Explanation

To solve the reaction of benzamide (C₆H₅CONH₂) with nitrous acid (HNO₂), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**: The reactants in this reaction are benzamide (C₆H₅CONH₂) and nitrous acid (HNO₂).

2. **Understanding the Reaction**: The reaction between an amide and nitrous acid leads to the formation of a diazonium salt and the release of nitrogen gas. This is a hydrolysis reaction where the amide is converted into a carboxylic acid.

3. **Formation of Diazonium Salt**: When benzamide reacts with nitrous acid, it first forms a diazonium salt. The structure of the diazonium salt can be represented as C₆H₅C(=O)N₂⁺Cl⁻. Here, the nitrogen from nitrous acid replaces the amine group in benzamide.

4. **Hydrolysis of Diazonium Salt**: The diazonium salt undergoes hydrolysis. In this step, the nitrogen gas (N₂) is released, and the diazonium salt is converted into benzoic acid (C₆H₅COOH).

5. **Final Products**: The final products of the reaction are:
- Benzoic acid (C₆H₅COOH)
- Nitrogen gas (N₂)

### Conclusion:
The products of the reaction C₆H₅CONH₂ + HNO₂ are benzoic acid (C₆H₅COOH) and nitrogen gas (N₂).
