Compare the results of hydroboration oxidation and mercuric ion-catalysed hydration for
2-butyne

Explanation

To compare the results of hydroboration-oxidation and mercuric ion-catalyzed hydration for 2-butyne, we will analyze each reaction step by step.

### Step 1: Hydroboration-Oxidation of 2-Butyne

1. **Hydroboration**:
- 2-butyne (CH₃C≡CCH₃) is treated with borane (BH₃) in the presence of tetrahydrofuran (THF).
- The triple bond (C≡C) undergoes hydroboration, where BH₃ adds across the triple bond.
- According to the anti-Markovnikov rule, the boron atom (BH₂) attaches to the less substituted carbon (the one with more hydrogen atoms), while hydrogen (H) attaches to the more substituted carbon.
