$MnO_4^{2-}$

Vedclass · Answer

(A) $LMCT$ (Ligand to Metal Charge Transfer) causes intense color in oxoanions of transition metals. $MnO_4^{2-}$ (manganate ion) has $Mn$ in the $+6$ oxidation state, which corresponds to a $3d^1$ electronic configuration. Since it has one unpaired electron, it is paramagnetic. Additionally, it exhibits color due to $LMCT$ from $O^{2-}$ to $Mn^{+6}$. In contrast, $MnO_4^{-}$, $Cr_2O_7^{2-}$, and $CrO_4^{2-}$ have $Mn^{+7}$ $(3d^0)$ and $Cr^{+6}$ $(3d^0)$ respectively, which are diamagnetic.

Which of the following species exhibits both $LMCT$ and paramagnetism?
