WebKeto Enol Tautomerism. Keto Enol Tautomerism is a process where an equilibrium occurs between the keto form (ie a normal-looking ketone) and the enol form (a double bond adjacent to an alcohol) of a carbonyl, acheived through the movement of atoms and breaking of single bonds. Spoiler alert: In most cases, the keto form is highly favored.
