Question

Identify the correct statement regarding resonance.

• A. Canonical forms have independent existence
• B. Reasonance affects physical properties but not chemical ones.
• C. Formal charges are present on O atom(s) in $O_3$
• D. At a given moment, half the $O_3$ is present as (I) while the other half as (II), where (I) and (III) are two resonating structures of $O_{3-}$

Answer 1

Answer: (C)

Formal charges are present on O atom(s) in $O_3$

The statement (C) is the correct answer.

(A) Canonical forms do not have independent existence.
(B) Resonance affects physical properties as well as chemical ones.
(C) Formal charges are present on $O$ atoms in $O_3$.
(D) At a given moment, $O_3$ is present in the form of resonance hybrid.
