The necessary curved arrows are to be added and tetrahedral intermediate are to be identified. The name of the elementary step that takes place is to be written. Concept introduction: When an ester is treated with sodium methoxide, a different ester is produced. This is an example of a transesterification reaction, so called because one ester is converted into another. The mechanism for this transesterification is typical of reactions involving a nucleophile and a carboxylic acid derivative. It is called a nucleophilic addition-elimination mechanism, which describes the two steps that take place.

Answer 1

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
