Aldehydes and ketons have lower boiling points than corresponding alcohols and acids . Explain .

Explanation

To explain why aldehydes and ketones have lower boiling points than corresponding alcohols and carboxylic acids, we can break down the explanation into several steps:

### Step 1: Understanding Molecular Structure
- **Aldehydes** and **ketones** contain a carbonyl group (C=O), while **alcohols** contain a hydroxyl group (–OH) and **carboxylic acids** contain both a carbonyl and a hydroxyl group (–COOH).
- For example, consider propanal (an aldehyde), propanone (a ketone), propanol (an alcohol), and propanoic acid (a carboxylic acid).

### Step 2: Hydrogen Bonding
- Alcohols and carboxylic acids can form hydrogen bonds due to the presence of the –OH group. Hydrogen bonding occurs when a hydrogen atom bonded to a highly electronegative atom (like oxygen) is attracted to another electronegative atom.
