A mechanistic reason for the observed regiospecific addition of the alcohol to dihydropyran is to be proposed. Concept introduction: In hydration of an alkene , the first step involves the protonation of alkene to form an intermediate carbocation. In the next step, the carbocation is attacked by the nucleophile. Finally, deprotonation through a base yields the final product. Resonance structure is a blend of two or more Lewis structures. Resonance structures are represented by a double headed arrow between the structures.
