Question

Quizplus · Accepted Answer

The compound SO₂ does not correspond to any known chemical formula, and thus it is likely a mistake. Assuming it is meant to represent a valid compound, the only answer choice with a significant molecular weight (and therefore potential for intermolecular forces) is B. The other choices are all noble gases, which have weak intermolecular forces and behave most like ideal gases at low temperatures.
