`MnO_(4)^(-)` is of intense pink colour, though `Mn` is in`(+7)` oxidation state.It is due to:

A

oxygen gives colour to it

B

charge transfer when Mn gives its electron to oxygen

C

charge transfer when oxygen gives its electron to Mn making it `Mn(+VI)` hence coloured

D

None is correct.

Text Solution

Verified by Experts

The correct Answer is:
C

Mn is in `+7` o.s. having no unpaired `e^(-)` Pink coloure of `MnO_(4)^(-)` is due to charge transfer.

Transition metals usually from coloured complexes and d-d transitions (t_(2g)hArre_(g)) are responsible for colour as the energy difference between t_(2g) and e_(g) lies in visible region. But all the coloured ions are not dut to d-d transition but charge transfer bands also play important roles. Charge transfer bands may be of two types. (i) ligand to metal (CTLM) " "(ii) metal to ligand (CTML). Charge transfer transition always produces intense colour as compared to d-d transition.
