MCQ
Among the following, the strongest base is
- A${C_6}{H_5}N{H_2}$
- B$p - N{O_2}{C_6}{H_4}N{H_2}$
- C$m - N{O_2} - {C_6}{H_4}N{H_2}$
- ✓${C_6}{H_5}C{H_2}N{H_2}$
✓
Answer
Correct option: D.
${C_6}{H_5}C{H_2}N{H_2}$
d
$(D)$ is an aliphatic amine; so it is stronger base than aromatic amine.Moreover, EWG $\left(- NO _2\right)$ at $o , p$ and $m$-positions decreases the basic character.The basicity order is:$(D) > (A) > (C) > (B)$.
