$[SiCl_6]^{2-}$

Vedclass · Answer

(B) $[SiCl_6]^{2-}$ does not exist. The chlorine atom is significantly larger than the fluorine atom. Due to the large size of $Cl$ atoms,there is significant interelectronic repulsion when six $Cl$ atoms attempt to surround the central $Si$ atom. Consequently,the steric hindrance prevents the formation of the $[SiCl_6]^{2-}$ ion,making it unstable.
