4. Consider pure substances composed of the following molecules. For each set, put the molecules in order of increasing boiling point and vapor pressure. CH3(CH2)3OH CH3(CH2)3CH3 CH3(CH2)4CH3 Check/evaluate: How is the strength of the intermolecular forces related to these liquid properties? Once you have prepared your rankings, check to make sure that trend in intermolecular forces and the expected relationship to each property matches. Which of these liquid properties is inversely related to the strength of intermolecular forces (i.e., as intermolecular forces increase, this property decreases)?
