Vedclass · Answer

(C) $SiF_6^{2-}$ is known because $F$ has a small size,which allows six $F$ atoms to fit around the $Si$ atom without significant steric hindrance.In $SiCl_6^{2-}$,the $Cl$ atoms are much larger than $F$ atoms,leading to significant inter-electronic repulsions and steric hindrance,which makes the ion unstable.The reason provided is incorrect because the stability of $SiF_6^{2-}$ is primarily due to the small size of $F$ minimizing steric hindrance,not due to lone pair interaction with $d-$orbitals.

Assertion : $SiF_6^{2-}$ is known but $SiCl_6^{2-}$ is not.
Reason : Size of fluorine is small and its lone pair of electrons interacts with $d-$orbitals of $Si$ strongly.
