How will you convert acetaldehyde into the following compounds ?
Butan-1-ol

Explanation

To convert acetaldehyde (CH3CHO) into butan-1-ol (C4H10O), we can follow these steps:

### Step 1: Aldol Condensation
1. **Starting Material**: Take two molecules of acetaldehyde (CH3CHO).
2. **Reaction Conditions**: Add dilute sodium hydroxide (NaOH) as a base.
3. **Process**: The two molecules of acetaldehyde will undergo aldol condensation, resulting in the formation of 3-hydroxybutanal (also known as 3-hydroxybutanol).
- **Chemical Equation**:
\[
