Conversion of Benzene into phenylhydrazine

Explanation

To convert benzene into phenylhydrazine, we will follow a series of steps involving specific chemical reactions. Here’s a step-by-step breakdown of the process:

### Step 1: Nitration of Benzene
- **Reaction**: Benzene (C6H6) is treated with a mixture of concentrated nitric acid (HNO3) and concentrated sulfuric acid (H2SO4).
- **Product**: This reaction introduces a nitro group (-NO2) into the benzene ring, resulting in nitrobenzene (C6H5NO2).

### Step 2: Reduction of Nitrobenzene to Aniline
- **Reaction**: Nitrobenzene is then reduced to aniline (C6H5NH2) using a reducing agent such as tin (Sn) in the presence of hydrochloric acid (HCl).
