Question

Resonance in carbonate ion $\left( CO _3{ }^{2-}\right)$ is
Which of the following is true?

• A. All these structures are in dynamic equilibrium with each other.
• B. Each structure exists for equal amount of time.
• C. $CO _3{ }^{2-}$ has a single structure i.e., resonance hybrid of the above three structures.
• D. It is possible to identify each structure individually by some physical or chemical method.

Answer 1

Answer: (C)

$CO _3{ }^{2-}$ has a single structure i.e., resonance hybrid of the above three structures.

Answer 2

The correct option is(C): CO 3​2− has a single structure i.e., resonance hybrid of the above three structures.

Resonating structure are hypothetical and resonance hybrid is real structure which is weighted average of all the resonating structures
