Answer» Correct Answer - A::D The formula for `CFSE` in octahedral field is `CFSE=-0.4xx("number of electrons in" t_(2g))` `+0.6Deltaxx` (number of electrons in `e_(g)`) `+Pxx`(number of extra pairings compared to normal filling of electrons) Where `Delta=` octahedral crystal field splitting and `P=` pairing energy (A). `K_(4)[Fe(CN)_(6)]` is `3d^(6)` strong field ligand `t_(2g)^(6)e_(g)^(0)` with two extra pairings (B). `[MnCl_(6)]^(4-)` is `3d^(5)` weak field ligand `t_(2g)^(3)e_(g)^(2)` with not extra pairing (C). `[Ni(H_(2)O)_(6)]SO_(4)` is `3d^(8)` weak field ligand `t_(2g)^(6)e_(g)^(2)` with no extra pairing |
