Sulfur dioxide, SO2\text{SO}_2SO2, is a toxic gas emitted during volcanic eruptions. Within each molecule, the sulfur atom is joined to two oxygen atoms by covalent bonds.
Explain, in terms of structure and bonding, why sulfur dioxide has a low boiling point (−10∘C-10^\circ\text{C}−10∘C) and exists as a gas at room temperature.
