<center>Bonding <nowiki>II and Intermolecular Force (IMF)</nowiki></center> 
 
Essential Question: Do you believe that? (theory explains observations)

Each student will be able to:

1. Using the knowledge from Lewis Dot Structures <nowiki>VSEPR (Valence Shell Electron Pair Repulsion)</nowiki>, predict the geometry and bond angle of simple molecules and polyatomic ions. [http://www.doe.mass.edu/frameworks/scitech/2001/standards/chem10_114.html 4.4](4.4)

2. Understand and explain Hybrization as the theoretical basis of <nowiki>VSEPR</nowiki> and how to determine the hybrization (sp, sp2,etc) on a central atom given the Lewis Dot Structure.[http://www.doe.mass.edu/frameworks/scitech/2001/standards/chem10_114.html 4.4]

3. Determine the Bond Polarity (<nowiki>BP</nowiki>) between two atoms using the knowledge of each atom's electronegativity (<nowiki>EN</nowiki>). (4.3)

4. Using <nowiki>BP</nowiki> and the molecular geometry, determine (explain) the Molecular Polarity (<nowiki>MP</nowiki>) of a species. Be able to explain the similarities and difference between polar (dipole) molecules and non-polar molecules. 
 
5. Identify the 4 types of intermolecular forces (London Dispersion Forces <nowiki>(LDF)</nowiki>, Dipole - Dipole, Hydogen bonding, Ionic bond and Metallic bond) present based on molecular geometry and polarity (either bond or molecular). For <nowiki>LDF</nowiki>, dipole - dipole and Hydrogen bonding, the student needs to know and understand what causes each type of <nowiki>IMF</nowiki> to have higher or lower force within each of these groups.relative strength of these substance for each what causes molecules to have varying degrees of strength for [http://www.doe.mass.edu/frameworks/scitech/2001/standards/chem10_114.html 4.5]

Updated 2006 - (4.5)Identify how hydrogen bonding in water affects a variety of physical,chemical,and biological phenomena (such as surface tension, capillary action, density, and poiling point).
