Solution
Correct Answer:
Anti-Markovnikov alcohol
Hydroboration-Oxidation is a two-step procedure that converts alkenes into alcohols.
- Hydroboration: Borane (BH3 or B2H6) adds across the double bond.
- Oxidation: The organoborane is oxidized using alkaline Hydrogen peroxide (H2O2,OH−).
- Regioselectivity: The overall result is the addition of water across the double bond in an Anti-Markovnikov sense (OH adds to the less hindered carbon).
- Stereochemistry: It is a Syn-addition, where H and OH add to the same face of the alkene.
This medium difficulty chemistry question is from the chapter organic compounds containing oxygen, covering the topic of hydroboration-oxidation. It appeared in the 2025 exam.
