Wikipedia

Esters are chemical compounds derived by reacting an oxoacid (one containing an oxo group, X=O) with a hydroxyl compound such as an alcohol or phenol. Esters are usually derived from an inorganic acid or organic acid in which at least one -OH (hydroxyl) group is replaced by an -O-alkyl group, and most commonly from carboxylic acids and alcohols. Basically, esters are formed by condensing an acid with an alcohol.
