MO Diagrams for Diatomic Molecules
www.chem.uci.eduSummary MO Theory • LCAO-MO Theory is a simple method for predicting the approximate electronic structure of molecules. • Atomic orbitals must have the proper symmetry and energy to interact and form molecular orbitals. • Photoelectron spectroscopy provides useful information on the energies of atomic orbitals. • Next we’ll see that symmetry will help us treat larger …

LEWIS STRUCTURES General Rules for Drawing Lewis Structures
clas.sa.ucsb.edu7. In drawing Lewis structures for relatively small molecules and polyatomic ions, the structures tend to be more stable when they are compact and symmetrical rather than extended chains of atoms. EXAMPLE: Write the Lewis structure for CH2O where carbon is the central atom. Step 1: Determine the total number of electrons available for bonding.
