  • Student Learning Outcomes:

    Upon completion of this lesson, you will be able to:
    • Compute formal charges for atoms in any Lewis structure.
    • Use formal charges to identify the most reasonable Lewis structure for a given molecule.
    • Explain the concept of resonance and draw Lewis structures representing resonance forms for a given molecule.
    • Define formal charge and describe the rules for obtaining formal charge.
    • State two rules useful in writing Lewis formulas.
