Which of the following has the lowest value of the Van der Waals constant?
Correct answer: A. H2
- A. H2
- B. N2
- C. CO2
- D. CI2
Explanation
It has nonpolar bonds between its component atoms. This results in a weaker attraction between a nucleus. Moreover, the size of H2 is smaller so fewer London forces are present.

About Gases
Gas behaviour is explained through the kinetic molecular theory and the relationships among pressure, volume and temperature. Work includes STP, Boyle's and Charles's laws, absolute zero, the ideal gas equation, and the distinction between ideal and real gases, especially the effects of intermolecular forces and molecular volume.
