Formal Charge and Resonance
Formal charge helps determine the most stable Lewis structure, while resonance describes delocalization of electrons across multiple valid structures.
Why this shows up in the exam
You may be asked to calculate formal charges, identify resonance structures, and predict their effects on molecular properties.
