To predict the products of the following transesterification reaction. (a) ethyl benzoate + excess isopropanol + HCl Concept introduction: Transesterification is the process of formation of a new ester molecule from the reaction of alcohol and an ester. This is like hydrolysis of ester but here nucleophile is alcohol molecule instead of H 2 O . As alkoxide groups have same basicity, therefore, an excess amount of alcohol is used. The addition of an acid also increases the rate of reaction by protonating the carbonyl oxygen atom. A general transesterification is written as,
