Aldol
Encyclopedia
An aldol or aldol adduct (from "Aldehyde alcohol") is a beta-hydroxy
ketone
or aldehyde
, and is the product of aldol addition
(as opposed to aldol condensation
, which produces an α,β-unsaturated carbonyl moiety).
Typically, "aldol" refers to 3-hydroxybutanal
.

Ketone
In organic chemistry, a ketone is an organic compound with the structure RCR', where R and R' can be a variety of atoms and groups of atoms. It features a carbonyl group bonded to two other carbon atoms. Many ketones are known and many are of great importance in industry and in biology...

Aldol reaction
The aldol reaction is a powerful means of forming carbon–carbon bonds in organic chemistry.Discovered independently by Charles-Adolphe Wurtz and Alexander Porfyrevich Borodin in 1872, the reaction combines two carbonyl compounds to form a new β-hydroxy carbonyl compound...

Aldol condensation
An aldol condensation is an organic reaction in which an enol or an enolate ion reacts with a carbonyl compound to form a β-hydroxyaldehyde or β-hydroxyketone, followed by a dehydration to give a conjugated enone....
