What is the general reaction for Fischer esterification?
In this reaction there is an equilibrium between the starting materials (carboxylic acid + alcohol) and the products (ester + water).
Cyclic esters can be formed under these conditions, which are known as lactones._{16 nov. 2022}
What is the mechanism of action of esterification?
The mechanism of esterification reactions is the oxygen in an alcohol interacting with a carbocation in an acid.
This complex then transfers the proton from the alcohol to another proton acceptor to act as a leaving group, leaving an -OR group where there was once a hydroxyl (-OH) group.
What is the method of forming an ester in Fischer esterification?
One common way to make an ester is Fischer esterification, where a carboxylic acid and an alcohol react in the presence of an acid catalyst to form the ester and water.
The R group and the carbonyl come from the carboxylic acid, and the alkoxy or aryloxy group with the R' comes from the alcohol.
Esters are produced when carboxylic acids are heated with alcohols in the presence of an acid catalyst.
The catalyst is usually concentrated sulphuric acid.
Dry hydrogen chloride gas is used in some cases, but these tend to involve aromatic esters (ones where the carboxylic acid contains a benzene ring).

The Fischer esterification Mechanism can simply be described as – Protonation of the carbonyl, followed by the nucleophilic attack on the carbonyl, the proton transfer to the OH group, the removal of water and finally the deprotonation step.
