Basic Molecular Orbital

Linear Combination of Atomic Orbital (LCAO)

A.O. = Atomic Orbital

M.O. = Molecular Orbital

n atoms have n A.O. and n M.O.

Page 10: Inorganic chemistry

Hydrogen M.O.

H A.O. H A.O.

H2 M.O.

What we can deduce from M.O.

Bond order

Magnetic properties

- Paramagnetic = unpaired electron

- Diamagnetic = no unpaired electron
