Lewis Structures Hybrid Orbitals Shapes of Molecules (Common  Stereochemistries in Main Group  Compounds) 

 Lewis Structures  Concepts and Vocabulary:  Formal  Charges, Valences, Oxidation States  Resonance Structures; Hyper and  Hypovalent sites   VSEPR

 Using the shapes of Molecules to  define:  Symmetry Operations  Symmetry Elements  Point Groups and Assignments

 Symmetry in Nature and in Molecules   Symmetry Operations  Symmetry Elements  Point Groups and Assignments

Symmetry elements/operations can be manipulated by  Group Theory, Representations and Character Tables

The following slides were modified from a gift from Professor Martyn Poliakoff Of the Department of Chemistry in Nottingham, England.  Tom Poliakoff also used these slides and prepared them, to my knowledge.  You might also check The MIT open courseware lecture to refresh your memory of molecular orbitals.

Solution will involve molecular orbitals - similar to atomic orbitals - but centred around all of the nuclei in molecule. Each defined by sets of quantum numbers,

Solids :  Four bonding classifications – Covalent bonding, which forms network covalent solids (sometimes  called simply "covalent solids” as in diamond and silicon dioxide) – Ionic bonding, which forms ionic solids * – Metallic bonding, which forms metallic solids* – Weak intermolecular bonding, which forms molecular solids*

What are the characteristics of the metals that might be correlated with their crystal structures? What is metallic Bonding? Can MO theory describe it? Account for properties?

In physical chemistry, the van der Waals force (or van der Waals' interaction), named after Dutch scientist Johannes Diderik van der Waals, is the sum of the attractive or repulsive forces between molecules (or between parts of the same molecule) other than those due to covalent bonds, or the electrostatic interaction of ions with one another, with neutral molecules, or with charged molecules.

Lewis, 1930s: Lewis Concept Base is a donor of an electron pair. Acid is an acceptor of an electron pair.

The defining characteristic of a RedOx reaction is that electron(s) have completely moved from one atom / molecule to another. The molecule receiving the electrons has been Reduced The molecule giving the electrons has been Oxidized

Labile or inert? Labile – a compound that undergoes reactions with a relatively high rate of substitution Inert – a compound that undergoes reactions with a slow rate of substitution Inert is a relative term, t 1/2> 1 min at 25 C
