Why does PH3 (bp = -87°C) have a lower boiling point than NH3 (bp = -33°C)? O PH3 has larger surface area therefore allowing for stronger London Dispersion Forces. There are strong hydrogen bonds between PH3 molecules and no hydrogen bonds between NH3 molecules The dipole-dipole interactions between NH3 and PH3 make it difficult to separate one from the other. There are strong hydrogen bonds between NH3 molecules and no hydrogen bonds between PH3 molecules
