Question

Place the following substances in order of increasing boiling point. He I₂O₂ A) He < I₂ < O₂ B) I₂ < O₂ < He C) O₂ < I₂ < He D) I₂ < He < O₂ E) He < O₂ < I₂

Quizplus · Accepted Answer

Helium (He) has the lowest boiling point due to its weak dispersion forces. Oxygen (O2) has a higher boiling point than helium due to stronger intermolecular forces. Iodine (I2) has the highest boiling point due to its larger size and stronger London dispersion forces.
