From the graph given below compare the intermolecular forces of attraction in A and B.

Explanation

At extermely low pressure, all the gases behave almost ideally. From the graph, it is known that as pressure increases, PV decreases showing that with increasein pressure the intermolecular spaces between molecules of B can be decreased to a great extent. This is possible when the intermolecular forces between the molecules are more. At a certian stage PV reaches minimum and then increases showing that further increase in pressure cannot decreae the volume to that extent. While in A though the intermolecular spaces are more, the decrease in volume of'A ' with the increase of pressure is lesser than ideal gas. This shows that intermolecular forces of attraction of A are less.
