How do you determine resonance structures?

Using Formal Charges to Identify viable Resonance Structures

  • The greater the number of covalent bonds, the greater the stability since more atoms will have complete octets.
  • The structure with the least number of formal charges is more stable.
  • The structure with the least separation of formal charge is more stable.

    • How do you draw resonance structures with formal charges?

    Be sure to draw curved arrows showing the movement of electrons and include any relevant reagents, conditions, or resonance structures needed for the reaction. There is much that can be done with ChemDraw but you now know the basics. Play around with the different tools to become familiar with them.
