What will I learn?
This course teaches a quick, hands-on method for drawing precise Lewis structures, calculating formal charges, and assessing resonance forms. You'll work with examples like CO2, NO3-, SO2, ClF3, and NH3, link 2D diagrams to 3D geometries via VSEPR theory, manage ions and odd cases, dodge typical pitfalls, and end with a solid checklist for flawless, pro-level diagrams every time.
