Pick out the correct statement with respect to `[Mn(CN)_(6)]^(3-)`:

Options

A. It is `dsp^(2)` hybridised and square planar
B. It is `sp^(3)d^(2)` hybridised and octahedral
C. It is `sp^(3)d^(2)` hybridised and tetrahedral
D. It is `d^(2)sp^(3)` hybridised and octahedral

Answer

D

Explanation

`[Mn(CN)_(6)]^(3-)`
`x+6(-1)=-3`
`x-6=-3`
`x=-3+6impliesx=+3`

In presence of `CN^(-)` causes pairing

`therefore d^(2)sp^(3)` is required
Hence, it is octahedral in shape.
