Vedclass · Answer

(C) $CCl_4$ does not undergo hydrolysis because $C$ lacks $d$-orbitals to accept electrons from water molecules,whereas $SiCl_4$ does undergo hydrolysis.Therefore,statement $(I)$ is incorrect.Group $14$ elements exhibit $(+4)$ and $(+2)$ oxidation states.Due to the inert pair effect,the stability of the $(+4)$ oxidation state decreases down the group,while the stability of the $(+2)$ oxidation state increases.Thus,$GeX_4$ is more stable than $GeX_2$,and $PbX_4$ is less stable than $PbX_2$.Therefore,statements $(II)$ and $(III)$ are correct.The stability of dihalides increases down the group,so statement $(IV)$ is incorrect.

The correct statements with respect to halides of group $14$ elements are:
$I$. Both $CCl_4$ and $SiCl_4$ undergo hydrolysis
$II$. $GeX_4$ is more stable than $GeX_2$
$III$. $PbX_4$ is less stable than $PbX_2$
$IV$. Stability of dihalides decreases down the group.
