    Nomenclature of Anhydrides - Chemistry LibreTexts

    Symmetrical anhydrides; Unsymmetrical acid anhydrides; Common names that you should know; Contributors; The acid anhydride functional group results when two carboxylic acids combine and lose water (anhydride = without water). Symmetrical acid anhydrides are named like carboxylic acids except the ending -acid is replaced with -anhydride. This is true for both the IUPAC and Common nomenclature.
