Assertion:- `SF_(6)` cannot be hydrolysed but `SF_(4)` can be.
Reason:- Six F atoms in `SF_(6)` prevent the attack of `H_(2)O` on sulphur atom of `SF_(6)`

Options

A. Both Assertion and Reason are correct statements , and Reason is the correct explation of the Assertion.
B. Both Assertion and Reason are correct statements , and Reason is not the correct explanation of the Assertion.
C. Assertion is correct, but Reason is wrong statement.
D. Assertion is wrong but Reason is correct statement.

Explanation

To solve the question regarding the assertion and reason about the hydrolysis of SF6 and SF4, we will analyze both statements step by step.

### Step 1: Analyze the Assertion
The assertion states that SF6 cannot be hydrolyzed, whereas SF4 can be hydrolyzed.

- **Understanding SF6**: Sulfur hexafluoride (SF6) is a molecule where a sulfur atom is surrounded by six fluorine atoms. The highly electronegative fluorine atoms create a strong bond with sulfur, making it stable and resistant to hydrolysis.
- **Conclusion from Assertion**: The assertion is correct; SF6 cannot be hydrolyzed due to the stability provided by the six fluorine atoms.
