Vedclass · Answer

(B) $[SiF_6]^{2-}$ is formed but $[SiCl_6]^{2-}$ is not because the size of the $Cl^-$ ion is significantly larger than that of the $F^-$ ion.Due to the larger size of $Cl^-$,there is significant steric hindrance around the central $Si$ atom,which prevents the formation of the $[SiCl_6]^{2-}$ complex.While the electronegativity of $F$ is indeed higher than that of $Cl$,this property is not the primary reason for the stability of $[SiF_6]^{2-}$ over $[SiCl_6]^{2-}$.Therefore,both $(A)$ and $(R)$ are correct statements,but $(R)$ is not the correct explanation for $(A)$.

Assertion $(A): [SiF_6]^{2-}$ is formed but $[SiCl_6]^{2-}$ is not.
Reason $(R):$ Electronegativity $(EN)$ of $F$ is higher than $EN$ of $Cl$.
