In a disproportionation reaction, the same element is simultaneously oxidized and reduced.
Definition
The reactions in which single reactant is oxidized and reduced is known as Disproporionation reactions
The disproportionation reaction is given below
2H₂O₂ → 2H₂O + O₂
is also a disproportionation reaction because O is reduced in forming H₂O and oxidized in forming O₂
Examples
Listed below are the examples of disproportionation reaction
- P4 + 3NaOH + 3H2O → 3NaH2PO2 + PH3
- Cl2(g) + H2O (l) →HCl (aq)+ HClO(aq)
- 2CuBr⟶CuBr2+Cu
