Web28 apr. 2024 · This is an important feature of ketone and aldehydes, and is known as the keto-enolic tautomery or keto-enol tautomerism, i.e. the equilibrium of carbonyl compounds between two forms. It must be stressed that the keto and the enol forms are two distinct compounds, not isomers. They are known as tautomers of each other. Webthe hydration of a terminal alkyne—Section 9.4.
