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. On a piece of scrap paper, draw the resonance s...

T/F: Covalent bonds are present only when atomic orbitals interact constructively. Ans: True. Binding in Diamond Ans: Each carbon forms 4 bonds to 4 identical carbons; tetrahedral; sp3 Valence Bond Theory Ans: The idea that covalent bonds are formed when orbitals of different atoms overlap. T/F: Electrons are localized in molecular orbital. Ans: False T/F: Electrons are localized in Valence Bond. Ans: True T/F: When the hybrid orbitals combine, there is a large gap between the bondin...
