Which of the following has the highest boiling point? A) CH₃CH₂CH₂CH₂CH₂Br B) CH₃CH₂CH₂CH₂CH₂I C) CH₃CH₂CH₂CH₂CH₃ D) CH₃CH₂CH₂CH₂CH₂F E) CH₃CH₂CH₂CH₂CH₂Cl

Question

Quizplus · Accepted Answer

The boiling point of a compound depends on its intermolecular forces. The compound with the strongest intermolecular forces will have the highest boiling point. The compound in choice B, which is CH3CH2CH2CH2CH2I, has the highest boiling point because it is a larger molecule with more atoms and stronger London dispersion forces than the other compounds. The other compounds in the choices are either smaller or have weaker intermolecular forces.
