Explanation

### Step-by-Step Text Solution:

**Step 1: Definition of Hydroboration-Oxidation Reaction**
Hydroboration-oxidation is a two-step chemical reaction that involves the addition of borane (BH3) to an alkene, followed by oxidation to form an alcohol. This reaction is notable for its anti-Markovnikov addition, meaning that the hydrogen atom from borane adds to the more substituted carbon atom of the alkene, while the boron atom adds to the less substituted carbon.

**Step 2: Hydroboration Step**
In the hydroboration step, borane (BH3) reacts with an alkene. For example, consider propene (C3H6). The reaction can be represented as follows:
