undergoes disproportionation reaction in acidic medium but
does not. Give reason.
In , Mn has the highest oxidation state (+7); therefore, it cannot undergo oxidation which is required for disproportionation here. Hence
doesn’t undergo disproportionation reaction. Whereas in
manganese is in +6 (i.e., less than that of in
) oxidation state which can be oxidised as well as reduced, hence it undergoes disproportionation.
