On heating sodium metal in a current of dry ammonia, the compound formed is

Options

A. sodium imide
B. sodium nitride
C. sodium amide
D. sodium azide

Answer

To solve the question regarding the compound formed when sodium metal is heated in a current of dry ammonia, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Reactants**:
- We have sodium metal (Na) and dry ammonia (NH3) as the reactants.

2. **Identifying the Reaction**:
- When sodium metal reacts with ammonia, it can lead to the formation of sodium amide (NaNH2) and hydrogen gas (H2).

3. **Writing the Balanced Chemical Equation**:
- The reaction can be represented as:
\[ 2 \text{Na} + 2 \text{NH}_3 \rightarrow 2 \text{NaNH}_2 + \text{H}_2 \]
- This equation shows that two moles of sodium react with two moles of ammonia to produce two moles of sodium amide and one mole of hydrogen gas.

4. **Identifying the Product**:
- From the balanced equation, we can see that the primary product formed is sodium amide (NaNH2).

5. **Conclusion**:
- Therefore, the compound formed when sodium metal is heated in a current of dry ammonia is sodium amide.

### Final Answer:
The compound formed is **Sodium Amide (NaNH2)**.
