The compounds required for the condensation to synthesise the given compound are to be stated. Concept introduction: In base-catalysed aldol condensation, nucleophilic addition of an enolate ion takes place on a carbonyl group. In first step, an alpha proton is removed to produce enolate ion. It adds to the carbonyl group. In the next step, protonation of alkoxide gives the aldol product.

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
