High spin complex `[FeCI_(6)]^(3-)` has th d-configuration

A

`t_(2g)^(3)" " theta_(g)^(2)`

B

`t_(2g)^(5)`

C

`t_(2g)^(2)" " theta_(g)^(3)`

D

`e_(g)^(5)`

Text Solution

Verified by Experts

(a) In `[FeCI_(6)]^(3-)` complex , `CI^(-)` is weak field ligand It do not cause pairing of electron in 3 d subshell of `Fe^(3+)` Hence, configuration is `t_(2g)^(3) e_(g)^(2)`
