Using the valence bond approach, predict the shape, hybridisation and magnetic behaviour of `[Ni(CO)_(4)]`. (at. no. of Ni = 28)

A

`dsp^(2)`, paramagnetic

B

`dsp^(2)`, diamagnetic

C

`sp^(3)`, paramagnetic

D

`sp^(3)`,diamagnetic

Text Solution

Verified by Experts

The correct Answer is:
D
`[Ni(CO)_(4)]`
`x+4(0)=0`
`x=0`
O, No. of Ni is zero
`Ni=[Ar]3d^(8)4s^(2)4p^(0)`

CO is a strong field ligand so 4s.
electron shift into 3d.

And no. of unpaired e-=0
So it has diamagnetic nature.
