A compound which on hydrolysis releases ammonia is-

Options

A. `Li_(3)N`
B. `LiNO_(3)`
C. `NaNO_(3)`
D. None of these

Answer

To solve the question "A compound which on hydrolysis releases ammonia is-", we will analyze the options and determine which compound, when hydrolyzed, produces ammonia (NH3).

### Step-by-Step Solution:

1. **Understanding Hydrolysis**: Hydrolysis is a chemical reaction involving the breaking of a bond in a molecule using water. In this case, we are looking for a compound that produces ammonia when it reacts with water.

2. **Identifying Possible Compounds**: We need to consider compounds that are known to release ammonia upon hydrolysis. One such compound is lithium nitride (Li3N).

3. **Chemical Reaction of Lithium Nitride**:
- When lithium nitride (Li3N) undergoes hydrolysis, it reacts with water (H2O) to produce lithium hydroxide (LiOH) and ammonia (NH3).
- The balanced chemical equation for this reaction is:
\[ \text{Li}_3\text{N} + 3\text{H}_2\text{O} \rightarrow 3\text{LiOH} + \text{NH}_3 \]

4. **Oxidation States**:
- In lithium nitride, lithium (Li) has an oxidation state of +1 and nitrogen (N) has an oxidation state of -3.
- This means that in Li3N, the nitrogen is in a state that allows it to release ammonia upon hydrolysis.

5. **Conclusion**: Since lithium nitride (Li3N) is the compound that releases ammonia when hydrolyzed, we conclude that the correct answer is option A: Li3N.

### Final Answer:
The compound which on hydrolysis releases ammonia is **Li3N**.
