Why is there a large difference in the boiling points of butanal and butan-1-ol ?

Explanation

To understand the large difference in the boiling points of butanal and butan-1-ol, we need to analyze the molecular structures and the types of intermolecular forces present in each compound.

### Step-by-Step Solution:

1. **Identify the Structures**:
- **Butanal** (an aldehyde) has the structure: CH3CH2CH2CHO. It contains a carbonyl group (C=O) at the end of the carbon chain.
- **Butan-1-ol** (an alcohol) has the structure: CH3CH2CH2CH2OH. It contains a hydroxyl group (–OH) at the end of the carbon chain.
