Ethane and hexane both are nonpolar molecules, but ethane has lower Boiling point than Hexane due to?
Correct answer: D. Strong london forces in hexane due to larger size.
- A. Strong London forces in ethane due to smaller size.
- B. Weak London forces in hexane due to larger size.
- C. Strong London forces in hexane, due smaller size.
- D. Strong london forces in hexane due to larger size.
Explanation
The reason for this is that ethane has weaker intermolecular forces (van der Waals forces) compared to hexane due to its smaller size. This means that less heat energy is required to break the bonds between ethane molecules and convert it from a liquid to a gas, resulting in a lower boiling point. Hexane, on the other hand, has stronger intermolecular forces due to its larger size, requiring more heat energy to overcome these forces and boil. OPTIONS A , B & C are incorrect

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.
