Which of the following compounds produces only basic product(s) on hydrolysis ?

Options

A. `Mg_(3)N_(2)`
B. `NCl_(3)`
C. `B Br_(3)`
D. `LiH`

Answer

To determine which of the given compounds produces only basic products upon hydrolysis, we can analyze each compound one by one.

### Step-by-Step Solution:

1. **Identify the Compounds**: We have four compounds to analyze. For this solution, let's denote them as:
- Compound A: Mg3
- Compound B: NCl3
- Compound C: NH4OH
- Compound D: (another compound not specified in the transcript)

2. **Analyze Hydrolysis of Each Compound**:
- **Compound A (Mg3)**:
- When magnesium nitride (Mg3) undergoes hydrolysis, it reacts with water (H2O) to produce magnesium hydroxide (Mg(OH)2) and ammonia (NH3).
- Reaction:
\[ Mg_3 + 6H_2O \rightarrow 3Mg(OH)_2 + 2NH_3 \]
- Both products (Mg(OH)2 and NH3) are basic in nature.

- **Compound B (NCl3)**:
- Hydrolysis of nitrogen trichloride (NCl3) with water produces hydrochloric acid (HCl) and ammonia (NH3).
- Reaction:
\[ NCl_3 + 3H_2O \rightarrow NH_3 + 3HCl \]
- HCl is acidic, so this compound does not produce only basic products.

- **Compound C (NH4OH)**:
- Ammonium hydroxide (NH4OH) is already a basic solution, but when it hydrolyzes, it does not produce only basic products.
- Hydrolysis does not yield additional basic products; it remains as NH4OH in solution.

- **Compound D**:
- (Assuming it is another compound not specified, we will skip this for now as per the transcript).

3. **Conclusion**:
- From our analysis, only **Compound A (Mg3)** produces only basic products upon hydrolysis. The products are magnesium hydroxide (Mg(OH)2) and ammonia (NH3), both of which are basic.

### Final Answer:
The compound that produces only basic products on hydrolysis is **Compound A (Mg3)**.
