Electrolytic reduction of nitrobenzene in weakly acidic medium gives .

Options

A. Aniline
B. p-Hydroxy aniline
C. N-Phenyl hydroxyl amine
D. Nitroso benzene

Answer

To solve the question regarding the electrolytic reduction of nitrobenzene in a weakly acidic medium, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Reaction**: The electrolytic reduction involves passing an electric current through nitrobenzene, which is a compound containing a nitro group (-NO2) attached to a benzene ring.

2. **Identify the Medium**: The question specifies a weakly acidic medium. This means that the presence of acid will facilitate the reduction process, but it is not as strong as in a strongly acidic medium.

3. **Know the Products**: The possible products given are:
- Aniline (C6H5NH2)
- p-Hydroxyaniline (C6H4(OH)(NH2))
- N-Phenyl hydroxylamine (C6H5NHOH)
- Nitrosobenzene (C6H5NO)

4. **Electrolytic Reduction Process**: In weakly acidic conditions, the nitro group (-NO2) in nitrobenzene is reduced to an amino group (-NH2). The reduction process typically converts nitrobenzene directly to aniline.

5. **Final Product**: Therefore, the main product formed from the electrolytic reduction of nitrobenzene in a weakly acidic medium is **aniline (C6H5NH2)**.

### Conclusion:
The answer to the question is **aniline**.
