Équilibre(ou tautomérie) céto-énolique. Les énols sont les formes tautomères des aldéhydes et des cétones énolisables. Plus énolisables(«transformables en énol»), c'est-à-dire possédant un atome d’hydrogène sur le carbone en alpha de la fonction carbonyle. Ces composés carbonylés sont en équilibre avec leur forme tautomère, leur énol. On appelle cet équilibre l'équilibre céto-énolique. 2, record 2, French, - %20%C3%A9quilibre%20c%C3%A9to%2D%C3%A9nolique

... the existence of two or more chemical compounds that are capable of facile interconversion, in many cases merely exchanging a hydrogen atom between two other atoms, to either of which it forms a covalent bond. Unlike other classes of isomers, tautomeric compounds exist in mobile equilibrium with each other, so that attempts to prepare the separate substances usually result in the formation of a mixture that shows all the chemical and physical properties to be expected on the basis of the structures of the components. 2, record 4, English, - tautomerism
