	Enol - Wikipedia, the free encyclopedia
		Enol (or, more officially, but less commonly: alkenol) is an alkene with hydroxyl group on one of the carbon atoms of the double bond.
		Enols and carbonyl compounds (such as ketones and aldehydes) are in fact isomers; this is called keto-enol tautomerism:
		The enol form is shown on the left.

	Enol Summary
		Enols are the tautomeric isomers of certain ketones Enolates are the conjugate bases of enols and are important intermediates in both synthetic and biosynthetic chemistry, where the act as nucleophiles in many different substitution reactions..
		The words enol and alkenol are combinations of the words alkene (or just -ene, the suffix given to alkenes) and alcohol (which represents the enol's hydroxyl group).
		The resonance from the enol is exactly analogous to that used to explain the acidity of phenols and consists of the delocalisation of the negative charge of the enolate ion to the alpha-carbon.

	Keto-enol tautomerism - Wikipedia, the free encyclopedia
		In certain aromatic compounds such as phenols the enol is important due to the aromatic character of the enol but not the keto form.
		When the enol form is complexed with chromium tricarbonyl, complete conversion to the keto form accelerated and occurs even at room temperature in benzene.
		Hydration of alkynes (of the general form RC≡CR, where R is an alkyl group or hydrogen), produces an enol that is in equilibrium with the keto form.
