Quizplus · Accepted Answer

The boiling points of isomeric alcohols are determined by both the different number of hydrogen bonds they can form (due to differences in molecular polarity) and the different shapes of the molecules (due to differences in intermolecular forces). Therefore, statement D is the most accurate.
