QuestionChemical bonding / resonance, delocalisation
In SO₃, one p-orbital and two d-orbitals are used in S=O π-bond formation. However, all S=O bond lengths are identical. This is due to
- (a) involvement of equivalent hybrid orbitals in π-bonding
- (b) considerable polarity in bonds
- (c) delocalization of π-bonds in the molecule
- (d) ionic covalent resonance in the molecule
