2. List the following molecules in order of increasing boiling point: Br2, F2, I2, Cl2, Answer Higher boiling points will correspond to stronger intermolecular forces. Go through the list above. 1. None of these have hydrogen bonding. 2. None of these have dipoles. 3. Bigger molecules will have stronger London dispersion forces. 1) CH4 has weak dispersion forces and CH3Cl has dipole -dipole forces. intermoleculuar forces strength increases boiling point increases and vapour pressure decreases. so that CH3Cl has greater boiling point (BP) and lower vapour pressure. 2) CH3OH and CH3CH2CH2OH both have hydrogen bonds but CH3CH2CH2OH will have aditionally more degree of ... Give it 4 points for ionic bonds, 3 points for hydrogen bonds, 2 points for dipole bonds, and 1 point for dispersion bonds. Given the example, PF4 has dipole bonds, so it gets 2 points. Meanwhile, CF4 has dispersion bonds, so it gets 1 point. Since PF4 has more points than CF4, it has a higher boiling point. Boiling Point.
