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 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.


Condensation reaction: 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


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.


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.


A condensation reaction occurs when two molecules join to form a larger molecule and release a smaller molecule(s) in the process. The smaller molecule lost in the reaction is often water, but it can also be methanol, hydrogen chloride, acetic acid or several other molecules.Condensation reactions occur naturally in biological and chemical processes on Earth or synthetically by man-made means.


Condensation reactions are important for the creation of many important biological molecules, such as carbohydrates and proteins. Examples: 1. The reaction of two identical molecules: When two identical molecules combine to produce a condensation reaction, it is known as intramolecular condensation or self-condensation. 2.
