The spin only magnetic moment of `Mn^(4+)` ion is nearly

A

3BM

B

6BM

C

4BM

D

5BM

Text Solution

Verified by Experts

The correct Answer is:
C
The electronic configuration of `Mn^(4+) is [Ar]3d^(3)`
thus, three unpaired electrons are present.
:.Spin only magnetic moment, `mu=sqrt(n(n+2))BM`
`:. mu=sqrt(15)=3.87~~4MB`
