High spin complex `[FeCI_(6)]^(3-)` has th d-configurationA. `t_(2g)^(3)" " theta_(g)^(2)`B. `t_(2g)^(5)`C. `t_(2g)^(2)" " theta_(g)^(3)`D. `e_(g)^(5)` |
Answer» (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)` | |
