Dehydration Synthesis

Definition

noun, plural: dehydration syntheses

A chemical reaction that builds up molecules by losing water molecules.


Supplement

It is a type of condensation reaction in which monomers join together into polymers while losing water molecules. This process is carried out by losing (-OH) from one of the monomers and (H) from another monomer. The two unstable monomers join together, and the (-OH) and (H) combine forming water (H2O).

For example, A-OH + B-H → AB + HOH


Word origin: dehydrate: to lose or remove water + Latin, synthesis: composition
Compare: hydrolysis.
See also: condensation, monomer, polymer, water, chemical bond.
