Under high pressure, which of the following gases shows more ideality in character:
Correct answer: A. N2
- A. N2
- B. CO2
- C. NH3
- D. SO2
Explanation
Gases behave ideally when intermolecular forces are small. N₂ is non-polar with very weak London forces → behaves most ideally. CO₂, NH₃, SO₂ have stronger intermolecular forces (dipole or hydrogen bonding).

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.
