Q. Arrange the following in increasing order of their basic strength?
$p$-nitroaniline $(1)$; m-nitroaniline $(2); 2,6$-trimethylaniline $(3); 3$-methylanline $(4)$.

Amines

Solution:

In case of substituted aniline, electron releasing groups like $-OCH_3, -CH_3$ increase basic strength whereas electron withdrawing groups like $-NO_2, -SO_3H, -COOH, -X$ decrease it.
