The geometry and magnetic behaviour of t...

The geometry and magnetic behaviour of the complex `[Ni(CO)_4]` are

A

square planar geometry and paramagnetic

B

Tetrahedral geometry and diamagnetical

C

Square planar geometry and diamagnetic

D

Tetrahedral geometry and paramagnetic

Text Solution

Verified by Experts

The correct Answer is:
B
`Ni(28):[Ar]3d^(8)4s^(2)`
`because` CO is a strong field ligand
Configuaration would be

For, four 'CO'-ligands hybridisation would be `sp^(3)` and thus the complex would be diamagnetic and of tetrahedral geometry .
