Options

B. `R-NH_(2)`
C. `RCH_(2)NH_(2)`
D. `RCOCH_(2)NH_(2)`

Explanation

To solve the question regarding the treatment of acyl azide (RCON₃) with acidic or alkaline medium, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Acyl Azide Structure**:
- Acyl azide can be represented as RCON₃, where R is an alkyl or aryl group. The structure consists of a carbonyl group (C=O) attached to a nitrogen group (N₃).

2. **Reaction with Acidic or Alkaline Medium**:
- When acyl azide is treated with an acidic or alkaline medium, the azide group (N₃) undergoes decomposition. This results in the loss of nitrogen gas (N₂).

3. **Formation of Intermediate**:
- The reaction leads to the formation of an intermediate, which can be represented as R-C(=O)-N. Here, the nitrogen from the azide group is now bonded to the carbonyl carbon.

4. **Hydrogenation of the Intermediate**:
- If hydrogen gas (H₂) is present, the intermediate can further react. The double bond between the carbon and nitrogen can be reduced, leading to the formation of an amine.

5. **Final Products**:
- The final products of this reaction are:
- RNH₂ (primary amine)
- CO₂ (carbon dioxide) as a byproduct from the breakdown of the carbonyl group.

### Conclusion:
- Therefore, the treatment of acyl azide (RCON₃) with acidic or alkaline medium yields RNH₂ (a primary amine) as the main product.
