Resonance Structures | 2.4 Organic Chemistry
After this lesson you will be able to…
- Understand delocalized electrons, resonance structures, and the resonance hybrid.
- Learn the rules for moving non-bonding and pi electrons in resonance structures.
- Draw resonance structures to stabilize carbocations using adjacent pi electrons.
- Draw resonance structures for lone pairs using a two-arrow pushing pattern.
- Use half-headed arrows to draw resonance structures for radicals.
- Determine which resonance structure is the most stable major contributor.
- Practice drawing resonance structures for molecules with heteroatoms.

Quiz: Resonance Structures and Electron Delocalization
FundamentalsAnswer each question based on the video lesson on resonance. No outside knowledge is required — all answers can be found in the video.
Practice: Resonance Structures and Arrow-Pushing
PracticeApply 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.
Advanced: Resonance, Electron Delocalization, and Stability
AdvancedThese 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.
