Question

Ideal gases and real gases behave in similar ways under certain conditions. However, under specific conditions, real gases deviate from ideal behaviour. Which gas deviates most from ideal behavior?

• A. Nitrogen gas due to the strength of the bond based on the short, triple-bonded nature of the molecule.
• B. Hydrogen gas due to the extremely light molecular mass of the molecule based on the lack of neutrons.
• C. Helium gas due to the lack of interparticle forces based on the non-bonding nature of the monoatomic atom.
• D. Sulfur dioxide gas due to the induced dipole interparticle interaction based on the slightly polar nature of the gas.

Answer 1

Answer: (D)

Sulfur dioxide gas due to the induced dipole interparticle interaction based on the slightly polar nature of the gas.

The deviation from ideal behaviour of real gas depends upon the non-polar nature of the gas.

Here $S{O}_2$ gas is partially polar due to the induced dipole interparticle interaction. Because of this it, there is a force of attraction between the molecule of the gas $S{O}_2$. Thus, it shows maximum deviation from ideal gas behaviour among the given gases.
