Compound produced by dehydration of a carbonic acid. General formula is R--C--O--C--R. Chemical compound that reacts with water to form an acid and are usually oxides of nonmetallic elements.

Anhydrides are generally more reactive than their corresponding acids because they are able to react with water to form their corresponding acid.
