Unformatted text preview: Bonding from p Orbitals Sideways overlap of atomic 2p orbitals that lie in the same direction in space give bonding and antibonding MOs. Molecular Orbital Theory Molecular Orbital Theory 1. No. of MOs = no. of atomic orbitals used. 2. Bonding MO is lower in energy than atomic orbitals. Antibonding MO is higher. 3. Electrons occupy MOs in the order of from lowest to highest energy....
