Vedclass · Answer

(A) The enol content in cyclic $\beta$-diketones is determined by the stability of the enol form,which is stabilized by intramolecular hydrogen bonding and the extent of conjugation. However,the formation of the double bond within the ring system introduces angle strain. As the ring size decreases,the angle strain in the enol form increases,which destabilizes the enol. Molecule $I$ consists of two six-membered rings,molecule $II$ consists of a six-membered and a five-membered ring,and molecule $III$ consists of two five-membered rings. The angle strain increases in the order $I Consequently,the stability of the enol form decreases in the order $I > II > III$. Thus,the decreasing order of enol content is $I > II > III$.

The correct decreasing order in the enol content of the following molecules is:
