Quizplus · Accepted Answer

The hydroboration step involves the addition of borane (BH3) to the alkene, forming an intermediate where the boron atom is attached to one of the carbon atoms in the alkene. This intermediate is then oxidized with hydrogen peroxide and a base to yield the final product, a vicinal diol. The intermediate formed in the first step is therefore a boron-carbon intermediate, which is shown in choice B.
