or Aryl group]] Esters are a class of ''), an old name for ethyl acetate. Esters can be Synthesized in a Condensation Reaction between an acid an an Alcohol in a reaction known as Esterification . NOMENCLATURE An ester is named according to the two parts that make it up: the part from the alcohol and the part from the acid (in that order), for example ethyl sulfuric acid ester. Since most esters are derived from carboxylic acids, a specific nomenclature is used for them. For esters derived from the simplest carboxylic acids, the traditional name for the acid constituent is generally retained, e.g. formate, acetate, propionate, butyrate. IUPAC parent groups using traditional names For esters from more complex carboxylic acids, the systematic name for the acid is used, followed by the suffix ''-oate''. For example, Methyl Formate is the ester of methanol and methanoic acid (formic acid): the simplest ester. It could also be called ''methyl methanoate''. IUPAC naming of esters Esters of Aromatic acids are also encountered, including Benzoate s such as Methyl Benzoate , and Phthalates , with substitution allowed in the name. PHYSICAL PROPERTIES Esters participate in , Gas Liquid Chromatography , or Mass Spectrometry . Many esters have distinctive odors, which has led to their use as artificial flavorings and fragrances. For example: ESTER SYNTHESIS "Esterification" (condensation of an alcohol and an acid) is not the only way to synthesize an ester. Esters can be prepared in the laboratory in a number of other ways:
