If, Aniline →ii)H2O,Δi)NaNO2+HCL,273K\xrightarrow[ii)H_2O, \Delta]{i)NaNO_2+HCL, 273K} Product

Identify the product of above reaction.

A

o-Nitroaniline

B

m-Nitroaniline

C

p-Nitroaniline

D

Phenol

Answer

Phenol

Explanation

Solution

  1. Step 1: Formation of Diazonium Salt

    Aniline is treated with NaNO₂ and HCl at 273K to form the benzenediazonium chloride.

  2. Step 2: Hydrolysis

    When the diazonium salt is warmed with water (Δ), it undergoes hydrolysis to yield phenol.

Aniline → diazonium salt (via NaNO₂/HCl) → hydrolysis → phenol.
