Vedclass · Answer

(A) Dehydration of alcohols in acidic conditions proceeds via the formation of a carbocation intermediate. The ease of dehydration depends on the stability of the carbocation formed and the ability to form a conjugated system. $\beta$-hydroxy carbonyl compounds (aldols) are particularly prone to dehydration because the resulting product is an $\alpha, \beta$-unsaturated carbonyl compound,which is stabilized by conjugation between the $C=C$ double bond and the $C=O$ carbonyl group. Among the given options,option $A$ represents a $\beta$-hydroxyketone (an aldol),which will undergo dehydration most readily to form a stable conjugated system.

Which of the following will be most readily dehydrated in acidic conditions?
