हिन्दीGiven van der Waals constants for \( \text{NH}_3, \text{H}_2, \text{O}_2 \) and \( \text{CO}_2 \) are respectively \( 4.17, 0.244, 1.36 \) and \( 3.59 \), which one of the following gases is most easily liquefied?
Correct answer · Option 1
\( \text{NH}_3 \)
Explanation
Greater the value of van der Waals constant 'a', stronger are the intermolecular forces of attraction, and hence more easily the gas is liquefied. \( \text{NH}_3 \) has the highest 'a' value \( (4.17) \).
