean do you know what the smell of chi3 ide form is like whatever happens is the same as these doctors that smell there is due to iodo The form comes and I will tell you sometime Is this at the pencil shop, the stationery shop? When you go to the store to buy a new pencil, When you open the box it smells like that he is saying this in the olden days Butt was used as an antiseptic Antiseptic properties due to the ide form does not have antiseptic properties R basically because of free iodine it is ok And not due to id form then its filthy It has a sea smell so I don't use it these days then it is carbon tetrachloride ccl4 carbon tetrachloride what is it used for the manufacture of refrigerants no prop lens for aerosol scan it is also use at fee stock in the synthesis of Chlorofluorocarbons and Other Chemicals D This is used at home like grease If there are any stains, remove them but it has been found that it Liver cancer occurs inside humans The most common effect is that it becomes disease I start having headache and vomiting. If it starts, it can cause permanent damage goes to our central nervous system You become unconscious and even death occurs is exposure to ccl4 can make the heart beat Irregularly and stop brother more ccl4 If you look at the beats of the heart, heart beats it gets damaged and atomic fire I deplete our ozone now From here comes a literal question that what is freenus You must have also read what are these questions not the ones which are chlorofluorocarbons than methane, we collectively call them Frins says the CFC is chlorofluorocarbons of methane and thene They are called fringes, fringes are so stable Once you've made a Freon Bhai sahib it does not degrade at all, Extremely stable are so unreactive They are non toxic but you do not get any such toxins It's not like you're dying from it It is non-corrosive and easily liquefies You can liquefy these force gases easily can you say freon 12c has two chlorine two fluorine is one of the most common Freon which we use in industrial use use it is manufactured from ccl4 using swats reaction to this Instead of refrigerants, we use ACs etc. I am using it but the problem is that Once you have used no, then your They gradually remain in nature Straight from the atmosphere Well now we're in the stratosphere The chapter has been removed from your syllabus but you Previously taught Environmental Chemistry that they would reach the stratosphere Freon Initiative in the Stratosphere The First Chlorinated Organic The first chlorine based insecticide He made this insecticide Who made it, then why was it not used? What problems occurred the most The point is that you should not use DDT You should know the structure Yes You Need to Know So what is in the structure of DDT? there's a carbon on the carbon there's a hydrogen carbon is attached to a carbon Hydrogen is another carbon on this carbon beyond which there are three chlorines here you have here you have a benzene here you have a benzene here is s here is s it was asked that Tell me how many chiral carbons are there in DDT then you must be seeing that this DDT The carbon that is inside it has these chlorophyll benzene chloro benzene is same then this is not coward this is not coward none of the Carbon is coward so this was your structure Off DDT Done if you are understanding then this was your complete I haven't missed any chapter today More than what was in the chapter I have tried to tell you whichever exam you appear for are you preparing for if you find yourself in I know my bass is bad so HiFi Instead of reading other things read NCERT first If you read NCERT, you will I will gain confidence that I will do it and specifically for boards if you You are thinking that I am just solving 10-12 sample papers. I will do it and go, then everything will be fine for me Look, that is luck as long as the concept You won't know until you see something in the paper If you cannot uproot it then you should know the concept It is important now that I have as much time with you as I can We had as many intake questions as I gave all the examples, I will discuss them now I myself wish that I were not with you people I really want to discuss this exercise as well want me to discuss this exercise but The fun will be there and the benefit will be there once you One will do NCERT exercises by himself Solve NCERT exercises yourself You will literally gain confidence from within ma'am Will this help you in JE Mains or not kids? ok let me give you some clarity I would like to wish that you are studying for NEET Or are you studying NCERT for JE Mains it is compulsory to read it is compulsory it It is important that you read NCERT but Just do this and say that I have got JE Mains will it happen or i will burst it in neet This does not happen because whether NEET is NEET or not JEE Mains ho bit set ho you will get question papers If practice is necessary then it is not so It is correct that he is asking questions from NCERT I make it but you have to practice you will need questions, if you have cleared NEET Practice NEET PYQs for 2018 I did not do JE for which method of JE Questions come if you don't practice them then it will happen from time to time, okay then that If it doesn't help then you need to make sure this So you have to do it after this, whatever exam you take Which exam are you preparing for? Questions about the method come in their practice you have to It will be okay when will the NEET batch of the paid Will you start any paid NEET batch? Means there is no paid batch of NEET right now.
