Question

What does disproportionation reaction mean?

Answer 1

A reaction in which species undergo simultaneous oxidation and reduction.

Here is an example of a disproportionation reaction:

`3BrF → BrF_3 + Br_2`

Univalent bromine (in the interhalogen `BrF`) is reduced to elemental bromine, and oxidized to `Br^(III+)`.
