Assertion : Dinegative anion of oxygen ...

Assertion : Dinegative anion of oxygen ` (O^(2-))` is quite common but dinegative anion of sulphur `(S^(2-))` is less common.
Reason : Covalency of oxygen is two.

A

If both the assertion and reason are true and reason is correct explanation of the assertion .

B

If both the assertion and reason are true but reason is not a correct explanation of the assertion .

C

If the assertion is true but the reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
B
Oxygen is second most electronegative element after fluorine . So it can easily gain electrons to form dinegative anion ` (O^(2-))` while sulphur is not so electronegative element as oxygen.
