Question

The existence of intermolecular forces is supported by the facts:

• A. Non ideality of real gases
• B. Liquefaction of gases
• C. Both (a) and (b)
• D. None of these

Answer 1

The correct option is C Both (a) and (b)

Due to the presence of intermolecular forces, the gases show deviation from ideal behaviour. Also, the presence of intermolecular forces makes the liquefaction of gas possible. Inert gases could not have been liquefied if these intermolecular van der Waal's forces were not present within a molecule.

Hence, the correct option is $\text{C}$
