The compound that is explosive in dry state 

Options

A. a. `XeO_3`
B. b. `XeF_6`
C. c. `XeOF_2`
D. d. `XeF_2`

Answer

To determine the compound that is explosive in dry state, we can follow these steps:

### Step 1: Identify the Compounds
We need to consider the compounds of noble gases, particularly xenon oxides, as they are known to exhibit explosive behavior. The relevant compounds include:
- Xenon trioxide (XeO3)
- Xenon tetrafluoride (XeF4)
- Xenon difluoride (XeF2)
- Xenon oxide (XeO)

### Step 2: Analyze the Stability of Each Compound
Among these compounds, we need to assess their stability:
- **XeO3**: This compound is known to be very unstable and can decompose explosively.
- **XeF4** and **XeF2**: These compounds are relatively stable and do not exhibit explosive behavior.
- **XeO**: This compound is also stable and does not show explosive characteristics.

### Step 3: Determine the Oxidation State
Next, we need to consider the oxidation state of xenon in the compounds:
- In **XeO3**, xenon has an oxidation state of +6. This high oxidation state contributes to the instability of the compound.
- In other compounds like XeF4 and XeF2, the oxidation states are lower, which generally leads to more stability.

### Step 4: Conclude the Findings
Based on the analysis, we find that:
- **XeO3** is the compound that is explosive in dry state due to its instability and high oxidation state of xenon.

### Final Answer
The compound that is explosive in dry state is **XeO3**.
