Which of the following dissolves in water but does not give any oxyacid solution? 

Options

A. `SO_2 `
B. `OF_2`
C. `SCl_4`
D. `SO_3`

Answer

To solve the question "Which of the following dissolves in water but does not give any oxyacid solution?", we will analyze each of the given compounds to see if they form oxyacids upon dissolving in water.

### Step-by-Step Solution:

1. **Identify the Compounds**: We have four compounds to analyze: SO2, OF2, SCl4, and SO3.

2. **Analyze SO2**:
- When SO2 (sulfur dioxide) dissolves in water, it reacts to form H2SO3 (sulfurous acid).
- **Conclusion**: SO2 gives an oxyacid (H2SO3).

3. **Analyze OF2**:
- OF2 (oxygen difluoride) dissolves in water and reacts to form HF (hydrofluoric acid) and O2 (oxygen).
- **Conclusion**: HF is not considered an oxyacid because it does not contain oxygen in the form of an oxoacid structure. Therefore, OF2 does not give an oxyacid solution.

4. **Analyze SCl4**:
- SCl4 (sulfur tetrachloride) reacts with water to produce H2SO3 and HCl (hydrochloric acid).
- **Conclusion**: SCl4 gives an oxyacid (H2SO3).

5. **Analyze SO3**:
- SO3 (sulfur trioxide) reacts with water to form H2SO4 (sulfuric acid).
- **Conclusion**: SO3 gives an oxyacid (H2SO4).

6. **Final Conclusion**:
- From the analysis, SO2, SCl4, and SO3 all produce oxyacids when dissolved in water.
- The only compound that dissolves in water but does not produce an oxyacid is OF2.

### Answer:
The compound that dissolves in water but does not give any oxyacid solution is **OF2**.
