Reactions of esters

WebOct 12, 2024 · The chemical reaction occurring in the formation of the ester is known as an esterification reaction. The reaction that occurs between ethanol and butanoic acid: Ethanol reacts with butanoic acid in the presence of an acid - catalyst and gives ethyl butanoate as ester and water as products. WebAn ethyl acetate ester can be seen depicted as the molecule in the linked image. Esters are created when an alcohol and an acid undergo a condensation process, and the specific structure of this ester consists of an ethyl group that is attached to an acetate group. Esters are made when an alcohol and an acid undergo a condensation reaction.
