In chemistry, an ester is a compound derived from an acid (either 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 ′) Ethyl acetate, for instance, is a commonly used solvent, and dialkyl phthalates are used as plasticizers to keep polymers from becoming brittle. [1] these compounds contain a distinctive functional group.
Estérification : définition et explications

The general structure of an ester is rcoor', where r and r' represent alkyl or aryl groups Esters are derived from the condensation reaction between a carboxylic acid and an alcohol, resulting in the elimination of water.
Key takeaway an ester has an or group attached to the carbon atom of a carbonyl group. In this tutorial you will learn about the basic properties and structure of an ester functional group You will also learn about esterification and its mechanism. This could be an alkyl group like methyl or ethyl, or one containing a benzene ring like phenyl.
