you are the best. I love you Khan academy :*****

Thank you soooo muchh!!!..........from Morocco

Made it easy thank u

Thank you!

Can anyone tell me why the cyclohexane isnt a heptane starting with one of the methyl groups and then working round?

+Luko B you have to look at each point as a carbon basically i know this is a late response

If the molecule has no other functional groups that use a suffix (at the end of the name) we use "amino" at the end. However, if there is a more important functional group which would use a suffix as part of its name we take te amino and use it as a prefix instead (at the start of the name).

Quiet interesting and I have learnt

at 06:18, can the compound be named as 3-ethoxy-1-methyl-cyclohexanamine?? plz help...

IUPAC naming conventions give priority to having the lowest substituent numbers. While you want to give the ethoxy group a low number (3) you can get an even smaller number (2) by naming the methyl group first.

would that mean benzamide is a primary amine?

Naming first is a good thing. Structure comes in an easier way. Keep on going.

I thought primary/secondary/tertiary amines were based on the amount of carbons that the amine carbon was attached to. So like NH2-CH3= primary. CH3 CH (NH2) CH3= secondary because the NH2 is attached to the second carbon, which intern is attached to 2 other carbons. And CH3 CH (CH2) (NH2) CH3 = primary because NH2 is attached to the second carbon, but so is a methyl group. So the second carbon is attached to 3 other carbons.

sorry this is a late reply but I see where you got confused. It's about how many alkyl groups the N on the amine is attached to. So NH2-CH3 = primary. CH3CH(NH2)CH3 = primary as there is one alkyl group attached to the N, but you name it using the no of the C it is attached to: 2-aminopropane. CH3CH(CH2)(NH2)CH3 = primary as the N is attached to 1 alkyl group. This would be called 2-methylpropylamine. A trick is, if the amine's structural formula has NH2, it is primary; if it has NH, it is secondary; if it is N it is tertiary, because the H have been replaced by alkyl groups.

I LOVE YOU!!!!!

speed 1.5 ftw, great idea

why dont u put "e" after heptane?its just an alkane right?so,,,?

Can I name it like this? 2- heptanamine

Can the second compound be called 3 ethoxy -1,6 dimethyl cyclohexanamine?

IUPAC naming conventions want the lowest numbers for the substituents.

What`s the name of this program ?

I don't think so. It is my understanding that alcohols have the highest priority of all the functional groups in terms of giving it the lowest number, followed by amines, and then followed by ethers. So ethers actually have one of the lowest priorities out of all the functional groups out there. Furthermore, in the case of a double bond (alkene) or triple (alkyne) you would number so the double bond or triple gets the lowest number. If its a tie, the double bond gets priority over triple

shouldn't the ethoxyde have more priority then the methyl group on #2 and change the cyclo order, and therefore it would be 3-ethoxy and 1,6-dimethyl?

Andre Fontes no you number to the closest branch to 1 , 2 would be closer than 3 so you number clockwise

Hello:) my teacher always uses the prefix amino to name compounds that have the amine functional group as its primary function , for example he would say ... 3-aminodecane .... instead of how you would say it which would be decan-3-amine ... is there a right or wrong way ??? i'm a bit confused ... it would be great if you could answer this! btw i love your videos:) they are very good!!

So how do you know its a methyl-group if its not noted?

no, amines have higher functional group than alkanes

I don't think the priority of the substituent matters after you figure out which one is the top priority one. You're only trying to number so that the substituents get the lowest number. 1,2,5 would be lower than 1,3,6 so that's why it's not 3-ethoxy-1,6-dimethylcyclohexanamine.

candykitty52 You're right, if there is more than two substituents , the lowest number priority is above substituent group priority

I thought Carboxyl groups were the highest priority functional group.
