How many resonance structures can be drawn for the molecule O₃? A)1 B)2 C)3 D)4 E)5

Question

Quizplus · Accepted Answer

The molecule O₃ has a total of 28 valence electrons. There are two possible resonance structures that can be drawn. In one of the resonance structures, the sulfur atom can have three lone pairs and a single bond with each of the adjacent oxygen atoms. In the other resonance structure, the sulfur atom can have two lone pairs, a double bond with one of the oxygen atoms, and a single bond with the other oxygen atom. These two resonance structures are shown below. Therefore, the best answer is B.
