Explain why CO₃^2– ion cannot be represented by a single Lewis structure. How can it be best represented?

This is a Short Answer Type Questions as classified in NCERT Exemplar

Ans: The carbonate ion CO₃^2- can be best represented by its resonating structures. The carbonate ion cannot be represented by a single Lewis structure because the three carbon oxygen bond lengths are the same. This cannot be shown by a single Lewis structure. For showing the similar lengths of all the carbon to oxygen bonds three hybrid structures are constructed which are in resonance with each other.
