Which one of the following has highest boiling point?
Correct answer: B. Benzene
- A. Diethyl ether
- B. Benzene
- C. Carbon disulphide
- D. Carbon tetrachloride
Explanation
When we compare the boiling points of different substances, we look at the intermolecular forces between their molecules. In the case of carbon tetrachloride, its molecules have strong intermolecular forces, which require more energy to break and transition from a liquid to a gas state.

About Properties of Liquids
Liquid behavior depends on intermolecular forces, which produce surface tension, viscosity, capillary action and a definite volume without a fixed shape. The topic also covers vapor pressure, evaporation, boiling point and the effect of temperature and external pressure, while distinguishing evaporation at the surface from boiling throughout the liquid.
