(a)
Interpretation: The dicarbonyl compound which is needed to prepare given compound by an intramolecular aldol reaction is to be predicted.
Concept introduction: The Aldol condensation reaction that takes place in the different molecules in presence of strong base is known as intermolecular aldol reactions.
The Aldol condensation reaction that takes place within the same molecule in presence of strong base is known as intramolecular aldol reactions. This reaction takes place within the dicarbonyl compounds in which one carbonyl group forms the enolate that acts as a nucleophile and reacts with second carbonyl group which acts as electrophile.
