hello and welcome to my channel in this video I'm going to be showing you how to identify primary secondary and tertiary carbons so for this particular compound if you are asked to identify the primary carbon the secondary carbon and the tertiary carbon this carbon for example the primary carbon we have only one other carbon connected to it one other carbon connected to it so in this case this carbon here has only one carbon which is this connected to it okay so we say that this carbon is primary and when we do primary we use like one degree to represent that so that carbon is a primary carbon whatever is attached to a primary carbon will then be primary so if you have hydrogens attached to a primary carbon you have a primary hydrogen okay so this is a primary hydrogen if you have an alcohol attached for example if we had o attached to that this would then be a primary alcohol okay now if we move on to this other carbon it's attached to one and then two so it's attached to two other carbon two other carbons that makes this carbon a secondary carbon if you have anything attached to it so for example if you also have an alcohol attached that makes it a secondary alcohol okay now if we move to this other one which I'm going to use another color to represent so for this one here it is attached to one carbon here another carbon here and the third Carbon on my right which means that this carbon is connected to three different carbons and that makes this carbon a tertiary carbon okay so whatever is attached to this particular carbon so for example this hydrogen is going to be a tertiary hydrogen and if we change that hydrogen to something else to probably an IM so it could be let's say this was changed to nh2 that would then become also a tertiary Im so whatever is attached to the carbon that is tertiary becomes tertiary as well okay and finally this one here is going to be is only connected to one so that is Prim okay so that is how you can identify a primary carbon is secondary carbon a tertiary carbon so as a recap if you have the carbon connected to one other carbon that would be primary if you have the carbon connected to two other carbons that will be secondary if you have the carbon connected to three other car that will be tertiary and whatever is connected to that carbon the primary carbon whatever is attached to it be it an alcohol hydrogen amine Amite and so on is going to become the same as the carbon now let's look at the line structure now they give us this line structure and they're asking us to identify the primary secondary and tertiary okay so this is a carbon this is a carbon this is a carbon that's a carbon this is a carbon and this is a carbon so this carbon here is connected to only this carbon which makes this carbon primary okay now this number one carbon is connected to only this carbon and and this one so it's connected to one and two so this makes it a secondary carbon this one here is connected to one and then two that makes this one a secondary carbon then this one here is connected to 1 2 and three that makes this one a tertiary carbon then this here is connected to only this one that makes that a primary carbon this is also connected to only this that makes it a primary C and that is how you can figure out the primary secondary and tertiary on a line structure I hope this has helped you to learn how to identify primary secondary and tertiary thank you for watching and see you in my next video bye
