Solution
The correct option is C NH3
The values of vander waals' constant 'a' for the gases O2,N2,NH3 and CH4 are 1.360, 1.390, 4.170 and 2.253 Latmmol2 respectively. The gas which can most easily be liquefied is NH3. Ammonia has high value of the van der waals' constant 'a' which is the measure of the attractive forces present between the gas molecules. Higher is the value of 'a', stronger are the attractive forces present in the gas molecules and more easily the gas can be liquefied.
