Esters have a very sweet fruity smell. Naturally occurring esters are found in fruits. An ester is a product of the reaction of an acid (usually organic) and an alcohol (the hydrogen of the acid R-COOH is replaced by an alkyl group R').Esters mainly result from the condensation (a reaction that produces water) of a carboxylic acid and an alcohol.The process is called esterification.ommon names of esters are derived from the organic acid and the alcohol from which they are derived. For example, when acetic acid reacts with ethyl alcohol, the ester formed is called ethyl acetate. The IUPAC name is different.
