Assertion: The purple colour of KMnO4 is...

Assertion: The purple colour of `KMnO_4` is due to the charge transfer transition.
Reason: Manganese in `KMnO_4` has +7 oxidation state

Text Solution

Verified by Experts

Correct explanation.The intense colourof `KMnO_(4)` is not due to d-d transition but due to charge transfer from O to M ( Ligand to Metal) reducing the oxidation state of Mn from `+7` to `+6 ` temporarily.
