Mechanism for the given type of decarboxylation reaction has to be proposed and it should be compared with the mechanism of decarboxylation of β − k e t o a c i d Concept introduction: Carboxylic acids contain a carbonyl attached to a hydroxyl group as shown below, If carboxylic acid is heated to a very high temperature then of carbon dioxide will be eliminated from it this reaction is known as decarboxylation . Simple carboxylic acids do not decarboxylate readily. Decarboxylation of β − k e t o a c i d is shown below, The mechanism of thermal decarboxylation involves two processes, (i) Redistribution of electrons in a cyclic transition state. (ii) Cyclic transition state possesses keto-enol tautomerism.

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.
