Options

A. Ionic
B. covalent
C. Coordinate covalent
D. Metallic

Answer

To solve the question regarding solid \( N_2O_5 \), we need to analyze the information given and determine the nature of the solid based on x-ray diffraction data.

### Step-by-Step Solution:

1. **Understanding the Compound**:
- The compound in question is \( N_2O_5 \), which is known as dinitrogen pentoxide.

2. **Analyzing the Structure**:
- According to the x-ray diffraction data mentioned, solid \( N_2O_5 \) dissociates into \( NO_2 \) (nitrogen dioxide) and \( NO_3^- \) (nitrate ion).

3. **Identifying the Ions**:
- The presence of \( NO_2 \) and \( NO_3^- \) suggests that the solid \( N_2O_5 \) can be represented in terms of its ionic components.

4. **Determining the Nature of the Solid**:
- Since \( N_2O_5 \) can be broken down into ions, this indicates that it has ionic characteristics. Ionic compounds typically consist of positively and negatively charged ions.

5. **Conclusion**:
- Therefore, based on the x-ray diffraction data and the decomposition into ions, we conclude that solid \( N_2O_5 \) exists in an ionic form.

### Final Answer:
Solid \( N_2O_5 \) exists in the form of \( NO_2 \) and \( NO_3^- \), indicating that it is ionic in nature.
