For the tetrahedral complex `[MnBr_(4)]^(2-)` the spin only magnetic moment value is…. (Atomic No. Of Mn=25)

A

1.7

B

5.9

C

4.8

D

2.4

Text Solution

Verified by Experts

The correct Answer is:
B
Oxidation number is `+2(Mn^(+2))` in `[MnBr_(4)]^(2-)`
`:. 5` unpaired electrons in `Mn^(+2)`
`:. mu= sqrt(5(5+2))BM = 5.9`
