4.4 Extra Problems
16. For the following structures, if possible, push the lone pair electrons to generate other good, valid resonance structure(s). If no other good resonance structures can be drawn, say “no resonance structures.”
17. Which of the following is NOT a viable resonance structure of the others?
18. The following intermediate has four atoms that have a partial negative charge. Use resonance forms to identify these four negative atoms.
19. For each pair of ions, identify the one that is more stable because the charge can be spread out through resonance forms.
20. The following resonance structures have an error in them. Either the arrow(s) are incorrect, or the resonance structure drawn is incorrect. Correct the errors.
21. Draw all good, valid resonance forms of the following intermediates.
