Question

Aniline dissolved in dilute HCl is reacted with sodium nitrite at 0º C . This solution was added dropwise to a solution containing equimolar mixture of aniline and phenol in dil. HCl. The structure of the major product is:

Answer 1

Given that,

Aniline dissolved in dilute HCl is reacted with sodium nitrite at 0º C .

We know that,

A solution containing equimolar mixture of aniline and phenol in dil. HCl.

Then,

Aniline undergoes diazo coupling in acidic medium with Phenol $N_{2}^{+}$

We need to find the structure of the major product

Using diagram

$aniline\xrightarrow[0^{\circ}C]{NaNO_{2}+HCl}\text{Phenol} N_{2}^{+}$

Hence, This is required answer.

(C) is correct option.
