$KMnO_4$

Vedclass · Answer

(A) In $KMnO_4$,the oxidation state of $Mn$ is $+7$. The electronic configuration of $Mn^{7+}$ is $[Ar] 3d^0$. Although it has no unpaired electrons,it is intensely purple due to charge transfer spectra (ligand to metal charge transfer). In $K_2MnO_4$,$Mn$ is in $+6$ state $(3d^1)$,which has one unpaired electron. In $MnSO_4$,$Mn$ is in $+2$ state $(3d^5)$,which has five unpaired electrons. In $MnO$,$Mn$ is in $+2$ state $(3d^5)$,which has five unpaired electrons. Thus,$KMnO_4$ is colored despite having no unpaired electrons.

Which of the following compounds is colored but does not contain any unpaired electrons?
