# NEET Chemistry The p-Block Elements (XII) Questions Solved

Assertion : $Pb{I}_{4}$  is not known probably because of the oxidising power of Pb(IV) and reducing
power of ${I}^{-}$.

Reason :  Iodide stabilizes higher oxidation state.

(C) $P{b}^{2+}$  is more stable because of inert pair effect. ${I}^{-}$ being larger has the tendency to lose the electron easily.

Smaller and highly electronegative elements like ${F}^{-}$ can stabilize the higher oxidation state
not ${I}^{-}$.
