Text Solution

Verified by Experts

The correct Answer is:
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
