"Webb29 dec. 2024 · But it is due to a lone pair present on the central oxygen (O) atom that lone pair-bond pair repulsions decrease the bond angle by tilting the O=O and O-O bonds towards each other. Thus, the O=O-O bond angle becomes 116.8° in the asymmetrical bent shape of the ozone (O3) molecule. The average O=O bond length is 128 pm. " - Shape of harf molecule
