`XeF_6` undergoes thermal decomposition to produce:

Options

A. `XeF_2`
B. `XeF_4`
C. `F_2`
D. All of the above

Answer

To solve the question regarding the thermal decomposition of \( \text{XeF}_6 \), we need to analyze the decomposition reaction and the products formed.

### Step-by-Step Solution:

1. **Understanding the Compound**:
- \( \text{XeF}_6 \) is xenon hexafluoride, a compound of xenon (a noble gas) and fluorine (a halogen).

2. **Thermal Decomposition Reaction**:
- When \( \text{XeF}_6 \) is heated, it undergoes thermal decomposition. This means that the compound breaks down into simpler substances.

3. **Identifying the Products**:
- The thermal decomposition of \( \text{XeF}_6 \) can be represented by the following reaction:
\[ \text{XeF}_6 \rightarrow \text{XeF}_4 + \text{XeF}_2 + \text{F}_2 \]
- From this reaction, we can see that the products formed are:
- \( \text{XeF}_4 \) (xenon tetrafluoride)
- \( \text{XeF}_2 \) (xenon difluoride)
- \( \text{F}_2 \) (fluorine gas)

4. **Conclusion**:
- Therefore, the thermal decomposition of \( \text{XeF}_6 \) produces \( \text{XeF}_2 \), \( \text{XeF}_4 \), and \( \text{F}_2 \).

5. **Selecting the Correct Option**:
- Based on the products formed, the correct answer to the question is:
- **All of the above** (which includes \( \text{XeF}_2 \), \( \text{XeF}_4 \), and \( \text{F}_2 \)).

### Final Answer:
The correct option is **D) all of the above**.
