Ester is the condensation product of an Carboxylic acid and alcohol in organic chemistry.In condensation two molecules combine such that the eleimination of small molecule like water takes place. Or it could be said that ester are dehydration product of alcohol and carboxylic acid. Reaction could be written as : RCOOH (Carboxylic acid) + HO-R' (alcohol) â RCOOR' (Ester ) Esters can be identified by the presence of -COO- linkage in the organic compound.
The ester is called ethylethanoate, or commonly, ethyl acetate. Esters occur in many plants and are, in. part, responsible for the distinctive odors of those plants and the flavors of their fruits. Esters are commonly used in the preparation of artificial flavors or fragrances. Flavors and fragrances may utilize a single ester or a mixture of esters and other substances to duplicate the odor and flavor of a particular fruit. Some esters that smell like common materials that can be prepared in the laboratory are listed in Table 1. H3C C O H H2 CH3 OH C
