Place the substances in order of increasing boiling point. BeF₂ SF₂ Ar

Question

Quizplus · Accepted Answer

Argon (Ar) is a noble gas with a very low boiling point due to its weak van der Waals forces. Beryllium fluoride (BeF2) and sulfur hexafluoride (SF6) are both molecular compounds, but SF6 is a larger molecule with stronger van der Waals forces than BeF2, leading to a higher boiling point. Therefore, the order from lowest to highest boiling point is Ar < BeF2 < SF6.
