Question

Hybridisation of co32- in block diagram. And confirm about formation of orbitals

Answer 1

Carbonate anion on the basis of the three-electron bond.

Using three-electron bond one can explain structure of carbonate anion, carboxylate anion, oxygen molecule, structure of nitrate anion, nitrogen monoxide, ozone, naphthalene and other organic and non-organic compounds.

It is easy to show, that relation multiplicity = f(L) and Е = f(L), where multiplicity is multiplicity of bond, L – length of bond in Å, Е – energy of bond in kj/mole will be described by function y = a + b/x + c/x² for any types of bond (C-N, C-O, C-S, N-N, N-O, O-O, C-P).
Carbonate anion: CO3(2¯) L (C−O) = 1.29 Å
Carbonate anion, CO3(2¯), Multiplicity (C-O ) (L = 1.29 Å) = 1.370
