a and b are van der Waals constants for gases. Chlorine is more easily liquefied than ethane because
A.a and b for Cl2 > a and b for C2H6
B.a and b for Cl2 < a and b for C2H6
C.a for Cl2 > a for C2H6 but b for Cl2 > b for C2H6
D.a for Cl2 > a for C2H6 but b for Cl2 < b for C2H6✓ Correct
Explanation
a for Cl2 > a for C2H6 but b for Cl2 < b for C2H6 Since there is stronger intermolecular interaction present in Cl2. Cl2 is more easily liquefied.
