Question

Draw resonating structure of CO32- & state the hybridization of carbon in it.

Answer 1

Answer:

The carbonate ion, CO3 2- is has a trigonal planer geometry , the carbon is sp2 hybridized.

Answer 2

Answer:

Resonating structure of  $\[CO_3^{2 - }\]$ is as follows

Explanation:

One structure of a molecule is unable to explain all properties of the molecule. Some properties are explained by resonance, some properties are explained by hyperconjugation etc.

Resonance is the delocalization of $\pi$ electrons in a molecule. But during making the resonating structure total number of $\pi$ electrons must remain the same. There should be no new sigma bond formation.
