$Pb^{2+}$

Vedclass · Answer

(A) The correct option is $A$.In group $14$ elements,as we move down the group,the stability of the $+2$ oxidation state increases due to the inert pair effect.The inert pair effect is the reluctance of the $ns^2$ electron pair to participate in bonding.Therefore,the stability order for the $+2$ oxidation state is $Si^{2+} Thus,$Pb^{2+}$ is the most stable.
