Which gas among them shows maximum ideal behavior?
Correct answer: C. Helium
- A. Ammonia
- B. Hydrogen
- C. Helium
- D. Radon
Explanation
OPTION A: Ammonia deviates from ideal behavior due to its molecular structure and hydrogen bonding, which influences its behavior.OPTION B: Hydrogen shows some deviation from the ideal behavior due to its low critical temperature and pressure and the influence of intermolecular forces such as hydrogen bonding.OPTION C: Helium is the closest to an ideal gas because unlike other gases helium exists as a single atom, which makes the van der Waals dispersion forces as low as possible. OPTION D: Radon does not show maximum ideal behavior because it has a high molecular weight and is influenced by intermolecular forces such as van der Waals forces.

About Real and Ideal Gases
An ideal gas is modelled as particles with negligible volume and no intermolecular attraction, obeying Boyle's, Charles's and Avogadro's laws through PV = nRT. Real gases deviate from this behaviour, especially at high pressure and low temperature, because particle volume and attractive forces matter; the van der Waals equation explains these corrections.
