Solution
The correct option is D N-Ethylethanamine
Primary amines are formed when one hydrogen atom in ammonia is substituted by an alkyl or aromatic group. Secondary amines are those amines that have two organic substituents either alkyl or aryl ones or both. They are bound to the nitrogen together with one hydrogen. Tertiary amines are those where the nitrogen consists of three organic substituents.
Diphenylamine is aromatic secondary amine. N atom is attached to two aryl groups and one H atom.
In N-Ethylethanamine N atom is attached to two alkyl groups and one H atom.
Thus, (a) and (d) are secondary amines.
