Which of the following isomerism is shown by ethyl acetoaceate?
1 Geometrical isomerism
2 Keto-enol tautomerism
3 Enantiomerism
4 Diastereoisomerism
Explanation:
Ethyl acetoaceate contain two functional group one is Ketone and the other are is Ester. Those two functional groups are separated by methylene group. Those methylene hydrogens are highly acidic in nature. So ethyl acetoaceate exhibits Keto- enol tautomerism.
