Document Summary
Che2a lecture 18 molecular orbital theory for bonding. Mo theory vs vb theory: mo theory is more accurate, but also more complicated, mo theory is based on the concept of the molecular orbital. Vb theory is based on the concept of the atomic orbital: mo theory is particularly useful for describing delocalized -bonding in molecules. Vb theory is useful in describing localized -bonding in molecules because of its simplicity. Bonding molecular orbitals: when the amplitudes of atomic wave functions, in other words atomic orbitals, are added, the electron density between the nuclei is maximum. Antibonding molecular orbitals: result when the amplitudes of atomic wave functions are subtracted, the electron density between the nuclei is zero, said to be a node between the two nuclei https://www. chemguide. co. uk/analysis/uvvisible/bonding. html. Bonding molecular orbitals: the combination of two p atomic orbitals can result in the formation of two molecular orbitals and two molecular orbitals.
