What is a disproportionation reaction? Give one example.
Original Khojo Papers practice question — not from a past board paper.
Answer
A disproportionation reaction is one in which the same element is simultaneously oxidised and reduced. When chlorine reacts with cold dilute alkali it gives chloride and hypochlorite, the oxidation number changing from 0 to −1 and to +1 at the same time.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The element must have an intermediate oxidation state for this to be possible.
