Question
**Propose a mechanism for the reaction shown below.**

**a)**

The reaction involves the conversion of a chlorobenzene derivative into a phenol derivative under the influence of the amide ion (\(\Theta \text{NH}_2\)) and heat.

- **Reactant**: The starting material is a para-nitrochlorobenzene, with a nitro group (\(\text{NO}_2\)) at the para position to a chlorine atom (\(\text{Cl}\)) on the benzene ring.
- **Reagent**: \(\Theta \text{NH}_2\) and heat.
- **Product**: The resulting product is a para-nitrophenol, with a hydroxyl group (\(\text{OH}\)) replacing the chlorine atom on the benzene ring and a chloride ion (\(\text{Cl}^-\)) as a side product.

**b)**

This reaction is a nitration process, where benzene is converted to nitrobenzene.

- **Reactant**: Benzene.
- **Reagents**: Nitric acid (\(\text{HNO}_3\)) and sulfuric acid (\(\text{H}_2\text{SO}_4\)).
- **Product**: Nitrobenzene, with a nitro group (\(\text{NO}_2\)) added to the benzene ring.

This educational content assists in understanding aromatic substitution reactions, demonstrating the conversion of aromatic compounds through nucleophilic and electrophilic aromatic substitution mechanisms.
