Rank the boiling points of the following compounds from lowest to highest: C₁₂H₂₂O₁₁ (sucrose), O₂, NaF

Question

Quizplus · Accepted Answer

The boiling points of compounds depend on their intermolecular forces. NaF has ionic bonds and strong electrostatic attraction between ions, resulting in a high boiling point. Both O₂ and C₁₂H₂₂O₁₁ (sucrose) have hydrogen bonds and dipole-dipole interactions, but C₁₂H₂₂O₁₁ (sucrose) has more functional groups, leading to stronger intermolecular forces and a higher boiling point compared to O₂. Therefore, the correct ranking is O₂ < C₁₂H₂₂O₁₁ (sucrose) < NaF, which is option C.
