What is the Basis for Classifying Amines as Primary, Secondary

Question

What is the basis for classifying amines as primary, secondary, or tertiary?
A) the number of carbons bonded directly to a nitrogen atom
B) the number of carbons bonded to a carbon that is also bonded to nitrogen
C) the number of nitro groups bonded directly to a nitrogen atom
D) the number of hydrogen atoms present in the alkyl groups of an amine

Accepted Answer

The classification of amines as primary, secondary, or tertiary is based on the number of carbon atoms directly bonded to the nitrogen atom. In primary amines, one carbon is bonded to nitrogen; in secondary amines, two carbons are bonded to nitrogen; and in tertiary amines, three carbons are bonded to nitrogen.
