Question
Which of the following complex ions has electrons that are symmetrically filled in both t2g and eg orbitals ?
Options
A.[FeF3]3-
B.[Mn(CN)6]4-
C.[CoF6]3-
D.[Co(NH3)6]2+
Solution
(1) Fe3+ (d5) → t2g 3, eg2 (symmetrically filled)
(2) Mn2+(d5) → t2g 5,eg2 (t2g unsymmetrically filled)
(3) Co3+(d6) → t2g4, eg2 (non-unsymmetrical)
(4) Co2+(d7) → t2g6, eg2 (non-symmetrical)
(2) Mn2+(d5) → t2g 5,eg2 (t2g unsymmetrically filled)
(3) Co3+(d6) → t2g4, eg2 (non-unsymmetrical)
(4) Co2+(d7) → t2g6, eg2 (non-symmetrical)
