Interpretation:
The mechanism for the given reaction has to be completed.
Concept introduction: When two molecules of an ester undergo condensation is called claisen condensation. Like in aldol reaction, in claisen condensation one molecule is a nucleophile and the other molecule is an electrophile.
A claisen condensation reaction is a reversible reaction and occurs in the presence of a strong base.
The first step of claisen condensation is the removal of a proton from alpha carbon by a base and then the addition of enolate ion formed to the second ester molecule forming a β-ketoester.
A crossed-claisen condensation is also a condensation reaction between a
