Charge transfer

Vedclass · Answer

(A) In $KMnO_4$,the manganese atom is in the $+7$ oxidation state,which corresponds to a $d^0$ electronic configuration. Since there are no $d$-electrons available for $d-d$ transition,the color cannot be attributed to $d-d$ transitions. The intense purple color of $KMnO_4$ arises due to the charge transfer from the oxygen ligand to the metal center $(O^{2-} \rightarrow Mn^{7+})$. This is known as ligand-to-metal charge transfer $(LMCT)$.

The purple color of $KMnO_4$ is due to which of the following?
