Review of Lecture 19: MO Theory: an attempt to understand bonding from an orbital perspective solutions to Schrodinger Equation for the system H 2 + Provides a more “global” approach. Or from AO’s, . Unlike 2 , can be positive or negative…the text doesn’t admit that until later in the chapter. MO’s can be sums or differences of AO’s; there are same number of MO’s as AO’s used in their construction. s s ; bonding or antibonding. Reading: Chapter 9 Review Sessions: Sat 2pm; Sun 4pm here! NO GRAPHING CALCULATORS ALLOWED!
MO formation for Li, Be, B, C and N diatomics from n=2 orbitals MO formation for O, Fl and Ne diatomics from n=2 orbitals note reversal of energy ordering of 2p and 2p orbitals
For heteronuclear diatomics…a few subtle modifications.Which energy ordering? .
