1. $\mathrm{CH}_{3} \mathrm{COCH}_{2} \mathrm{COCH}_{3}$

2. $\mathrm{CH}_{3} \mathrm{COCH}_{3}$

3. $\mathrm{CH}_{3} \mathrm{COCH}_{2} \mathrm{CONH}_{2}$

4. $\mathrm{CH}_{3} \mathrm{COCH}_{2} \mathrm{COOC}_{2} \mathrm{H}_{5}$

Correct Option: 1

Solution:

Solution

Due to intramolecular H-bonding and resonance stabilisation enol content is maximum
