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.
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 Definition. Condensation has multiple meanings in the field of biology. A condensation reaction is when two smaller molecules join to form a larger one by removing functional groups that form a small molecule, often water.Condensation can also refer to a state change in water from gas to liquid, which is an important step in the water cycle.
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 is a physical change in the state of matter of a substance. This change of state involves matter changing from a gas form to a liquid form because energy in the molecules involved was released. In other words, the substance is in the gas form because the molecules have a high amount of ...
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
Examples of Condensation Reactions Glycosylation. The basic glycosylation reaction happens when a molecule with a glycosyl group, like a carbohydrate, attaches to a functional group on another molecule. One of the most important and prevalent forms of glycosylation in nature is called N-linked glycosylation which is a post-translational process ...
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.
The following examples of condensation polymers are illustrative. Note that for commercial synthesis the carboxylic acid components may actually be employed in the form of derivatives such as simple esters. Also, the polymerization reactions for Nylon 6 and Spandex do not proceed by elimination of water or other small molecules.
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.
