Question

What is disproportionation reaction and give one example of it ?​

Answer 1

Examples. Hydrogen peroxide converting into water and oxygen is a disproportionation reaction. Water dissociating into H3O+ and OH- is an example of a disproportionation reaction that is not a redox reaction.

Answer 2

A disproportionation reaction is when a multiatomic species whose pertinent element has a specific oxidation state gets oxidized and reduced in two separate half-reactions, yielding two other products containing the same pertinent element. A convenient example is Mn2O3 becoming Mn2+ and MnO2 .
