Question

Place the following substances in order of decreasing boiling point. He Ar H₂ A) He > H₂ > Ar B) H₂ > He > Ar C) He > Ar > H₂ D) Ar > He > H₂ E) H₂ > Ar > He

Quizplus · Accepted Answer

Boiling points increase with molecular weight and intermolecular forces. Argon (Ar) has the highest boiling point due to its larger atomic size and stronger London dispersion forces compared to helium (He) and hydrogen (H₂).
