Question

The strongest base among the following is

A. $${C_6}{H_5}N{H_2}$$
B. $$p{\text{ - }}N{H_2}{C_6}{H_4}N{H_2}$$
C. $$m{\text{ - }}N{O_2}{C_6}{H_4}N{H_2}$$
D. $${C_6}{H_5}C{H_2}N{H_2}$$  
Answer :   $${C_6}{H_5}C{H_2}N{H_2}$$
Solution :
$${C_6}{H_5}C{H_2}\ddot N{H_2}$$    is the strongest base since the lone pair on nitrogen is not involved in conjugation.
