Why O3 bent?

Ozone (O3) is bent due to the presence of lone pairs of electrons on the central oxygen atom, which creates a V-shaped or bent molecular geometry. The molecule consists of three oxygen atoms, with one central atom and two bonded atoms. The lone pairs repel the bonding pairs of electrons, leading to a bond angle of approximately 116.8 degrees. This bent structure is a result of the VSEPR (Valence Shell Electron Pair Repulsion) theory, which predicts that electron pairs will arrange themselves to minimize repulsion.
