446 - Resonance structures: What they are and what they aren't

Carmen J. Giunta Department of Chemistry & Physics, Le Moyne College, Syracuse, NY, United States

The concept of resonance structure is a perennial source of confusion and misconception in introductory chemistry courses. At least three distinct sources of confusion can be identified: the association of the term resonance with oscillatory phenomena, the similarity of the resonance arrow to reaction and equilibrium arrows, and the ontological status of the idealized components of a resonance hybrid. Examination of the history of resonance structures reveals that similar confusion attended the concept from its inception.
