Options

A. `NCl_3`
B. `N_2 O_5`
C. `NH_3`
D. `NF_3`

Explanation

To solve the question "A compound of nitrogen which is explosive is," we need to analyze the options provided and identify which nitrogen compound is known for its explosive properties.

### Step-by-Step Solution:

1. **Identify the Compounds**:
- The question mentions a compound of nitrogen that is explosive. The options given include NCl3 (Nitrogen Trichloride), N2O5, ammonia (NH3), and NF3.

2. **Analyze Each Compound**:
- **NCl3 (Nitrogen Trichloride)**: This compound is known to be explosive and is formed by the reaction of ammonia (NH3) with chlorine (Cl2).
- **N2O5**: This compound is primarily used as a nitrating agent and oxidizer in high-fuel rockets but is not classified as an explosive in the same sense as NCl3.
- **Ammonia (NH3)**: While ammonia has various uses, it is not explosive.
- **NF3**: This compound is used in the manufacture of semiconductors and LCDs but is not known for explosive properties.

3. **Conclusion**:
- Among the options, NCl3 (Nitrogen Trichloride) is the compound of nitrogen that is explosive.

### Final Answer:
The compound of nitrogen which is explosive is **NCl3 (Nitrogen Trichloride)**.
