The compound drawn is acetone. Four other carbonyl compounds are shown beside the options. Select ALL the structures that have a higher enol content than acetone.

Acetylacetone (about 80% enol) and ethyl acetoacetate (about 8% enol) are 1,3-dicarbonyl compounds whose enols are conjugated and chelated. Acetone has about $10^{-6}$ percent enol. Ethyl acetate and N,N-dimethylacetamide have much lower alpha-acidity than a ketone (resonance of the ester/amide group), so their enol contents are lower than that of acetone.
