(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.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
