The O-S-O bond angle in SO₂ is slightly less than ________.

Question

Quizplus · Accepted Answer

The SO₂ molecule has a linear shape with the S-O-S bond angle being 180°. The O-S-O bond angle would be determined by the lone pairs of electrons on the oxygen atoms. Since there are two lone pairs on each oxygen, they repel each other decreasing the bond angle. The ideal bond angle for trigonal planar (sp2 hybridized) atoms is 120°, which is slightly less than the 180° angle in SO₂. Therefore, the correct answer is C) 120°.
