WebExplain, in terms of van der Waals’ forces, the trend in the boiling points of Cl2, Br2 and I2; As you move down group 7, the boiling point increases. 1. The number of electrons increases, leading to an increase in Van der Waals forces between molecules. 2. Therefore more energy is needed to break the bonds, so hence a higher boiling point. top.
