Q. Which of the following complex species does not involve inner orbital hybridisation?
A) $\left\lbrack {CoF}_{6} \right\rbrack^{3 -}$
B) $\left\lbrack Co\left( {NH}_{3} \right)_{6} \right\rbrack^{3 +}$
C) $\left\lbrack Fe(CN)_{6} \right\rbrack^{3 -}$
D) $\left\lbrack Cr\left( {NH}_{3} \right)_{6} \right\rbrack^{3 +}$
Explanation
(a)
$\left\lbrack CoF_{6} \right\rbrack^{3 -}$is an outer orbital complex ion. It involves outer orbital hybridisation. It has $sp^{3}d^{2}$-hybridisation because $F^{-}$ is a weak ligand.
