Question

Assertion A : Enol form of acetone $\left[\mathrm{CH}_3 \mathrm{COCH}_3\right]$ exists in $<0.1 \%$ quantity. However, the enol form of acetyl acetone $\left[\mathrm{CH}_3 \mathrm{COCH}_2 \mathrm{OCCH}_3\right]$ 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. Choose the correct statement :

Select the correct option:

A

A is false but R is true

B

Both A and R are true and R is the correct explanation of A

C

Both A and R are true but R is not the correct explanation of A

D

A is true but R is false
