AAMC 5R bio question

[UCLAstudent]

I'd post this in the "questions" thread, but I don't want to spoil it for anyone else who has taken it.

For problem 172, my answer key says that the answer is A (primary amines). I don't see how that is possible. Looking at the picture in the passage, I can see how benzylamine is a primary amine because the N is bound to a carbon that is only bound to one other carbon. For aniline, it is bound to a carbon bound to two other carbons. Wouldn't that make it secondary? I think maybe I am mixing up the rules for classifying alcohols with classifying amines.

It is the number of Carbons the N is attached to directly... not the number of Carbons the carbon N is attached to is attached to... wow that could probably be reworded but I'm sure you get what I'm saying...

Thank you, you're wonderful!

yep in amines it is little different..... it is the number of Cs directly bonded to N that counts.

 

[farley is god]

that also tripped me up on that particular problem.

damn organic chemists.
