Ozone molecular orbital model

What are the Lewis structures for the two allotropic forms of oxygen How can the paramagnetism of O2 be explained using the molecular orbital model What are the molecular structure and the bond angles in ozone ... 

Using ozone as a model, describe the tt bonding in NO2 using a molecular orbital scheme. 

In the Lewis model, we use resonance forms to represent the two equivalent bonds, hi valence bond theory, it appears that the two oxygen-oxygen bonds should be different. hi molecular orbital theory, however, the ir molecular orbitals in ozone are formed from a linear combination of the three oxygen 2p orbitals and are delocalized over the entire molecule. The lowest energy tt bonding molecular orbital is shown here.
