Which of the following statements about hydroboration/oxidation of alkenes is true? A)In hydroboration,the boron atom bonds to the more substituted carbon. B)Hydroboration occurs with anti addition. C)Oxidation occurs with retention of configuration. D)9-BBN does not undergo hydroboration in the same manner as BH₃.

Question

Quizplus · Accepted Answer

Hydroboration/oxidation of alkenes involves the addition of a boron atom to the less substituted carbon in the alkene during the hydroboration step, which occurs with syn addition, not anti addition. During the oxidation step, the boron atom is replaced with a hydroxyl group, and this step occurs with retention of configuration. 9-BBN is a derivative of borane (BH3) used in hydroboration reactions and undergoes hydroboration in a similar manner to BH3, making the statement about 9-BBN incorrect.
