Which of the following would have the highest boiling point? A)CH₃CH₂-O-CH₂CH₂-O-CH₃ B)CH₃-O-CH₂CH₂CH₂-O-CH₃ C)HO-CH₂CH₂CH₂CH₂-OH D)CH₃CH₂-O-CH₂-O-CH₂CH₃

Question

Quizplus · Accepted Answer

The compound C has two polar -OH groups, which can form strong intermolecular hydrogen bonds. This increases the boiling point of the compound as it requires more energy to break these hydrogen bonds. The other compounds do not have as many polar functional groups, and therefore have weaker intermolecular forces and lower boiling points.
