Acetyl acetone in enol form is more stable in polar aprotic solvents due to
Open in App
Solution
The correct option is A Hydrogen Bonding
In a polar protic solvent like water, the carbonyl group (in keto form) forms hydrogen bonds, which reduce the intramolecular hydrogen bonding of the enol form.
In a polar aprotic solvent, enols form intramolecular hydrogen bond which leads to the formation of a highly stable 6 membered ring. This further reduces the energy of the system.
