The complex having the highest spin-only magnetic moment is

Options

A. `[Fe(CN)_(6)]^(3-)`
B. `[Fe(H_(2)O)_(6)]^(2+)`
C. `[MnF_(6)]^(4-)`
D. `[NiCl_(4)]^(2-)`

Answer

C

Explanation

`{:((A)[Fe(CN)_(6)]^(3-),d^(5),"Low spin",n=1,mu=sqrt(2)),((B)[Fe(H_(2)O)_(6)]^(2+),d^(6),"High spin",n=4,mu=sqrt(4)),((C)[MnF_(6)]^(4-),d^(5),"High spin",n=5,mu=sqrt(35)),((D)[NiCl_(4)]_("Tetrahedral")^(2-),d^(8),"High spin",n=2,mu=sqrt(6)):}`
