Question
The color of KMnO4 is due to :
Options
A.L → M charge transfer transition
B.σ − σ* transition
C.M → L charge transfer transition
D.d − d transition
Solution
KMnO4 = Dark Purple (Mn+7 = 3d0 configuration)
*Purple coloration is due to Ligand to metal charge transfer spectra.
* During charge transfer oxidation state of Mn is temporary reduced to Mn+6
