$4-$hydroxyhexan$-2-$one

Vedclass · Answer

(D) The ease of dehydration of alcohols under acidic conditions depends on the stability of the carbocation formed after the loss of the water molecule. In the given options, the dehydration of $4$-hydroxyhexan-$2$-one (Option $D$) leads to the formation of a carbocation that is stabilized by hyperconjugation with $5$ $\alpha$-hydrogen atoms. Additionally, the resulting alkene product is conjugated with the carbonyl group, which provides extra stability through resonance. Therefore, $4$-hydroxyhexan-$2$-one undergoes dehydration most readily.

Which one among the following compounds will most readily be dehydrated under acidic condition?
