Question 1.
What are resonance structures?
Show hintHide hint
Look for structures that differ only in electron placement.
Question 2.
Give an example of a molecule that exhibits resonance.
Show hintHide hint
Think of a molecule with alternating double bonds.
3Question 3.
What is a resonance hybrid?
- A single structure
- An average of multiple structures
- A temporary state
Show hintHide hint
Think about what averages do in mathematics.
4Question 4.
True or False: Resonance structures can differ by the positions of the atoms.
- True
- False
Show hintHide hint
Consider how the definition of resonance limits atom movement.
Question 5.
Draw and compare the resonance structures of acetate ion (CH3COO–) and nitromethane (CH3NO2). Discuss their stabilities.
Show hintHide hint
Draw all reasonable structures and evaluate their stability based on previous rules of resonance.
Question 6.
For the compound benzene, analyze the implications of resonance on its reactivity in electrophilic substitutions.
Show hintHide hint
Think about how stable the starting and transition states are during reactions.
