Which is the unsaturated carbonyl compound formed in the dehydration of the following b-hydroxy carbonyl compound?

Question

Quizplus · Accepted Answer

In the given b-hydroxy carbonyl compound, dehydration leads to the removal of -OH and -H groups from the adjacent carbon atoms, resulting in the formation of a double bond between the C-2 and C-3 atoms. This results in the formation of an unsaturated carbonyl compound, which is represented by structure I. Structure II does not have a double bond and thus cannot be the unsaturated carbonyl compound formed during dehydration.
