<h3>What is a dehydration synthesis reaction?</h3>
A dehydration reaction in chemistry is a chemical process in which the reacting molecule or ion loses water. The opposite of a hydration reaction, dehydration reactions are frequent processes.
Dehydration synthesis is a chemical reaction that joins two smaller molecules by eliminating atoms from each of them. Organic compounds can be further divided into aliphatic and aromatic compounds based on the structure of hydrocarbons. The generation of new compounds with changes in atom bonding can occur in a variety of chemical processes involving organic molecules.
