A mechanism for the given reaction has to be proposed. Concept introduction: The Michael addition of a ketone and enolate to an α , β - unsaturated ketone gives δ - diketone as a final product. When the conjugate addition takes place under strongly acidic or basic conditions then δ - diketone undergoes a spontaneous intramolecular aldol condensation followed by dehydration to form a six membered ring compound commonly known as cyclohexenone. This synthesis is called as the Robinson annulation.

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

Interpretation:

A mechanism for the given reaction has to be proposed.

Concept introduction:

The Michael addition of a ketone and enolate to an α,β- unsaturated ketone gives δ- diketone as a final product. When the conjugate addition takes place under strongly acidic or basic conditions then δ- diketone undergoes a spontaneous intramolecular aldol condensation followed by dehydration to form a six membered ring compound commonly known as cyclohexenone. This synthesis is called as the Robinson annulation.
