The VSEPR model predicts the O-O-O bond angle in O₃ to be A)90°. B)109.5°. C)less than 120° but greater than 109.5°. D)120°.

Question

Quizplus · Accepted Answer

O₃ has a trigonal planar electron domain geometry with two lone pairs on the sulfur atoms and one bonding pair between each oxygen and sulfur. According to VSEPR theory, lone pairs take up more space than bonding pairs, resulting in a decrease in the bond angle. Therefore, the O-O-O bond angle in O₃ is expected to be less than 120° but greater than 109.5°, making choice C the correct answer.
