Ester - Definition, Structure, Esterification along with Properties …
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. To put it in simple terms, esters are a group of chemical compounds which are formed by bonding of an alcohol group with a group of organic acids, by losing water molecules.
