Consider the acid-catalyzed cleavage of propylene oxide with 1-propanol. Provide abbreviated structural formulas for the protonated epoxide substrate and of 1-propanol, of the intermediate formed by addition of 1-propanol to the epoxide, and of the final product. Use curved arrows to describe the mechanism.
