Interpretation Introduction

(a)

Interpretation:

The given incomplete reaction is to be completed.

Concept introduction:

Claisen condensation takes place between two esters or between an ester and a ketone. In crossed Claisen condensation reaction, a base abstracts an acidic proton from an α carbon atom of carbonyl compound to form an enolate. This enolate reacts with the carbonyl group of other carbonyl compounds that lead to the formation of β- ketoester.

Interpretation Introduction
