(a) Interpretation: The crossed Claisen product that is formed by the given pair of compounds is to be identified. Concept introduction: In crossed claisen condensation reaction, the base abstracts the acidic proton from α − carbon atom of an ester to form enolate. This enolate reacts with carbonyl compound of other ester that leads to the formation of a β-keto ester . The crossed Claisen condensation always takes place between the two different carbonyl compounds.
