As you can imagine, with weaker IMF, you have higher equilibrium vapor pressures, and the energy required to evaporate a liquid (the enthalpy of vaporization, ?Hvap) is lower, and the boiling point is therefore lower. Conversely, the stronger the IMF, the higher the ?Hvap and the lower the equilibrium vapor pressure and the higher the boiling point. Which substance in each pair has the highest vapor pressure at a given temperature?A: C2H6 or C4H10 B: CH3CH2OH or CH3CH2Cl C: H2O or H2SeC2H6, CH3CH2OH, H2OC2H6, CH3CH2Cl, H2SeC4H10, CH3CH2Cl, H2Se C2H6, CH3CH2Cl, H2OC4H10, CH3CH2OH, H2O
