In the broad sense, the ethyl ester Esters have the general formula RCOOR′, where R may be a hydrogen atom, an alkyl group, or an aryl group, and R′ may be an alkyl group or an aryl group but not a hydrogen atom. (If it were hydrogen atom, the compound would be a carboxylic acid.) Figure 15.4 "The Structure of Esters" shows models for two common esters.

An organic acid has a structure: O This compound, which contains two carbon atoms with a group on one end of the molecule is ethanoic acid, commonly called acetic acid or vinegar (a 5% solution of acetic acid).

Figure 15.5. 1: The Structure of Esters. Esters feature a carbon-to-oxygen double bond that is also singly bonded to a second oxygen atom, which is then joined to an alkyl or an aryl group. The esters shown here are ethyl acetate (a) and methyl butyrate (b). Esters occur widely in nature. What are esters? Esters are derived from carboxylic acids.

Esters feature a carbon-to-oxygen double bond that is also singly bonded to a second oxygen atom, which is then joined to an alkyl or an aryl group.

In chemistry, an ester is a chemical compound derived from an acid (organic or inorganic) in which at least one –OH (hydroxyl) group is replaced by an –O–alkyl group. Usually, esters are derived from a substitution reaction of carboxylic acid and an alcohol .

3 Key Laboratory of Sensing Technology and Biomedical Instrument of Search results for tetramethyl ester at Sigma-Aldrich Esters are another homologous series of organic compounds. They are sweet-smelling and have a fairly complicated structure for this level of|organic chemistry. When ethanol and formic acid react (alcohol and caboxylic acid), ethyl formate is formed.

Esters, like aldehydes and ketones, are polar molecules and so have dipole-dipole interactions as well as van der Waals dispersion forces. However, they do not form ester-ester hydrogen bonds, so their boiling points are significantly lower than those of an How to name esters: Esters may be defined as any of a class of organic compounds produced by reactions between acids and alcohols that involve the elimination of water. This page includes information about naming esters with examples of molecular structures of esters.
