Question

Assertion: PbI4 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 (D) If both the Assertion and Reason are incorrect

Due to screening effect, down the group, lower oxidation states become more stable. e.g., Pb(II) is more stable than Pb(IV). But small, highly electronegative elements like F atoms can somewhat stabilise its higher oxidation state.

Q. Assertion : $P b I_{4}$ is a stable compound.
Reason : Iodide stabilizes higher oxidation state

If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.

If the Assertion is correct but Reason is incorrect

If both the Assertion and Reason are incorrect

If the Assertion is incorrect but the Reason is correct.

Due to screening effect, down the group, lower oxidation states become more stable. e.g., $P b (II)$ is more stable than $P b (I V)$ . But small, highly electronegative elements like $F$ atoms can somewhat stabilise its higher oxidation state.
