Which compound would have the highest boiling point? A)CH₃CH₂CH₂CH₃ B)CH₂(OH)CH(OH)CH₂OH C)CH₃CH₂CH₂OH D)(CH₃)₂CHOH E)HOCH₂CH₂OH

Question

Quizplus · Accepted Answer

Compound B has the highest boiling point because it has hydrogen bonding between the hydroxyl groups. This increases the strength of intermolecular forces, requiring more energy to break the bonds and thus increasing the boiling point. The other compounds either have weaker intermolecular forces or do not have hydrogen bonding.
