Ammonia is not a product in the:

Options

A. Hydrolysis of nitrolim
B. Hydrolysis of aluminium nitride
C. Decomposition of ammonium nitrite
D. Hydrolysis of urea

Answer

To determine which process does not produce ammonia, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Hydrolysis of Nitrogen**:
- The reaction for the hydrolysis of nitrogen can be represented as:
\[ N_2 + 3H_2O \rightarrow 2NH_3 \]
- In this reaction, ammonia (NH₃) is produced. Therefore, ammonia is a product in this case.

2. **Hydrolysis of Aluminum Nitride**:
- The reaction for the hydrolysis of aluminum nitride (AlN) is:
\[ AlN + 3H_2O \rightarrow Al(OH)_3 + NH_3 \]
- Here, ammonia is also produced as a product. Thus, ammonia is released in this reaction as well.

3. **Decomposition of Ammonium Nitride**:
- The decomposition of ammonium nitride can be represented as:
\[ NH_4NO_3 \rightarrow N_2 + 2H_2O \]
- In this reaction, nitrogen gas (N₂) and water (H₂O) are produced, but ammonia is not released. Therefore, ammonia is not a product in this case.

4. **Hydrolysis of Urea**:
- The hydrolysis of urea can be represented as:
\[ NH_2CO(NH_2) + H_2O \rightarrow CO_2 + 2NH_3 \]
- In this reaction, ammonia is produced. Hence, ammonia is a product here as well.

### Conclusion:
After analyzing all the options, we find that ammonia is not produced in the **decomposition of ammonium nitride**. Therefore, the correct answer is:

**Option C: Decomposition of Ammonium Nitride.**
