A. Phenyl methanamine B. N,N-Dimethylaniline C. N-Methylaniline D. Benzenamine Choose the correct order of basic nature of the above amines:

1. A > C > B > D
2. D > C > B > A
3. D > B > C > A
4. A > B > C > D

Correct answer: A > B > C > D

Solution

Benzylamine (A) is an aliphatic-type amine and most basic. Among the anilines, more N-alkyl groups raise basicity in water: N,N-dimethylaniline (B) > N-methylaniline (C) > aniline (D). Hence A > B > C > D.
