Explanation:
•DEFINITION »
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.[1][2] More generally, the term can be applied to any desymmetrizing reaction of the following type: 2 A → A' + A", regardless of whether it is a redox or some other type of process.[3]
•EXAMPLES »
Mercury(I) chloride disproportionates upon UV-irradiation:
Hg2Cl2 → Hg + HgCl2
Phosphorous acid disproportionates upon heating to give phosphoric acid and phosphine:
4 H
3PO
3 → 3 H3PO4 + PH3
As mentioned above, desymmetrizing reactions are sometimes referred to as disproportionation, as illustrated by the thermal degradation of bicarbonate:
2 HCO−
3 → CO2−
3 + H2CO3
The oxidation numbers remain constant in this acid-base reaction. This process is also called autoionization.
Another variant on disproportionation is radical disproportionation, in which two radicals form an alkane and alkene.
