$CH_3COCH(OH)CH_2CH_3$

Vedclass · Answer

(C) Acid-catalyzed dehydration of alcohols proceeds via the formation of a carbocation intermediate. The rate of dehydration depends on the stability of the carbocation formed after the loss of water. In option $C$,the structure is $CH_3COCH(OH)CH_2CH_3$. Upon protonation and loss of water,it forms a carbocation at the $\alpha$-position relative to the carbonyl group $(CH_3COC^+HCH_2CH_3)$. This carbocation is stabilized by resonance with the adjacent carbonyl group,making it significantly more stable than the carbocations formed from the other options. Therefore,the compound in option $C$ will dehydrate most readily.
