1) Hydration of the carbon-carbon double bond in alpha-pinene can in principle result in four different products (see chart below). However, the reaction sequence you performed is highly regioselective and stereospecific. Draw the mechanism of the hydroboration reaction (the first step of the sequence), and explain which product is expected and why (10 points). CH3 H3C CH3 (1S-()a-pinene...
