CHEM 219 EXAM 1 QUESTIONS WITH ALL CORRECT ANSWERS 
Describe how individual resonance structures impact the true structure of a molecule or polyatomic ion. - Answer Each contributing individual resonance structure contributes characteristics to the overall hybrid structure of the compound. The hybrid "averages" bond lengths and formal charges by delocalizing them among atoms that share them in each contributing individual resonance structure.
