Chapter 11, Problem 11.35P

Interpretation Introduction

Interpretation:

The detailed mechanism for the addition of $\text{hexan-3-ol}$ to dihydropyran, showing major product, is to be drawn.

Concept introduction:

The electrophilic addition reaction of an alkene occurs through formation of a more stable carbocation. The electrophilic addition of water across the double bond in an acidic condition produces the alcohol product. The reaction proceeds with proton transfer reaction to form a stable carbocation, followed by the action of water as a nucleophile.
