Vedclass · Answer

(A) The inert pair effect refers to the reluctance of the $ns^2$ electron pair to participate in bonding due to poor shielding by $d$ and $f$ orbitals.For lead $(Pb)$,which belongs to group $14$,the $+2$ oxidation state becomes more stable than the $+4$ oxidation state as we move down the group.Therefore,lead forms compounds in the $+2$ oxidation state due to the inert pair effect.
