C

`[Ni(CO)_(4)] and [Ni(CN)_(4)]^(2-)` are diamagnetic and `[NiCl_(4)]^(2-)` is paramagnetic

D

`[Ni(CO)_(4)]` is diamagnetic and `[NiCl_(4)]^(2-) and [Ni(CN)_(4)]^(2-)` are paramagnetic .

Text Solution

Verified by Experts

The correct Answer is:
C
`[Ni(CO)_(4)] and [Ni(CN)_(4)]^(2-)` are both diamagnetic with no unpaired electrons `[NiCl_(4)]^(2-)` is paramagnetic with two unpaired electrons.
