Which of the following should have the lowest boiling point? A)C ₅H ₁₂ B)C ₆H ₁₄ C)C ₈H ₁₈ D)C ₁₀H ₂₂ E)C ₁₂H ₂₆

Question

Quizplus · Accepted Answer

The molecule with the lowest boiling point will have the weakest intermolecular forces. All the molecules have similar molecular weights and similar shapes. However, molecule A has only one hydrogen bond donor and one hydrogen bond acceptor, while the other molecules have multiple hydrogen bond donors and acceptors. Therefore, A will have the weakest intermolecular forces and the lowest boiling point.
