The order of stability of the following tatutomeric compound is

• A

  I $>$ II $>$ III
• Correct answer
  B

  III $>$ II $>$ I
• C

  II $>$ I $>$ III
• D

  II $>$ III $>$ I

Solution

The rolls of $\beta$-dicarbonyl compounds are more stable because of conjugation and intramolecular $\mathrm{H}$-bonding. Thus, the order of

Hence, the correct answer is option: 'B'.
