Answer» SEE all these r non polar and u must know that for non polar more the value of vander waal constant more easy the LIQUEFACTION. ALSO for such molecules value of a directly proportional to their MOLECULAR masses so most moleculer mass is of o2 so it will be most easily liquefied.Explanation:hope u UNDERSTOOD
