Chapter 14. Covalent Bonding: Orbitals Chem 162A Hybridization and the LE Model of Bonding - Lewis structures of molecules - prediction of geometry of molecules - hybrid orbitals (sp 3 , sp 2 , sp, dsp 3 , d 2 sp 3 ) - interpretation of structure and bonding Molecular Orbital Model of Bonding in Molecules - molecular orbital diagrams - bond order - magnetism Molecular Spectroscopy - Electronic Spectroscopy - Vibrational/Rotational Spectroscopies - Nuclear Magnetic Resonance (NMR) Spectroscopy 14.1 Hybridization and the LE Model of Bonding - Assume bonding involves only valence orbitals - Methane, CH 4 : 2s 2 2p 2 (2p: 2p x , 2p y , 2p z )C 1s 1 H Valence orbitalsIsolated atoms H atoms in CH 4 will use 1s orbitals Of the two types of orbitals (2s and 2p) Which will C atoms use for bonding in CH 4 ? - If both are used: 2 different types of C-H bonds (Contrary to experimental facts) - Neither of the "native" atomic orbitals of C atoms are used; instead...
