Quizplus · Accepted Answer

The reaction involves the conversion of an alkene to an alcohol using hydroboration-oxidation. The hydroboration step follows anti-Markovnikov addition, which means that the boron atom will add to the carbon atom with fewer alkyl substituents. In this case, boron adds to the terminal carbon of the double bond. Then, the oxidation step converts the boron substituent to a hydroxyl group. The resulting alcohol will have syn stereochemistry, with both the hydroxyl group and the remaining alkyl group on the same side of the molecule. Option C is the only structure that shows this syn stereochemistry.
