Question

Among the following, the strongest base is (A) C6H5NH2 (B) p-NO2C6H4NH2  (C) m-NO2-C6H4NH2  (D) C6H5CH2NH2

Lone pair is not taking part in resonance, most basic. In other cases, lone pair of nitrogen is part of delocalisation which decreases Lewis base strength.

Q. Among the following, the strongest base is

$C_{6} H_{5} N H_{2}$

$p - N O_{2} C_{6} H_{4} N H_{2}$

$m - N O_{2} - C_{6} H_{4} N H_{2}$

$C_{6} H_{5} C H_{2} N H_{2}$

Lone pair is not taking part in resonance, most basic. In other
cases, lone pair of nitrogen is part of delocalisation which
decreases Lewis base strength.
