Atomic number of Mn, Fe, Co and Ni are 25, 26, 27 and 28 respectively. Which of the following outer orbital octahedral complexes have same number of unpaired electrons ?

Answer»

`[MnCl_(6)]^(3-)`
`[FeF_(6)]^(3-)`
`[CoF_(6)]^(3-)`
`[Ni(NH_(3))_(6)]^(2+)`

Solution :(a) and (C ) are `d^(4),d^(6)` respectively (HIGH spin)
