"You're Repulsive!"—Teaching VSEPR in a Not-So-Elegant Way

Valence shell electron pair repulsive (VSEPR) interaction is an important concept particularly in discussing structural properties of molecules. In this article we showed five organic examples not commonly associated with VSEPR but yet all involving repulsive interactions of valence electrons, which...

Description
Summary:Valence shell electron pair repulsive (VSEPR) interaction is an important concept particularly in discussing structural properties of molecules. In this article we showed five organic examples not commonly associated with VSEPR but yet all involving repulsive interactions of valence electrons, which provides ready explanations for altered chemical reactivity and spectroscopic properties of organic compounds. The ready catchy phrase “You’re Repulsive!†is the common thread used throughout these five examples. It could be a substitute for the difficult-to-remember acronym, VSEPR, for the concept.
