Condensation product should be identified Concept introduction: Claisen condensation is a process where a carbon-carbon bond is formed when reaction occurs between two esters or one ester and carbonyl compound in presence of a strong base to form a β -keto ester or a β -diketone, respectively Deprotonation of α carbon to form ester enolate Attach of enolate ion with the carbonyl of ester or ketone ( nucleophilic attack ) Loss of alkoxide ion to reform carbonyl To predict : The condensation product when the given ester is treated with sodium ethoxide

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
