Chapter 8.8, Problem 15P

Hydroboration–oxidation of $\text{α-pinene}$, like its catalytic hydrogenation (Problem $8.3$), isstereoselective. Addition takes place at the less hindered face of the double bond, and a singlealcohol is produced in high yield ( $89\%$). Suggest a reasonable structure for this alcohol.

Catalytic hydrogenation of $\text{α-pinene}$ (a constituent of turpentine) is $100\%$ stereoselective and gives only compound A. Explain using the molecular model of $\text{α-pinene}$ to guide your reasoning.
