The hybridization states of `[Ni(CO)_(4)], [Ni(CN)_(4)]^(2-)` and `[NiCl_(4)]^(2-)` species are respectively

Options

A. `sp^(3), sp^(3), dsp^(2)`
B. `dsp^(2), sp^(3), sp^(3)`
C. `sp^(3), dsp^(2), dsp^(2)`
D. `sp^(3), dsp^(2), sp^(3)`

Answer

D

Explanation

`[Ni(CO)_(4)]` is tetrahedral : `sp^(3)` hybridisation
`[Ni(CN)_(4)]` is square planar : `dsp^(2)` hybridisation
`[NiCl_(4)]^(2-)` is tetrahedral : `sp^(3)` hybridisation
