Vedclass · Answer

(D) In group $14$ (or $IVA$),the stability of the $+2$ oxidation state increases down the group due to the inert pair effect. $Pb$ is at the bottom of the group,so $Pb^{2+}$ is much more stable than $Pb^{4+}$. $I^-$ is a mild reducing agent and cannot oxidize $Pb^{2+}$ to $Pb^{4+}$. Therefore,$PbI_4$ is not a stable compound. Both the Assertion and the Reason are incorrect.

Assertion : $PbI_4$ is a stable compound.
Reason : Iodide stabilizes higher oxidation state.
