WebAlthough the reaction of carbonyl compounds with sodium hydride is heterogeneous and slow, sodium enolates are formed with the loss of hydrogen, and no other organic compounds are produced. Examples If the formed enolate is stabilized by more than one carbonyl it is possible to use a weaker base such as sodium ethoxide. Web(iii) OH + H 2 O * H 2 O + *OH The OH – will deprotonate the 18 O – enriched water to form the *OH –. *OH – then attacks the methanal via nucleophilic addition reaction. (iv) The carbonyl carbon in aldehyde is less sterically hindered than that in ketones, hence more easily attacked by the nucleophile.
WebDec 26, 2015 · When a carbonyl compound and water are present together, an equilibrium is set up between the carbonyl compound and the corresponding gem-diol.

WebShort-chain carbonyl compounds are soluble in water. This is because the carboxyl group contains an oxygen atom with lone pairs of electrons. These lone pairs of electrons can … WebSince the carbonyl group of the carbonyl form is strongly electrophilic and reacts with a variety of nucleophiles, it would be reasonable to expect the strongly nucleophilic enolate …
WebJul 31, 2024 · 17.2: Enolization of Aldehydes and Ketones. Transformation of a carbonyl compound to an enol at a useful rate normally requires either a basic catalyst or an acidic catalyst and, of course, at least one hydrogen on the α carbon. The features of each type of catalysis follow. Enolization in Basic Solution.
