Vedclass · Answer

(B) $Ge$ is an element of group $14$ (carbon family). In group $14$,both $+2$ and $+4$ oxidation states are possible. For $Ge$,the $+4$ oxidation state is more stable than the $+2$ oxidation state. Due to the inert pair effect,which arises from the poor shielding of $s$-electrons by intervening $d$ and $f$-electrons,the stability of the $+4$ oxidation state decreases down the group from $Ge$ to $Pb$. Consequently,for $Pb$,the $+2$ oxidation state is more stable than the $+4$ oxidation state. Therefore,the statement "$GeX_2$ is more stable than $GeX_4$" is incorrect.

Which of the following is not correct corresponding to the chemistry of group $14$ elements?
