In the following question, a statement of Assertion (i). followed by a statement of Reason (R) is given. Choose the correct option out of the following choices:

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

(i) Both Assertion and Reason are correct statements and Reason is the correct explanation of Assertion.
(ii) Both Assertion and Reason are correct statements but Reason is not the correct explanation of Assertion.
(iii) Assertion is correct but Beason is wrong.
(iv) Assertion is wrong but Reason is correct.
(v) Both Assertion and Reason are wrong.

The answer is the option (i). H_{2}O can’t react with SF_{6} because the fluorine atoms don’t allow H_{2}O to attack SF_{6}, and thus, is sterically protected.
