Question

Give below two statements: One is labelled as Assertion A and the other is labelled as reason R.

Assertion A : Enol form acetone $\left[{\mathrm{CH}}_3{\mathrm{COCH}}_3\right]$ exists in $<0.1\%$ quantity . However, the enol forms acetylacetone $\left[{\mathrm{CH}}_3{\mathrm{COCH}}_2{\mathrm{OCCH}}_3\right]$ that exists in approximately $15\%$ quantity.

Reason R : Enol form of acetylacetone is stabilized by intramolecular hydrogen bonding , which is not possible in enol form of acetone.

In the light of the above statements , choose the correct statement:

• A. A is true but R is false
• B. Both A and R are true but R is the correct explanation of A
• C. A is false but R is true
• D. Both A and R are true but R is not the correct explanation of A
