Are you a chemistry student? Visit A-Level Chemistry to download comprehensive revision materials - for UK or international students! Esters are the derivatives of carboxylic acids in which the hydrogen of carboxylic acid -COOH has been replaced by an alkyl group -R like methyl, ethyl or a benzene ring like phenyl.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. Esters are very important class of acid derivatives because of their uses in many synthetic products such as perfumes, pesticides, solvents etc.

Functional Groups in Organic Chemistry

If it were hydrogen atom, the compound would be a carboxylic acid. Esters occur widely in nature. Unlike carboxylic acids, esters generally have pleasant odors and are often responsible for the characteristic fragrances of fruits and flowers. Once a flower or fruit has been chemically analyzed, flavor chemists can attempt to duplicate the natural odor or taste. Both natural and synthetic esters are used in perfumes and as flavoring agents. Fats and vegetable oils are esters of long-chain fatty acids and glycerol. Esters of phosphoric acid are of the utmost importance to life.

Functional 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 alkoxy group. Glycerides , which are fatty acid esters of glycerol , are important esters in biology, being one of the main classes of lipids , and making up the bulk of animal fats and vegetable oils. Esters with low molecular weight are commonly used as fragrances and found in essential oils and pheromones.

In organic chemistry , a functional group is a substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions. The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition. The reactivity of a functional group can be modified by other functional groups nearby.
