Mnemonic Techniques for Name Reactions

trick to learn name reactions in organic chemistry I will teach you my personal take to learn 20 name reactions in organic chemistry in a very short time firstly let me teach you five reactions using my personal track I write world food rwf I A W plus F which is WF now listen carefully this W stands for Words reaction this F stands for fatigue reaction and this WF stands for Words fatigue reaction now think about a very unique girl in your school or college let her name is Roxana boxana she loves to eat dried eggs remember that I capitalize every second letter of Roxanna buxana now in case a force reaction I take R and X it is alkyl halide noted down that here x is halogen like chlorine bromine Etc secondly I take an air which is sodium thirdly I take this RX and I write it again after sodium note it down that if we know the reactants we can easily guess the products so here sodium will react with these two eggs are halogens and we will get two sodium halide this R and this are will combine together to form alkane this dried eggs stands for dry ether thus this is the worst reaction now in case of fatigue reaction I consider boxana this B and buxana stands for Benzene ring and this x are halogen is attached to eight plus this NS stands for sodium plus I take this Benzene and x i rewrite it here now sodium will react with these two halogen to form two sodium halide plus this Benzene and this Benzene ring joined together to form diphenyl this stride X stands for dry eater thus this is the fatigue reaction thirdly in case of words fatigue reaction I write sodium I take the first reactant from Force reaction and first reactants from fatigue reaction we know that sodium will react with these two halogenes I get two sodium halide this Benzene ring and this alkyl joined together to form alkyl Benzene this dried egg stands for dry ether thus this is the world's fatigue reaction thus using this trig we can easily learn these three reaction fourthly this F also stands for Finkle stain reaction now let's consider the sister of Roxana buxana let the name of her sister is rukhsana India she loves to eat dry Apple remember that I again capitalize every second letter in the rukhsana India now as usual I take rnx then I take sodium this I in India stands for iodine IE we know that metal like sodium loves to react with this halogen so we get sodium halide plus alkyl iodide this dry apples mean dry acetone so this is the complete reaction of Finkle stain reaction fifthly consider Swartz reaction remember that in this word I select s a r now this SAR reminds me Switzerland flag this r and Switzerland remind me Rx now the AG and the flag reminds me AG are silver F and the flag reminds me f fluorine we know that metal like silver react with halogen X to form silver halide while this fluorine and alkyl combine together to form alkyl fluoride so this is the Schwarz reaction thus noted down this five reaction which are somehow connected now let me teach you two more reactions like send me reactions and get your main reaction now and sand beer there is word Mayor we know that mayor controls a specific area like a town Bazaar Etc let here the mirror is Mr najam so I say closed custom Bazaar let me repeat it closed custom Bazaar this close reminds me close structure of benzene this n energy stands for nitrogen gas N2 remember that I need to put halogen after every element this CL enclosed stands for chlorine now this Co and custom stands for copper I again need to put one halogen like chlorine this BR and Bazaar stands for Bromine we know that beer does not exist independently I put hydrogen with it so these are the reactants of this reaction now we can easily guess its products I cut hydrogen andromine I cut nitrogen and chlorine this nitrogen gas will evolve as nitrogen gas this chlorine and Edge combine to form HCL this Benzene and bromine reacts together to form alkyl halide so this is the senior reaction what about getter main reaction well I rewrite the same mere reaction now listen carefully I cut only copper chloride and replace it with copper powder let me repeat it I cut only copper chloride and replace it with copper powder I get gutter main reaction so this is the gutter main reaction the snotted down these two reactions now I will teach you two more reactions I write K Rahul team remember the famous cricketer k l Rahul here this K stands for Colby's reaction and this rnt stands for rimmer Demon's reaction now listen carefully this o and Colby stands for o h and carbon dioxide this b stands for Benzene and bass plus salt thus I take this o h and I attach it to Benzene ring I get phenol secondly I write carbon dioxide the base is sodium hydroxide and the acid is HCl these are the reactions of this reaction and we can easily guess its products I take this phenyl and I write it here now I select this carbon dioxide and H of Base lastly I attach C double o h to this Benzene ring I get salicyclic acid so this is the Colby's reaction in case of reamer Demon's reaction I rewrite the above reaction now listen carefully I cut this O2 and this oxygen of C double o h i replace only the O2 by cl3 let me repeat it I cut this O2 and this o of C double o h i replace only this O2 by cl3 we get a new substance and we call it salicyl aldehyde thus this is the Reimer Demon's reaction now let me teach you Williamson synthesis this on in Williamson reminds me Ronaldo Reyes this r-o-n-a is sodium alkoxide these are enres stands for RX alkyl halide these are the reactants of this reaction now sodium being positive will attack on halogen we get sodium halide this Ro and this are combined together to form ether so this