The two compounds that are the correct enol tautomers of 2-butnone are the structures shown in Option B.
<h3>What is Keto Enol Tautomerism?</h3>
Isomerism is a situation in which two compounds have the same molecular formula but do not have the same structural formula. This occurs because the atoms in the molecule are arranged differently in space. One of the types of isomerism that we have is the Keto Enol Tautomerism. The Keto Enol Tautomerism occurs between the Keto and the enol forms of a compound via the movement of electrons. It is common in ketone compounds.
In this case, we can see that the compound 2-butanone can give rise to two enol compounds that have the same molecular formula as the 2-butanone.
The two compounds that are the correct enol tautomers of 2-butnone are the structures shown in Option B.
