Chemistry - Carboxylic acid and their Derivatives Question with Solution | TestHub

Ester gives nucleophilic addition reaction followed by elimination reaction with carbon nucleophile. When carbon nucleophile is of an ester then the reaction is known as Claisen condensation reaction. This reaction is also carried out between ester and a ketone. A successful  Claisen condensation requires an ester with two α hydrogens and an equivalent amount of base rather than a catalytic amount of base.
