esterZoomA-Z

Subject - Organic Chemistry

In a narrow sense, esters are organic compounds of the formula R-CO-O-R' with R'≠H. Ethylacetate, H3C-CO-O-C2H5, frequently used as solvent, is an important representative of this compound class. Esters can be prepared from carboxylic acids and alcohols or phenols with loss of water.

R-COOH + R'-OH → R-CO-O-R' + H2O

The use of proton acids other than carboxylic acids in the synthetic scheme mentioned above leads to an extended class of esters. Examples are methyl nitrate H3C-O-NO2, an ester of nitric acid, and dimethyl sulfate (H3C)2SO4, an ester of sulfuric acid.
