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 Overview: There are a few varieties of condensation reactions, and all require those two pieces. Sometimes metal-complex catalysts are added, but luckily most undergrad Orgo classes focus on base-catalyzed mechanisms! You'll likely see these reactions again later in carbohydrate chemistry or in Biology class.
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.

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.
An example is the Dieckmann condensation, in which the two ester groups of a single diester molecule react with each other to lose a small alcohol molecule and form a β-ketoester product. Many condensation reactions follow a nucleophilic acyl substitution or an aldol condensation reaction mechanism (see previous concept for more information).
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.
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 a chemical reaction between two compounds where one of the products is water, ethanol, acetic acid, hydrogen sulfide, or ammonia.A condensation reaction is also known as a dehydration reaction.This type of reaction forms an addition product and water in the presence of a catalyst or under acidic or basic conditions.
