• Resumen

  • A classroom demonstration involving the use of a bagel and cream cheese as an analogy for the two resonance contributors of benzene is described. This method emphasizes the deficiencies of using a single Lewis structure to describe the structure of benzene. Students are also reminded that benzene is a single entity and not a species that oscillates between two resonance contributors.
