Ketone

Q. Assertion A: Enol form of acetone $\left[C{H}_{3}COC{H}_3\right]$ exists in $<0.1\%$ quantity. However, the enol form of the acetyl acetone $\left[C{H}_{3}COC{H}_{2}OCC{H}_3\right]$ exists in approximately $15\%$ quantity.
Reason R: Enol form of acetyl acetone is stabilized by intramolecular hydrogen bonding, which is not possible in enol form of acetone.
