Answers: 2.25 a) 1-Butanol has dispersion, dipole-dipole and hydrogen bonding intermolecular forces, whereas diethyl ether has only dispersion and dipole-dipole intermolecular forces. Given the presence of hydrogen bonding, the strength of the intermolecular forces is greater in 1-butanol  than in diethyl ether, hence 1-butanol has a higher boiling point. b) Trimethylamine has dispersion and dipole-dipole intermolecular forces, whereas ethylmethylamine has dispersion, dipole-dipole and hydrogen bonding intermolecular forces. Given the presence of hydrogen bonding, the strength of the intermolecular forces is greater in ethylmethylamine than in trimethylamine, hence ethylmethylaminehas a higher boiling point. c) 1-Butanol and 1,3-propanediol have dispersion, dipole-dipole and hydrogen bonding intermolecular forces. However, given the presence of 2 hydroxyl groups which are capable of forming hydrogen bonding interactions, the strength of the intermolecular forces is greater in 1,3-propanediol than in 1-butanol, hence 1,3-propanediol has a higher boiling point.

2.46  When you are asked to determine which molecule has a higher boiling or melting point, you must first provide the intermolecular forces present in each case before explaining why one molecule has a higher boiling or melting point than another. For an example, see the answers provided for question 2.25 above.
