Answer

To convert propene (CH3-CH=CH2) to 1-propanol (CH3-CH2-CH2OH), we can use the hydroboration-oxidation reaction. Here’s a step-by-step solution:

### Step 1: Identify the starting material and the desired product
- **Starting material**: Propene (CH3-CH=CH2)
- **Desired product**: 1-Propanol (CH3-CH2-CH2OH)

### Step 2: Choose the appropriate reagent
The reagent required for the conversion of propene to 1-propanol is **B2H6** (diborane) followed by **H2O2** (hydrogen peroxide) in the presence of **NaOH** (sodium hydroxide).

### Step 3: Hydroboration of Propene
1. **Reaction with B2H6**:
- Propene reacts with diborane (B2H6).
- The boron atom from B2H6 adds to the less substituted carbon of the double bond (the terminal carbon), while a hydrogen atom adds to the more substituted carbon.
- This results in the formation of trialkylborane.

### Step 4: Oxidation of Trialkylborane
2. **Oxidation with H2O2 and NaOH**:
- The trialkylborane formed in the previous step is then treated with hydrogen peroxide (H2O2) in the presence of sodium hydroxide (NaOH).
- This reaction leads to the replacement of the boron atom with a hydroxyl group (-OH), yielding 1-propanol.

### Step 5: Final product
- The final product after the hydroboration-oxidation reaction is 1-propanol (CH3-CH2-CH2OH).

### Conclusion
The reagent required to convert propene to 1-propanol is **B2H6 followed by H2O2 in NaOH**.
