Applications and Analogies
Aromatic Bagels: An Edible Resonance Analogy
Shirley Lin
Department of Chemistry , United States Naval Academy, Annapolis, MD 21402
Cover
May 2007
Vol. 84 No. 5
p. 779
Abstract
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.
