  • Chain
  • Optical
  • Metamerism
  • Tautomerism
Show Solution

The Correct Option is D

Solution and Explanation

Step 1: Underlying Concept:
Ethyl acetoacetate exhibits keto-enol tautomerism.
Step 2: Explanation:
Ethyl acetoacetate (CH\(_3\)COCH\(_2\)COOC\(_2\)H\(_5\)) exists in equilibrium with its enol form (CH\(_3\)C(OH)=CHCOOC\(_2\)H\(_5\)). This dynamic equilibrium is called tautomerism.
Step 3: Conclusion:
Tautomerism
