Consider that a `d^(6)` metal ion `(M^(2+))` forms a complex with aqua ligands , and the spin only magnetic moment of the complex is 4.90 BM . The geometry and the crystal field stabilization energy of the complex is :

Options

A. `[V(H_(2)O)_(6)]^(3+)`
B. `[Cr(H_(2)O)_(6)]^(3+)`
C. `[Cu(CN)_(4)]^(2-)`
D. `[MnCl_(4)]^(2-)`

Answer

A

Explanation

`V^(3+)` in `[V(H_(2)O)_(6)]^(3+)`
`mu_(Exp)=sqrt(2(2+2))+2.83BM`
