1 Chap 2 1. Bonding. a) e’ described as waves, a wave function. Linear combination of atomic orbits- LCAO Atomic orbitals combine to and overlap to give standing waves. Covalent bonding (LCAO)- two non-metals. Ionic bonding- metal, non-metal Bond length- stability of covalent bonds dependent on max overlap and least amount of electrostatic repulsion. b) Two types of bonds, s and p . 1) sigma bond (single bond)- can add destructively or constructively. Constructively- bonding molecular orbital (bonding mo) s Destructively- anti-bonding molecular orbital. (Anti-bonding mo) s* energy radius 1s 1s bonding anti-bonding

2 2) p bond, double and triple bonds. (show triple bomnds.) 2. Orbital Theory- explains VSPER- Review orbital shapes a) sp hybrid- 2 hybrid orbitals form a combined orbital on the same atom. Show overhead. Start with sp so get two sp hybridized orbits. b) sp 2 - hybrid- get 3 hybrid orbitals c) sp 3 - get 4 hybrid orbitals. Relate to VSPER theory to determine molecular geometry. Sigma bonds determine geometry.
