According to van der waal's equation,
(P+

a
)(V−b)=nRT
The ease of liquefaction of a gas depends on their intermolecular force of attraction which in turn is measured in terms of van der Waal's constant ‘a’. Hence, higher the value of ‘a’, greater the intermolecular force of attraction, easier the liquefaction.
Therefore, order of liquefaction is →
