What is Cannizzaro’s Reaction?
The Cannizzaro reaction is a chemical transformation in redox chemistry that involves the base-induced disproportionation of two molecules of a non-enolizable aldehyde to yield a carboxylic acid and a primary alcohol. In other words, one molecule of the aldehyde undergoes oxidation to form the corresponding carboxylic acid, while the other molecule undergoes reduction to form the corresponding primary alcohol.
