Question

Assertion :$Pb{l}_4$ is not known probably because of the oxidising power of Pb(IV) and reducing power of $I^{-}$. Reason: Iodide stabilizes higher oxidation state.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Assertion is incorrect but Reason is correct

Answer 1

The correct option is C Assertion is correct but Reason is incorrect

$S_1:P{b}^{2+}$ is more stable because of inert effect. $I^{-}$ being larger has the tendency to lose the electron easily.
$S_2$: Smaller and highly electronegative elements like $F^{-}$ can stabilize the higher oxidation state not $I^{-}$.
