Question

Consider the following statements Phenyl diazonium forms azodye with 1. aniline 2. phenol 3. N, N-dimethylaniline 4. anisole (methoxybenzene) (A) 2,3 and 4 are correct (B) 1,3 and 4 are correct (C) 1,2 and 4 are correct (D) 1,2 and 3 are correct

Ph overset+N≡ N is a weak electrophile that undergoes diazocoupling with rings activated by -OH,-NH2,NHR or -NR2 . The ring is not sufficiently activated by -OCH3 and hence, anisole does not form azodye.

Q. Consider the following statements

Phenyl diazonium forms azodye with

$1.$ aniline

$2.$ phenol

$3.$ N, N-dimethylaniline

$4.$ anisole (methoxybenzene)

$2, 3$ and $4$ are correct

$1, 3$ and $4$ are correct

$1, 2$ and $4$ are correct

$1, 2$ and $3$ are correct

$P h N + \equiv N$ is a weak electrophile that undergoes diazocoupling with rings activated by $- O H, - N H_{2}, N H R$ or $- N R_{2}$ . The ring is not sufficiently activated by $- OC H_{3}$ and hence, anisole does not form azodye.
