According to crystal field theory the electronic configuration of the `[FeCl_(4)]^(-)` ion is .

Options

A. `(t_(2g)^(2)e_(g)^(2))`
B. `(e_(g)^(2) t_(2g)^(3))`
C. `(e_(g)^(1) t_(2g)^(3))`
D. `(e_(g)^(3)t_(2g)^(1))`

Answer

B

Explanation

Tetrahedral complex `CN =4`
Weak ligand `CI^(Θ) ("No pairing High spin complex")`
`Fe = 3d^(6) 4s^(2), Fe^(+3) = 3d^(5)` :. Structure `=3(e^(2) t_(2)^(3))` .
