Unformatted text preview: 1 1 Covalent Bonding: Orbitals Todays Lecture 14.3 Bonding in Homonuclear Diatomic Molecules 14.4 Bonding in Heteronuclear Diatomic Molecules 14.5 Combining the LE and MO Models 1 More Homonuclear Diatomic Molecules consider B 2 the boron atom has a 1s 2 2s 2 2p 1 electron configuration (i.e. valence 2s and 2p atomic orbital can participate in MO valence 2s and 2p atomic orbitals can participate in MO formation) weve already looked at the formation of MOs from 2s atomic orbitals [combination of 2s atomic orbitals of each B gives MOs (one bonding and one antibonding)] what about the MOs from the combination of p orbitals? 2 what about the MOs from the combination of p orbitals? this gives both and type MOs - bonding and antibonding note that for now well assume that the 2s and the 2p atomic orbitals do not mix 2 2 Overlap of p Orbitals two boron atoms with three mutually perpendicular 2p orbitals Fig. 14.35 3 MO MOs - electron probability lies above and below the plane between the nuclei...
