B

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

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-)` do not contain any unpaired electron while `[NiCl_(4)]^(2-)` contains two unpaired electrons.
