A reaction in which oxidation numbers change.

Reason: Redox reactions involve transfer of electrons, which shows up as changes in oxidation states of elements. Double replacement and neutralization reactions typically do not change oxidation numbers (they're not usually redox), and a reaction with no electron transfer cannot be a redox reaction.
