Tertiary alcohols and amines

(CH3)3COH is a tertiary alcohol, so why is (CH3)3CNH2 not a tertiary amine?

Grrr. Sometimes we just make it hard for students.

Does your molecule exist? :confused:

If you mean N(CH3)3, then yes it's a tertiary amine.

Whoops, missed a 'C'.

Fixed.

Ah yes I see what you mean... but chemistry would lose some of its charm with a bulletproof system of order imo :biggrin:

The term “tertiary amine” refers to the fact that there are 3 R groups (i.e., not hydrogen) attached to the nitrogen.
(For the alcohol tertiary means that the carbon attached to the -OH has 3 R groups attached)

In your example, the nitrogen is attached to 2 hydrogens and 1 R group so is a primary amine.

Therefore, I think that carboxylic acids should be called primary esters.
