The three molecules,  CH3Br, CH3Cl, and CH3F, have tetrahedral structures and are polar so they have both the London dispersion and the dipole-dipole forces between their molecules. Rank the three molecules in order of increasing boiling point, assuming that dipole-dipole forces are the predominant intermolecular force existing between their molecules.
