Question

Arrange the following in the increasing order of expected enol content CH3COCH2 CHO, CH3 COCH3 , CH3CHO, CH3COCH2 COCH3  (A)  (B)  (C)  (D)

CH 3- CO - CH 2- COCH 3 has highest enol content due to resonance and formation of six membered ring through intramolecular H-bonding <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/c290c54715d2a8ce05418c0419f6ae7e-.png" /> Also, enol content depends upon the number of substituents on double bond, greater the number of substituents, greater the stability, higher the enol content. Therefore, CH 3 COCH 2 CHO forms next most stable enol
