MnO_{4}^{2-}undergoes disproportionation reaction in acidic medium but MnO_{4}^{-} does not. Give reason.

Answers (1)

In MnO_{4}^{-}, Mn has the highest oxidation state (+7); therefore, it cannot undergo oxidation which is required for disproportionation here. Hence MnO_{4}^{-} doesn’t undergo disproportionation reaction. Whereas in MnO_{4}^{2-} manganese is in +6 (i.e., less than that of in MnO_{4}^{-}) oxidation state which can be oxidised as well as reduced, hence it undergoes disproportionation.
