Question

Define Disproportionation..

Lo Points Lo.Aur Lo.
Mera Pas Khoob Points Hain...xD xD​

Answer 1

$\huge\underline\mathrm\pink{Answer}$

In chemistry, disproportionation, sometimes called dismutation, is a redox reaction in which one compound of intermediate oxidation state converts to two compounds, one of higher and one of lower oxidation states.

Answer 2

$\red { \underline{ \boxed{ \sf { \bigstar \: Answer}}}}$

The definition of Disproportionation in chemistry is that one substance simultaneously gets oxidised as well as reduced.

Example:

2 H₃PO₂ -----------> H₃PO₄ + PH₃

In the above reaction, the oxidation state of Phosphorus in H₃PO₂ ( Hypo Phosphorus acid) is +1.

It gets oxidised by converting into H₃PO₄ (Phosphoric acid), where the oxidation state of 'P' is +5.

It gets reduced by converting into PH₃ (Phosphine), where the oxidation state of 'P' is -3.
