Question

Choose the correct order of the basic nature of the below given amines.
A. Phenyl methanamine
B. N, N-Dimethylaniline
C. N-Methyl aniline
D. Benzenamine

• A. $D>B>C>A$
• B. $D>C>B>A$
• C. $A>C>B>D$
• D. $A>B>C>D$

Answer 1

The correct option is D $A>B>C>D$

Lone pair of N on compound (A) is localised. So, it is more basic whereas lone pair of N in other compounds are delocalised in the benzene ring so they are less basic.
Comparing B, C and D, B has more basic nature due to the presence of two +I group (Methyl) follwed by (C) which has one +I group. D has least basic nature.

Hence, correct answer is (d).
