Abstract
In this analogy, puppy dogs are restricted to a specific dog run; they represent s-bond electron pairs. Big dogs are allowed to roam freely over several consecutive dog runs; they represent delocalized p-bond electron pairs. By adding a bunny rabbit who is chased by the big dog, the analogy can be expanded to account for delocalized formal charge in a resonance hybrid.

Assessment of Organic Chemistry Students’ Knowledge of Resonance-Related Structures
Rosa Betancourt-Pérez and Luis Javier Olivera, Julio E. RodríguezJournal of Chemical Education2010 87 (5), 547-551Assessment of Organic Chemistry Students’ Knowledge of Resonance-Related Structures
Rosa Betancourt-Pérez and Luis Javier Olivera, Julio E. RodríguezJournal of Chemical Education2010 87 (5), 547-551This study examines how well second-year nonmajor organic chemistry students are learning to draw, interpret, and understand resonance-related structures. Students were tested seven times throughout an academic year using a set of four tasks that ...
Acid-Catalyzed Enolization of β-Tetralone

Brahmadeo Dewprashad , Anthony Nesturi and Joel UrenaJournal of Chemical Education2008 85 (6), 829This experiment allows students to use 1H NMR to directly compare the relative initial rates of substitution of the benzylic and non-benzylic α hydrogens of β-tetralone and correlate their findings with the predictions made by resonance theory. The ...
Aromatic Bagels: An Edible Resonance Analogy
Shirley LinJournal of Chemical Education2007 84 (5), 779Aromatic Bagels: An Edible Resonance Analogy
Shirley LinJournal of Chemical Education2007 84 (5), 779A 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 ...
If It's Resonance, What Is Resonating?
Robert C. KerberJournal of Chemical Education2006 83 (2), 223If It's Resonance, What Is Resonating?
Robert C. KerberJournal of Chemical Education2006 83 (2), 223The resonance terminology that accompanies use of more than one Lewis-type structure to describe delocalized bonding in molecules has been leading students astray for more than half a century. In this article I review the origin of the terminology and how ...

Trevor M. KitsonJournal of Chemical Education2001 78 (4), 504Intermediates, Transition States, Butterflies, and Frogs
Trevor M. KitsonJournal of Chemical Education2001 78 (4), 504An analogy that may be useful in the classroom is described. The changes that occur in typical simple SN1 and SN2 reactions are compared to the metamorphoses undergone by caterpillars and tadpoles, respectively.
