Question

Which of the following complex species does not involve inner orbital hybridisation? (A) [ CoF 6]3- (B) [ Co ( NH 3)6]3+ (C) [ Fe ( CN)6]3- (D) [ Cr ( NH 3)6]3+

[CoF6]3- is a outer orbital complex ion. It involves outer orbital hybridisation. It has sp3d2- hybridisation because F- is a weak ligand.

Q. Which of the following complex species does not involve inner orbital hybridisation?

$[C o F_{6}]^{3 -}$

$[C o (N H_{3})_{6}]^{3 +}$

$[F e (CN)_{6}]^{3 -}$

$[C r (N H_{3})_{6}]^{3 +}$

$[C o F_{6}]^{3 -}$ is a outer orbital complex ion. It involves outer orbital hybridisation. It has $s p^{3} d^{2} -$ hybridisation because $F^{-}$ is a weak ligand.
