Mechanism; Condensation Types; An aldol condensation is a condensation reaction in organic chemistry in which an enol or an enolate ion reacts with a carbonyl compound to form a β-hydroxyaldehyde or β-hydroxyketone, followed by dehydration to give a conjugated enone.. Aldol condensations are important in organic synthesis, because they provide a good way to form carbon–carbon bonds.


A condensation reaction is an organic reaction in which two smaller molecules combine to form a larger molecule and a much simpler molecule. The simpler molecule produced is often water, which is why the phrase "condensation reaction" is used, while sometimes being referred to as a dehydration.


A condensation reaction is a class of organic addition reaction that typically proceeds in a step-wise fashion to produce the addition product, usually in equilibrium, and a water molecule (hence named condensation).The reaction may otherwise involve the functional groups of the molecule, and formation of a small molecule such as ammonia, ethanol, or acetic acid instead of water.


Condensation reaction, any of a class of reactions in which two molecules combine, usually in the presence of a catalyst, with elimination of water or some other simple molecule.The combination of two identical molecules is known as self-condensation. Aldehydes, ketones, esters, alkynes (acetylenes), and amines are among several organic compounds that combine with each other and, except for ...


Condensation reaction: A reaction in which two or more molecules combine to form a larger molecule, with the simultaneous loss of a small molecule such as water or methanol. While this occurs in many reactions, the term is usually reserved for reactions in which a new carbon-carbon bond is formed.


Condensation Reactions. A condensation reaction is a reaction in which two molecules combine to form a single molecule.A small molecule, often water, is usually removed during a condensation reaction. Amino acids are important biological molecules that have an amine functional group on one end of the molecule and a carboxylic acid functional group on the other end.


There are said to be many types of reactions coming from this area such as elimination reactions, substitution, addition, condensation, reduction, dehydration, oxidation and hydrolysis reactions. Organic chemistry reactions are reactions that occur between organic compounds.


Aldol Condensation. In some cases, the adducts obtained from the Aldol Addition can easily be converted (in situ) to α,β-unsaturated carbonyl compounds, either thermally or under acidic or basic catalysis.The formation of the conjugated system is the driving force for this spontaneous dehydration.
