1. What is the VSEPR theory and how can this predict molecular shapes? How do lone pairs of
electrons compare to bonding electrons?
2. What is polarity? How does one determine if a molecule will exhibit polar properties or not?
How does polarity of a molecule depend on the molecular geometry?
3. How does the valence bond theory compare to the Lewis theory? How are they different? How
are they similar? What are the benefits of one over the other?
4. What is hybridization? What does this tell us?
5. What are the two types of bonds? How are they different? How do the rotations observed in
each compare?
6. What is the equation for bond order and what does this tell you about a molecule?
7. Complete the following questions from your textbooks. Use the list to cross out your progress.
