What Is Disproportionation Reaction?

Are you curious to know what is disproportionation reaction? You have come to the right place as I am going to tell you everything about disproportionation reaction in a very simple explanation. Without further discussion let’s begin to know what is disproportionation reaction?

Disproportionation reactions, a fascinating aspect of chemical transformations, play a significant role in the realm of chemistry. Whether you’re a student navigating Class 11 studies or an enthusiast seeking to delve into chemical reactions, this article aims to unravel the complexities of disproportionation reactions, providing insights, examples, and clarity.

What Is Disproportionation Reaction?

A disproportionation reaction is a type of redox reaction where a single substance undergoes both oxidation and reduction simultaneously, leading to the formation of two different oxidation states. This intriguing process involves the same element both gaining and losing electrons within the same chemical species.

What Is Disproportionation Reaction In Chemistry?

In the realm of chemistry, disproportionation reactions are fundamental to understanding the behavior of certain elements. These reactions are characterized by the simultaneous occurrence of oxidation and reduction within a single reactant, showcasing the versatility and dynamic nature of chemical transformations.

What Is Disproportionation Reaction With Example?

An excellent example to illustrate disproportionation is the reaction involving hydrogen peroxide (H2O2). In this case, hydrogen peroxide undergoes disproportionation to produce water (H2O) and oxygen (O2).

2H2O2 →2H2O+O2

This reaction showcases hydrogen peroxide transforming into water and oxygen, with oxygen simultaneously undergoing reduction and hydrogen peroxide undergoing oxidation.

What Is Disproportionation Reaction With Example Class 11:

For Class 11 students, understanding disproportionation reactions is a vital part of their chemistry curriculum. The example mentioned above serves as a practical illustration of disproportionation and offers valuable insights into the principles of redox reactions.

Disproportionation Reaction Examples Pdf:

To delve deeper into disproportionation reactions, consulting comprehensive examples in a PDF format can be beneficial. This resource can provide a collection of reactions involving various elements, aiding in a more extensive exploration of this intriguing chemical phenomenon.

Difference Between Redox And Disproportionation Reaction:

While disproportionation reactions fall under the broader category of redox reactions, it’s crucial to distinguish between the two. Redox reactions involve the transfer of electrons between two species, while disproportionation reactions specifically entail a single substance undergoing simultaneous oxidation and reduction.

Disproportionation Reaction Is Also Known As:

Disproportionation reactions are also known as autoxidation or autoreduction reactions. These alternative terms highlight the self-induced oxidation and reduction processes occurring within the same chemical species.

Comproportionation Reaction:

On the flip side, comproportionation reactions involve two reactants with different oxidation states combining to form a product with an intermediate oxidation state. The contrast between comproportionation and disproportionation reactions adds depth to the understanding of redox processes.

Example Of Disproportionation Reaction In Aqueous Solution:

Consider the reaction involving chlorine (Cl2) in an aqueous solution:

3Cl 2 +6OH − →5Cl − +ClO3− +3H2O

In this reaction, chlorine undergoes disproportionation to produce chloride ions (Cl −) and chlorate ions (ClO3−), showcasing both oxidation and reduction within the same element.


In conclusion, understanding disproportionation reactions is pivotal for anyone delving into the intricate world of chemistry, especially for Class 11 students. From the fundamental definition to practical examples and the distinction from other redox reactions, this guide aims to demystify the complexities surrounding disproportionation reactions. Whether you’re exploring examples in a PDF format or grasping the concept through aqueous solutions, the diverse facets of disproportionation reactions invite curiosity and further exploration in the fascinating realm of chemical transformations.


What Is A Disproportionation Reaction Class 11?

Disproportionation reaction, also called dismutation reaction, is basically a type of redox reaction involving simultaneous reduction and oxidation of atoms of the same element from one oxidation state (OS) to two different oxidation states.

What Is Redox And Disproportionation?

In redox reactions, one substance is oxidised and the other one is reduced. Eg:- 2Mg + O2 ==> 2MgO. On the other hand in disproportionation reactions, one substance is oxidised and that same substance gets reduced as well.

Is H2o A Disproportionation Reaction?

The decomposition reaction 2H₂O₂ → 2H₂O + O₂ is also a disproportionation reaction because O is reduced in forming H₂O and oxidized in forming O₂. Some disproportionation reactions are not decompositions, but they all involve the simultaneous oxidation and reduction of the same element.

What Is The Definition Of Displacement And Disproportionation Reaction?

In displacement reactions, one or more atoms is swapped out for another. … In combustion reactions, a compound reacts with oxygen to produce carbon dioxide, water, and heat. In disproportionation reactions, a molecule is both reduced and oxidized; these types of reactions are rare.
