From the following, identify the incorrect statement regarding gas having high value of coefficient of attraction.
Correct answer: A. Easy to be liquified
- A. Easy to be liquified
- B. Having higher critical temperature
- C. Less soluble in water
- D. None
Explanation
A gas having high value of coefficient of attraction is tough to be liquified. It is because, the repulsive forces become more significant and the attractive forces become less dominant. Hence these gases are difficult to be condensed.

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.
