Question

explain why co3 2 negative ion cannot be represented by singl lowis structure.how can it be best represented

Answer 1

In CO32- ion, resonance of electrons occur i.e. the electrons are not fixed at one position but are delocalised. Therefore, it cannot be represented by a single lewis structure. It can be best represented in the form of resonance hybrid. The resonating structures are shown below :

The structure in the square brackets is the resonance hybrid of CO32-;
