Vedclass · Answer

(A) Acid-catalyzed hydration involves the formation of a carbocation intermediate. The reactivity depends on the stability of the carbocation formed after the loss of water or the protonation of the double bond. In the case of $1,2,3,4$-tetrahydronaphthalen-$1$-ol,the dehydration leads to the formation of a carbocation that is stabilized by resonance with the benzene ring,eventually leading to the formation of naphthalene,which is a highly stable aromatic system. Therefore,the compound that can form the most stable carbocation intermediate or lead to the most stable product is the most reactive. Among the given options,the structure in option $A$ is the most reactive because its dehydration leads to the formation of the stable aromatic compound naphthalene.

Which of the following compounds is most reactive toward acid-catalyzed hydration?
