ester


Ester Definition. Esters are the derivatives of carboxylic acids in which the hydrogen of carboxylic acid (-COOH) has been replaced by an alkyl group (-R) like methyl, ethyl or a benzene ring like phenyl. The ester functional group may be represented as -COOR. Esters are found in flowers and fruits which owe their fragrance for these compounds.



Naming Esters Definition of Esters: Esters are organic chemical compounds whose structure has the general form: where the symbols R1 and R2 represent organic radicals. R 1 and R 2 are often carbon chains that can be either linear or branched and might also have other functional groups attached.



Esters are common solvents. Ethyl acetate is used to extract organic solutes from aqueous solutions—for example, to remove caffeine from coffee. It also is used to remove nail polish and paint. Cellulose nitrate is dissolved in ethyl acetate and butyl acetate to form lacquers. The solvent evaporates as the lacquer “dries,” leaving a thin.



The chemical formulas of organic esters formed from carboxylic acids and alcohols usually take the form RCO 2 R' or RCOOR', where R and R' are the organyl parts of the carboxylic acid and the alcohol, respectively, and R can be a hydrogen in the case of esters of formic acid.



In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R). Analogues derived from oxygen replaced by other chalcogens belong to the ester category as well.
