The heat of vaporisation of water at 100°C is 40·6 kJ per mole and that of benzene at 80°C is 31kJ per mole. Which out of the two has stronger attractive forces ?
Attractive forces between water molecules are stronger than between benzene molecules. Since the energy required to vaporisation of the water is more than that of benzene.
