Among aldehydes and ketones, which one will have more boiling point?
Understand the Problem
The question is asking to compare the boiling points of aldehydes and ketones, seeking to determine which of the two classes of organic compounds typically has a higher boiling point.
Answer
Ketones have a higher boiling point than aldehydes.
Ketones generally have a higher boiling point than aldehydes of similar molecular mass because the carbonyl group in ketones is more polarized, leading to stronger intermolecular forces.
Answer for screen readers
Ketones generally have a higher boiling point than aldehydes of similar molecular mass because the carbonyl group in ketones is more polarized, leading to stronger intermolecular forces.
More Information
The higher polarity in ketones due to their carbonyl group leads to stronger dipole-dipole interactions, making them have higher boiling points compared to aldehydes.
Tips
A common mistake is not considering the molecular interactions, leading to incorrect assumptions about boiling points based only on molecular weight.
