Ester bonds are formed by the reaction of a carboxylic acid and an alcohol, with the elimination of a water molecule. They are characterized by a carbonyl group (C=O) linked to an oxygen atom (O) that is further bonded to an alkyl or aryl group. Esters are commonly found in fragrances, flavorings, and as solvents.
