1. Write the "best" Lewis structure (minimize formal charge, maximize number of resona structures) for the following species. Include formal charges on all atoms having any and give resonance structures. When appropriate, expand the octet to reduce formal charges and gain resonance structures. Give the electronic and molecular geometries for each and determine i they are polar or nonpolar. NO2 SO32- PO43- 2. Use formal charge to determine which Lewis structure is better: H-5--H H- -3-H

Day 11-14: Draw the most stable Lewis structure possible for each molecule, and give as much information as you can. Place any formal charge on the correct atom(s). Label the structure if it involves resonance. Describe the molecular geometry about EACH of the central atoms, and if the molecule is polar, represent the overall dipole of each molecule. Describe each of the intermolecular forces present in a pure sample of compound you drew a Lewis Structure for.
