MCQ

Assertion : $PbI_4$ is a stable compound.

Reason : Iodide stabilizes higher oxidation state

A
If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
B
If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
C
If the Assertion is correct but Reason is incorrect.
✓
If both the Assertion and Reason are incorrect.

✓

Answer

Correct option: D.

If both the Assertion and Reason are incorrect.

d
As we move down the group $IVA$, $+2$ oxidation state becomes more stable. Thus $Pb^{4+}$ is not possible, i.e., $PbI_4$ is highly unstable. $I_2$ is a weak oxidising agent so it cannot oxidise $Pb$ to $Pb^{4+}$ oxidation state. So assertion and reason both are wrong.
