Question

In the given resonating structures, which one is called resonance hybrid?

• A. Structure $I$
• B. Structure $II$
• C. Structure $III$
• D. Both structure $I$ and $II$

Answer 1

Answer: (C)

The ozone, $O_3$ molecule can be equally represented by the structures I and II shown below. In both structures, we have a $O-O$ single bond

Structures $I$ and $II$ represents the two canonical forms while the structure $III$ is the resonance hybrid.
