Write chemical equations for the following conversion :
(i) Nitrobenzene to benzoic acid.
(ii) Benzyl chloride to 2-pheylethanamine .
(iii) Aniline to benzyl alcohol.

Explanation

To solve the conversions mentioned in the question, we will write the chemical equations step by step for each conversion.

### (i) Conversion of Nitrobenzene to Benzoic Acid

1. **Reduction of Nitrobenzene to Aniline**:
- Nitrobenzene (C6H5NO2) is reduced to Aniline (C6H5NH2) using Sn (tin) and HCl.
\[
\text{C}_6\text{H}_5\text{NO}_2 + 3\text{H}_2 \xrightarrow{\text{Sn/HCl}} \text{C}_6\text{H}_5\text{NH}_2 + 2\text{H}_2\text{O}
