Given that the compound represented by the model is an intermediate formed by addition of an ester enolate ion to a second ester molecule. The reactant, the leaving group and the product are to be identified. Concept introduction: The Claisen condensation reaction involves a reversible condensation between two molecules of an ester that has α-hydrogen atoms in the presence of one equivalent of a base like sodium ethoxide. The product obtained is a β-keto ester. In the reaction an alcohol molecule is eliminated and the product has an acyl group of one of the reactant molecule attached to the α-carbon of the second molecule. To identify: The reactant, the leaving group and the product involved in preparing the compound represented by the model is an intermediate formed by addition of an ester enolate ion to a second ester molecule.
