Vedclass · Answer

(B) The element $Y$ forms two chlorides $YCl_n$ and $YCl_{n-2}$,which indicates that the element exhibits variable valency with a difference of $2$ in oxidation states. This is a characteristic property of the inert pair effect observed in $p$-block elements. Specifically,for group $14$ elements like $Sn$ (Tin),it forms $SnCl_4$ (a volatile liquid) and $SnCl_2$ (a solid). Thus,element $Y$ belongs to group $14$.

$A$ solid element $Y$ conducts electricity and forms two types of chlorides: $YCl_n$ (a colorless volatile liquid) and $YCl_{n-2}$ (a colorless solid). To which group does element $Y$ belong?
