Which is used as hydrogen generators

Options

A. NaH
B. HI
C. `S_(6)H_(3)`
D. None of these

Explanation

To determine which compound is used as a hydrogen generator, we need to analyze the options provided: NH, HI, S6, H3, and none of these.

### Step-by-Step Solution:

1. **Understanding Hydrogen Generation**:
Hydrogen can be generated through various methods, one of which is electrolysis, where water is split into hydrogen and oxygen.

2. **Evaluating the Options**:
- **NH (Sodium Hydride)**: This is a metal hydride that can react with water to produce hydrogen gas.
- **HI (Hydriodic Acid)**: This is a strong acid but does not serve as a hydrogen generator in the same way as metal hydrides.
- **S6**: This is not a relevant compound for hydrogen generation.
- **H3**: This is not a standard representation of a compound that generates hydrogen.
- **None of these**: This option implies that none of the provided compounds are suitable.

3. **Analyzing Sodium Hydride (NAH)**:
Sodium hydride (NaH) reacts with water as follows:
\[ \text{NaH} + \text{H}_2\text{O} \rightarrow \text{NaOH} + \text{H}_2 \]
In this reaction, sodium hydride reacts with water to produce sodium hydroxide and hydrogen gas.

4. **Conclusion**:
Based on the analysis, the most suitable option for a hydrogen generator among the given choices is **NaH (Sodium Hydride)**.

### Final Answer:
**NaH (Sodium Hydride)** is used as a hydrogen generator.
