Which complex compound possesses `sp^(3)d^(2)` hybridization

A

`[Fe (NH_(3))_(6)]^(3+)`

B

`[Fe(CN)_(6)]^(4-)`

C

`[Fe(CN)_(6)]^(3-)`

D

`[Fe(Cl)_(6)]^(3-)`

Text Solution

Verified by Experts

The correct Answer is:
D
`Cl^(-)` being a weak field ligand , does not cause pairing of d -electrons in the metal atom and thus forms outer orbital complex.
in `[Fe(Cl)_(6)]^(3-),` Fe is present as `Fe^(3+)`
` Fe^(3+)`
