Assertion (A) :` Pb^(+4)` compounds are stronger oxidiising agents than ` Sn^(4+)` compounds .
Reason (R): The higher oxidation states for group `14` elements are more stable for the heavier members of the group due to inert pair effect .

A

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

B

If both assertion and reason are true but reason in not the correct explation of the assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
C
Due to inert-pair effects, the higher oxidation states for the group `14` elements are less stable for the heavier members of the group and have a tendency to reduce to lesser oxidation state (i.e. These are stronger oxidation agent).
