Which of the following compounds will behave least like an ideal gas at low temperatures? A)He B)SO₂ C)H₂ D)N₂ E)F₂

Question

Quizplus · Accepted Answer

SO₂, H₂, N₂, and F₂ are all larger, more complex molecules compared to He. At low temperatures, the intermolecular forces between the molecules become more significant, causing them to deviate from ideal gas behavior. The larger and more complex the molecule, the stronger the intermolecular forces and the more it deviates from ideal gas behavior. Therefore, B, which is the largest and most complex molecule among the choices, will behave least like an ideal gas at low temperatures.
