Which one of the following ions exhibits d-d transition and paramagnetism as well?

Answer»

`MnO_(4)^(2-)`
`CrO_(4)^(2-)`
`MnO_(4)^(2-)`
`Cr_(2)O_(7)^(2-)`

Solution :`MnO_(4)^(2-)` (MANGANATE) ion has `Mn^(6+)`. Electron configuration of the `Mn^(6+)` is-

There is incomplete 3d in it. It has ONE electron in 3d, hence it is aromatici and hence d-d transition OCCURS in it.
