Question

Arrange the following in order of increasing boiling point: RbCl, CH₃Cl, CH₃OH, CH₄. A) CH₃OH < CH₃Cl < RbCl < CH₄ B) CH₃OH < CH₄ < CH₃Cl < RbCl C) RbCl < CH₃Cl < CH₃OH < CH₄ D) CH₄ < CH₃OH < CH₃Cl < RbCl E) CH₄ < CH₃Cl < CH₃OH < RbCl

Quizplus · Accepted Answer

The correct order from lowest to highest boiling point is based on molecular weight and intermolecular forces. Methane (CH₄) has the lowest boiling point due to its small size and lack of polarity. Chloromethane (CH₃Cl) has a higher boiling point due to its larger size and dipole-dipole interactions. Methanol (CH₃OH) has an even higher boiling point because of hydrogen bonding. RbCl, being an ionic compound, has the highest boiling point due to the strong ionic bonds.
