Definition of Condensation Reaction

Condensation Reaction Definition: A condensation reaction is a chemical reaction between two compounds where one of the products is water or ammonia.

Also Known As: Dehydration reaction

Examples: Reactions that produce acid anhydrides are condensation reactions. For example: acetic acid (CH3COOH) forms acetic anhydride ((CH3CO)2O) and water by the condensation reaction

2 CH3COOH → (CH3CO)2O + H2O

Condensation reactions are also involved in the production of many polymers.
