Question

Among the following, the strongest base is

(a) C₆H₅NH₂

(b) p-NO₂C₆H₄NH₂

(c) m -NO_2'C₆H₄NH₂

(d) C₆H₅CH₂NH₂

Answer 1

The correct option is: (d) C₆H₅CH₂NH₂

Explanation:

Benzyl amine (C₆H₅ -- CH₂NH₂ ie, aliphatic amine) with -- NH₂ : group in the side chain behaves like alkyl amines (aliphatic amines) which are more basic as compared with aryl amines which are stabilised due to resonance. On attachment of electron attractive group, basic character is decreased, so benzyl amine is more basic in these amines.
