Sixteen electrons are present in the Lewis structure of which of the following molecules?

Question

Quizplus · Accepted Answer

Both A and C have 18 electrons in their Lewis structures, while B has 20 electrons. However, molecule B is resonance stabilized and can exist in multiple forms with different electron distributions. Therefore, it is possible for B to have a Lewis structure with 16 electrons. Hence, the correct answer is D, more than one correct response.
