The keto and enol forms of propanal have to be drawn. Concept Introduction: Keto-Enol Tautomers: Aldehydes and ketones many exist is an equilibrium mixture of two constitutional or structural isomers called tautomers. Tautomers differ from one another in placement of a hydrogen atom and a double bond. One tautomer is the keto form. The keto form has the structural typical of an aldehyde or ketone. The other form is called the enol form. The enol form has a structure containing a carbon-carbon double bond (en) and a hydroxyl group, the functional group of alcohols (ol). The keto form of aldehydes and ketones is most stable.
