Question

Which of the following species is not stable ? (A) [Sn(OH)6]2- (B) [SiCl6]2- (C) [SiF6]2- (D) [GeCl6]2-

bullet Due to presence of d-orbital in Si, Ge and Sn they form species like SiF62- , [GeCl6]2- , [Sn(OH)6]2- bullet SiCl62- does not exist because six large chloride ions cannot be accommodated around Si4+ due to limitation of its size.

Q. Which of the following species is not stable ?

$[S n (O H)_{6}]^{2 -}$

$[S i C l_{6}]^{2 -}$

$[S i F_{6}]^{2 -}$

$[G e C l_{6}]^{2 -}$

$∙$ Due to presence of d-orbital in Si, Ge and Sn they form species like $S i F_{6}^{2 -}, [G e C l_{6}]^{2 -}, [S n (O H)_{6}]^{2 -}$
$∙$ $S i C l_{6}^{2 -}$ does not exist because six large chloride ions cannot be accommodated around $S i^{4 +}$ due to limitation of its size.
