A salt of cellulose used in propellent explosives is

Options

A. Cellulose acetate
B. Cellulose nitrate
C. Cellulose superphosphate
D. Cellulose hypoxanthate.

Answer

To solve the question about the salt of cellulose used in propellant explosives, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Cellulose**:
- Cellulose is a polysaccharide made up of β-glucose units linked together by β(1→4) glycosidic bonds. It is a major component of the plant cell wall and is not soluble in water.

**Hint**: Remember that cellulose is a structural polysaccharide found in plants.

2. **Identify the Options**:
- The options given are:
- Cellulose acetate
- Cellulose nitrate
- Cellulose superphosphate
- Cellulose hypoxanthate

**Hint**: Look for the chemical modifications of cellulose that could relate to explosive properties.

3. **Analyze Each Option**:
- **Cellulose Acetate**: This is a derivative of cellulose where some hydroxyl groups are converted into acetate groups. It is used in photography and as a film base but not as an explosive.
- **Cellulose Nitrate**: Also known as nitrocellulose, this compound is formed by the nitration of cellulose using nitric acid. It is known for its explosive properties and is used in propellant explosives.
- **Cellulose Superphosphate**: This is a fertilizer and does not have explosive properties.
- **Cellulose Hypoxanthate**: This is not commonly associated with explosives.

**Hint**: Focus on the chemical modifications that lead to explosive characteristics.

4. **Determine the Correct Answer**:
- Based on the analysis, cellulose nitrate (nitrocellulose) is the compound that is used as a propellant explosive.

**Hint**: Recall that nitrocellulose is specifically known for its use in explosives.

5. **Conclusion**:
- The correct answer to the question is **cellulose nitrate**.

### Final Answer:
The salt of cellulose used in propellant explosives is **cellulose nitrate**.
