Acid Hydrolysis of Esters. Book chapter: 14. Pages: 472-511. Carbon atom of a carbonyl group is attached to a hydroxyl group forming a carboxyl group. As functional group – attached to an alkyl group or an aromatic group. IUPAC names. butanoate. provide the odor and flavor of many fruits, such as pineapples.. Learning Goal . . Write the IUPAC and common names for esters; draw condensed and line-angle structural formulas.. Naming Esters. States of matter.
