Mechanism for the given transformation need to be drawn and the reagents used for the given transformation has to be identified. Concept introduction: When compound containing active methylene group is treated with LDA , it undergoes deprotonation at the α carbon to form carbanion. The carbanion can undergo alkylation with any alkyl halide to give the product where the alkyl group is substituted in the α carbon.

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.
