Which of the electronic configuration according to crystal field theory of the compound is correct `[MnF_(6)]^(4-)` ? .

Options

A. `a. (t_(2g)^(5) e_(g)^(0))`
B. `b. (t_(2g)^3 e_(g)^(2))`
C. `c. (e_(g)^(1) t_(2g)^(4))`
D. `d. (t_(2g)^(1) e_(g)^(4))`

Answer

b

Explanation

Octahedral complex `CN =6`
Weak ligand`F^(Θ)`
`Mn =3d^(5) 4s^(2) Mn^(2) =3d^(5)`
`:.3(t_(2g)e_(g)^(2))` .
