Convert chlorobenzene to 4- nitrophenol

Explanation

To convert chlorobenzene to 4-nitrophenol, follow these steps:

### Step 1: Hydrolysis of Chlorobenzene
- **Reaction**: Chlorobenzene reacts with sodium hydroxide (NaOH) in the presence of heat.
- **Product**: This reaction leads to the formation of phenol (C6H5OH).

**Chemical Equation**:
\[ \text{C}_6\text{H}_5\text{Cl} + \text{NaOH} \xrightarrow{\text{Heat}} \text{C}_6\text{H}_5\text{OH} + \text{NaCl} \]
