Intermolecular Forces and Physical Properties

Q. So the question is to rank the volatility of the following molecules from lowest to highest: CH4, CBr4, CH2Cl2, CH3Cl, CHBr3, CH2Br2. So the answer claims that CH4 has the lowest volality, and therefore the strongest IMF but I don't understand why since CH4 has the lowest imf (London dispersion)
