$Sn^{+4} > Sn^{+2}$

Vedclass · Answer

(B) The inert pair effect is the tendency of the $ns^2$ electron pair to remain unionized due to the poor shielding of the intervening $d$ and $f$ orbitals,which increases as we move down a group.In group $14$,the stability of the $+4$ oxidation state decreases down the group,while the stability of the $+2$ oxidation state increases.For $Sn$ ($Group$ $14$),the $+4$ oxidation state is more stable than the $+2$ oxidation state because the inert pair effect is less pronounced in $Sn$ compared to $Pb$.Thus,$Sn^{+4} > Sn^{+2}$ is the correct order of stability.In contrast,$Pb^{+2} > Pb^{+4}$,$Bi^{+3} > Bi^{+5}$,and $PbCl_4 > PbBr_4$ (due to the oxidizing nature of $Pb^{+4}$ and the reducing nature of halides).

Select the $CORRECT$ order of stability.
