The intermediates of the given reaction and their synthesis are to be stated. Concept introduction: The Robinson annulation reaction is used for ring formation. It is a combination of Michael addition and aldol condensation reaction. In this reaction, a ketone and methyl vinyl ketone react together to for α , β -unsaturated ketone compound in a cyclohexane ring. In Claisen condensation reaction two esters or one ester and a carbonyl compound react together to form β ketoester and β -diketone compound in the presence of a base.

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
