What is the main product when propene undergoes hydroboration-oxidation?

Step 1: Start with propene, which is a three-carbon alkene with a double bond between the first and second carbon atoms.
Step 2: Perform hydroboration by adding borane (BH3) to propene. This step adds a boron atom to the less substituted carbon (the first carbon) and a hydrogen atom to the more substituted carbon (the second carbon).
Step 3: After hydroboration, you have an organoborane intermediate. Next, perform oxidation by adding hydrogen peroxide (H2O2) and a base (like NaOH).
Step 4: The oxidation step replaces the boron atom with a hydroxyl group (OH) on the first carbon, resulting in propan-2-ol, which is an alcohol.
