How is phenol obtained from aniline ?

Explanation

To obtain phenol from aniline, we can follow a series of chemical reactions involving diazotization and hydrolysis. Here’s a step-by-step breakdown of the process:

### Step 1: Diazotization
1. **React aniline with sodium nitrite (NaNO2) and hydrochloric acid (HCl)** at a low temperature (0 to 5 degrees Celsius).
- This reaction converts aniline (C6H5NH2) into benzenediazonium chloride (C6H5N2Cl).
- The reaction can be represented as:
\[
C6H5NH2 + NaNO2 + HCl \rightarrow C6H5N2Cl + NaCl + 2H2O
