The correct order of magnetic moments (spin values in B.M.) among is:

Options

A. `[Fe(CN)_(6)]^(4-) gt [MnCl_(4)]^(2-)gt [CoCl_(4)]^(2-)`
B. `[MnCl_(4)]^(2-) gt [Fe(CN)_(6)]^(4-)gt [CoCl_(4)]^(2-)`
C. `[MnCl_(4)]^(2-)gt [CoCl_(4)]^(2-) gt [Fe(CN)_(6)]^(4-)`
D. `[Fe(CN)_(6)]^(4-)gt[CoCl_(4)]^(2-)gt[MnCl_(4)]^(2-`

Answer

C

Explanation

Magnetic moment `=sqrt(n+2)`
Where, n = number of unpaired electron i.e., greater the number of unpaired electron greater will be the paramagnetic character.