is the Williamson synthesis reaction now let me teach you stiffen reduction reaction well I select r c and N in reduction now this RC and n stands for alkyl Cyanide now these are the three letters s123 I write here three dashes now I select s and n and Stefan it stands for sncl2 Artin chloride this stash is for acid like HCL and this Dash is for water these are the reactants of this reaction I replace this nitrogen by h o of water I write RC and H O this is aldehyde so this is the stiffen reduction reaction now let me teach you a charge reaction well this tea and it hard reaction reminds me tolene so I write tolene which is ch3 plus Benzene ring secondly this e reminds me Elon Musk we know that he is crazy and clever the CR in Crazy stands for chromium oxide and this CL and clever stands for chlorine these are the reactants of this reaction now I replace these three by oxygen I write CH plus Benzene ring and I attach oxygen to it Highgate Ben's aldehyde so this is the itard reaction now let me teach you half man bromide reaction well I select n a and o h and half man I write it as sodium hydroxide plus I select Brom and Rome Amite I write bromine thirdly I select amide and brome Amite we know that Amite is R Dash c o dash nh2 so these are the reactants of this reaction now I break sodium and hydroxide I break R Co and nh2 sodium will attack on BR and Co I get sodium bromide plus sodium carbonate this R nh2 will combined together to form a mine so this is the half man from amide reaction this noted down now let me teach you two more reactions like friedel crafts alkylation and friedel crafts essilation well I always count the words of crafts one two three four five six these six letters remind me the six carbon of benzene ring so I write here Benzene rain secondly this A and L in alkylation reminds me a lcl3 aluminum chloride so I write here aluminum chloride thirdly alkylation means alkyl halide like ch3cl so I write here ch3cl these are the reactants of this reaction thus I can easily guess its product now I cut CL and I attach the ch3 to Benzene ring I get tolene this is the friedel crafts alkylation in case of reader crafts escalation I take Benzene and hcl3 and I write them here know the word escalation means like ch3cocl I write here ch3cocl we know that here we cut CL similarly I also cut here CL I take Benzene and I write it here lastly I go from back to right ch3co I mean I write Co and then ch3 I get a set of phenon this is the freedom crafts escalation so note it down these two reactions now let me teach you carbile a mind reaction well in carbile a mine I select C and B the C stands for Chloroform its formula is chcl this b stands for base like sodium hydroxide secondly I select a mine the formula of a mind is R nh2 so these are the reactants of this reaction now this will displace this H2 I get R and C we call this compound as isocyanide also this K will attack on chlorine to form potassium chloride remember that this reaction is only possible in case of primary amine or one degree a mine like ch3ch2 nh2 it is not possible in secondary and terrestrial Amine let me teach you hvc reaction well this H and hvc always reminds me Alpha hydrogen is displaced now what is Alpha hydrogen I write carboxylic acid group like C double o h i attach one carbon and one alkyl to eight now this adjacent carbon or second carbon after this carbon is called Alpha carbon and the hydrogen attached to it is called Alpha hydrogen secondly I write a red powder in chlorine water this rate and P of powder stands for red phosphorus CL stands for chlorine gas and water is H2O these are the reactants of this reaction we already know that Alpha hydrogen is displaced so this chlorine will displace one alpha hydrogen I rewrite the compound in case of one alpha hydrogen I write chlorine to Alpha carbon remember that this reaction is used for the halogenation of carboxylic acid now let me teach you two more reactions clemency reduction reaction and wolf Kushner reduction reaction now listen carefully in the clemensen there is a word Sun we know that every Sun needs a coach remember that I write here c o and I write Dear ch similarly I write here c o and I write Dear ch this Co is the reactant and this CH is the product also this Co is the reactant and this CH is the product now what about the other reactants of clemension reaction well this CL reminds me HCL so I write here HCL secondly this mm reminds me a zigzag line here this Z stands for zinc and G stands for HG so I write here zinc and HG this is the complete Clementine reaction now what about the other reactants of wolf Krishna reduction reaction well this K and kishner reminds me potassium hydroxide I write here potassium hydroxide secondly I select this n and H it reminds me nh2 nh2 so I write here nh2 NH H2 this is the complete wolf kishner reduction reaction remember that in this both reactions we convert Ketone to aldehyde this noted down these two reactions lastly let me teach you get a man coach reaction now this Guitar Man reminds me guitar man I always say guitar man brings Elko Hull let me repeat it I always say guitar man brings alcohol now this B ring stands for Benzene ring this ALC stands for aluminum chloride the co stands for Co and this h a l stands for HCL so I write here Benzene ring I write here aluminum chloride Co and then HCL these are the reactants of this reaction now I select Co and H and I add a to the Benzene ring I write here Benzene ring and I attach coh to it I get pens aldehyde so this is the complete Gutterman coach reaction thus noted down all these 20 reactions and try to practice them every day for a week I hope that you will learn all these 20 reactions
