Brunch IR: esters The carbonyl stretch C=O of aliphatic esters appears from 1750-1735 cm -1; that of α, β-unsaturated esters appears from 1730-1715 cm -1. 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 group. Usually, esters are derived from a substitution reaction of carboxylic acid and an alcohol. Esters are organic chemical compounds whose structure has the general form: where the symbols R1 and R2 represent organic radicals. R 1 and R 2 are often carbon chains that can be either linear or branched and might also have other functional groups attached. Esters are formed through reactions between an acid and an alcohol with the elimination of water.

Protonation of the ester carbonyl makes it more electrophilic. Step 2: The water O functions as the nucleophile attacking the electrophilic C in the C=O, with the electrons moving towards the oxonium ion, creating the tetrahedral intermediate. Step 3: An acid/base reaction. Men kan esters beschouwen alsof ze ontstaan zijn uit een condensatiereactie tussen een alcohol/suiker en een zuur/zuurchloride.
