Question

Write resonance structure CO3

-2

.​

Answer 1

Answer:

The carbonate (CO2-3)

Explanation:

Unlike O3, though, the actual structure of CO32− is an average of three resonance structures. ... Carbon has 4 valence electrons, each oxygen has 6 valence electrons, and there are 2 more for the −2 charge. This gives 4 + (3 × 6) + 2 = 24 valence electrons.

Answer 2

The resonating structures of ion are shown below. Carbonate ion contain one carbon and three oxygen atoms. In the above structures, delocalization of electron pair takes place from one oxygen atom to other resulting in the formation of three resonance structures.
