An ester is an organic compound where the hydrogen in the compound's carboxyl group is replaced with a hydrocarbon group. Esters are derived from carboxylic acids and (usually) alcohol. While carboxylic acid has the -COOH group, the hydrogen is replaced by a hydrocarbon in an ester.

Step 2: (a) Identify the alkyl chain making up the carboxylic acid Functional groups are groups of atoms that occur within organic molecules and confer specific chemical properties to those molecules. When functional groups are shown, the organic molecule is sometimes denoted as “R.” Functional groups are found along the “carbon backbone” of macromolecules which is formed by chains and/or rings of carbon atoms with the occasional substitution of an Names and Structures of simple Linear Esters in which R 2 = CH 3, which is known as a "-methyl group" The following table shows the first six members of the homologous series of linear esters that include a -methyl group attached (via a single covalent bond) to the oxygen atom in the chain of the ester molecule.

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, as in the substitution reaction of a carboxylic acid and an alcohol.

The most commonly discussed ester is ethyl ethanoate. In organic chemistry, the most common functional groups are carbonyls (C=O), alcohols (-OH), carboxylic acids (CO 2 H), esters (CO 2 R), and amines (NH 2). It is important to be able to recognize the functional groups and the physical and chemical properties that they afford compounds.

Chime: Ester : There are several centers of interest. The two carbons with all single bonds is the center of a tetrahedral geometry. The center of the ester functional group is the carbon double bond oxygen. A carboxylic acid group and an alcohol group are required to produce an ester. Sulphuric acid is used as a catalyst. CH3COOH + CH3CH2OH ➡ CH3COOC2H5 + H2O The lone pair of electrons on the alcohol group attacks the carbonyl group: ester functional group. R-coo-R.

Esters are found in flowers and fruits which owe their fragrance for these compounds. Esters are very important class of acid derivatives because of their uses in many synthetic products such as perfumes, pesticides, solvents etc. Nomenclature.
