What is the main product when 2-butyne undergoes hydroboration-oxidation?

What is the main product when 2-butyne undergoes hydroboration-oxidation?

Step 1: Start with 2-butyne, which is a type of alkyne with the formula C4H6.
Step 2: Perform hydroboration by adding borane (BH3) to 2-butyne. This step adds a boron atom to one end of the triple bond.
Step 3: The boron atom attaches to the less substituted carbon atom of the alkyne.
Step 4: Next, perform oxidation by adding hydrogen peroxide (H2O2) and a base (like NaOH). This step replaces the boron atom with a hydroxyl group (OH).
Step 5: The result of this reaction is Butanol, which is an alcohol with the formula C4H10O.
