General Organic Chemistry Question 17

Question 17 - 01 February - Shift 1

Resonance in carbonate ion $(CO_3^{2-})$ is

Which of the following is true?

(1) It is possible to identify each structure individually by some physical or chemical method.

(2) All these structures are in dynamic equilibrium with each other.

(3) Each structure exists for equal amount of time.

(4) $CO_3^{2-}$ has a single structure i.e., resonance hybrid of the above three structures.

Show Answer

Answer: (4)

Solution:

Formula: Resonance

Resonating structure are hypothetical and resonance hybrid is real structure which is

weighted average of all the resonating structures.
