The experimentally determined van der Waals constant '' values for , , , and are , , , and respectiv — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

The van der Waals constant '$a$' is a direct measure of the magnitude of intermolecular attractive forces between the gas molecules. The higher the value of '$a$', the stronger the intermolecular forces, making it easier to pull the molecules together into the liquid phase. Since $SO_2$ has the highest '$a$' value ($6.72$), it is the most easily liquefied.
