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

Options

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

Answer

B

Explanation

For `Mn^(+2) to n=5" For " Co^(+2) to n=3`
For `Fe^(+2) to n=4`
