Van der Waals forces may arise from three sources. First, the molecules of some materials, although electrically neutral, may be permanent electric dipoles.Because of fixed distortion in the distribution of electric charge in the very structure of some molecules, one side of a molecule is always somewhat positive and the opposite side somewhat negative.

molecules – the greater the intermolecular force the more the liquid will resist flow d. greatest heat of vaporization: H2CO, CH3CH3, CH4 – only polar molecule and so it has dipole-dipole intermolecular forces e. smallest enthalpy of fusion: I2, CsBr, CaO – only nonpolar molecule and so it will require the least amount of energy to melt 3.
in terms of the intermolecular forces between each of the solutes and water. CH2Cl2 is polar, whereas CCl4 is not. Therefore, CH2Cl2 interacts with H2O via dipole-dipole forces, while CCl4 only interacts with water via dipole/induced dipole forces or LDFs, which would be weaker. As a result, CH2Cl2 has a greater solubility.
