Vedclass · Answer

(A) The $Mn$ atom in $KMnO_4$ has a $+7$ oxidation state with an electron configuration of $[Ar] 3d^0 4s^0$.Since there are no unpaired electrons present,$d-d$ transitions are not possible.The intense purple colour of $KMnO_4$ arises due to $L \rightarrow M$ (ligand to metal) charge transfer,specifically from the $2p$ orbitals of $O$ to the $3d$ orbitals of $Mn$.

The colour of $KMnO_4$ is due to
