Among `[Ni (CO)_4], [Ni(CN)_4]^(2-), [NiCl_4]^(2-)` species, the hybridisation states at the Ni atom are, respectively (Atomic number.of Ni=28)

Options

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

Answer

B

Explanation

`[NiCl_4]^(2-) to sp^3` hybridisation `to `tetrahedral `[Ni(CO)_4] to sp^3` hydridisation `to` tetrahedral
`[Ni(CN)_4]^(2-) to dsp^2` hybridisation `to` square planar
