Problem
The table shown here lists the molar heats of vaporization for several organic compounds.

Compound Heat of vaporization (kJ/mol)
CH3CH2CH3 19.0
CH3CH2CH2CH2CH3 27.6
CH3CHBrCH3 31.8
CH3COCH3 32.0
CH3CH2CH2Br 33.6
CH3CH2CH2OH 47.3

Explain these comparison in terms of the nature of the intermolecular forces at work. (You may find it helpful to draw out the structural formula for each compound.)
