Give the electronic configuration of the following complexes on the basis of Crystal Field Splitting theory. [CoF_(6)]^(3-),[Fe(CN)_(6)]^(4-) and [Cu(NH_(3))_(6)]^(2+).

Answer»

Solution :`[CoF_(6)]^(3-)" has "Co^(3+)(d^(6))"viz".t_(2g)^(4)e_(g)^(2)`,
`[Fe(CN)_(6)]^(4-)" has "Fe^(2+)(d^(6))"viz. " t_(2g)^(6)e_(g)^(0)`,
`[Cu(NH_(3))_(4)]^(2+)" has "Cu^(2+)(d^(9))" viz. "t_(2g)^(6)e_(g)^(3)`.
