Concept explainers
Interpretation:
Incorrect characterization of lactone has to be chosen among the given options.
Concept Introduction:
Esters are prepared by condensation of
Esterification reaction is the one in which the carboxylic acid is condensed with an alcohol (or phenol) in presence of strong acid catalyst to produce ester. The general reaction scheme can be given as,
In the above reaction, hydroxyl group is lost from carboxylic acid and hydrogen is lost from alcohol molecule to form water as the byproduct.
If the considered compound is a hydroxyacid, then there is a possibility of intermolecular esterification reaction. The product obtained in this case is a cyclic ester. Cyclic esters contain an oxygen atom in the ring and a carbonyl group also.
