Chad gives a comprehensive lesson on Resonance, showing organic chemistry students exactly how to draw resonance structures easily. He starts by reviewing what students would have learned in General Chemistry including the idea that resonance implies delocalized electrons which typically results in greater stability. He then covers numerous resonance structure examples relevant to organic chemistry including resonance with carbocations, resonance with lone pairs of electrons, resonance with radicals, and how to draw resonance structures with arrows. He also shows how to predict what the structure of the resonance hybrid should look like and how to determine which resonance structures are major or minor contributors. Finally, Chad shows the relationship between resonance and hybridization, and how to properly determine the hybridization of an atom when resonance is a factor.

Answer each question based on the video lesson on resonance. No outside knowledge is required — all answers can be found in the video.
Apply the arrow-pushing rules and resonance principles from the video to draw structures, identify contributors, and determine hybridization. Show all work and reasoning; problems increase in difficulty.
These are challenging, exam-level questions that push beyond the basics of resonance — expect multi-step reasoning, structure evaluation, and real-world applications. Work carefully through each scenario before answering.
