Question

Write a detailed note on esters.

Answer 1

n 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.[1] Usually, esters are derived from a carboxylic acid and an alcohol.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. Phosphoesters form the backbone of DNAmolecules. Nitrate esters, such as nitroglycerin, are known for their explosive properties, while polyesters are important plastics, with monomers linked by ester moieties.

Answer 2

the reaction between an alcohol and an acid is called esterification.
And thus formed is known as ester

They are sweet smelling substance used in perfumes.

The opposite reaction of ester is known as saponification.
