How to know what has the lowest boiling point? The one with the weakest IMF will have the lowest boiling point. CH4 has only dispersion forces while all the others have dispersion PLUS either dipole-dipole (HCl, H2S, NH3), and/or hydrogen bonding (NH3). So, CH4 will have the lowest boiling point.
How do you determine lowest boiling point? Intermolecular forces (IMFs) can be used to predict relative boiling points. The stronger the IMFs, the lower the vapor pressure of the substance and the higher the boiling point. Therefore, we can compare the relative strengths of the IMFs of the compounds to predict their relative boiling points.
