Question

Arrange the following substances in decreasing order of their boiling points:

• A. Water, ethanol, acetone
• B. Ethanol, acetone, water
• C. Acetone, water, ethanol
• D. Water, acetone, ethanol

Hint:

Boiling point is influenced by the nature of intermolecular forces: hydrogen bonding leads to higher boiling points, while weaker forces like dipole-dipole interactions result in lower boiling points.
