The magnetic moment (spin only) of `[NiCl_(4)]^(2-)` is :

A

2.82 BM

B

1.41 BM

C

1.82 BM

D

5.46 BM

Text Solution

Verified by Experts

The correct Answer is:
A
In `[NiCl_(4)]^(2-), Ni^(2+): 3d^(8)4s^(@)`

No. of unpaired electrons = 2
Magnetic moment, `u=sqrt(n(n+2))`
`=sqrt(2(2+2))=2sqrt(2)=2xx1.414=2.828BM`
