Rule #1: Resonance structures must have the same number of electrons. (you should prove it to yourself by counting them). | |
Rule #2: All resonance structures must be valid Lewis dot structures. | |
Rule #3: The hybridization does not change between resonance structures. | |
Rule #4: The positions of atoms are the same in all structures. | |
Rule #5: Resonance structures do not have to be equivalent. |
