Diels-Alder Visualization Several computer animations of a Diels-Alder reaction that were created as an undergraduate student project are presented.
Addition Reactions |
Alkenes
Addition Reactions of Alkenes The Diels-Alder reaction, addition of oxygen to tetrakis(N, N-dimethylamino) ethylene, polymerization of ethylene, and addition of iodine to a-pinene are demonstrated. Molecular models of ethene are shown.
Acid-Catalyzed Enolization of β-TetraloneBrahmadeo Dewprashad, Anthony Nesturi, and Joel Urena This experiment allows students to use 1H NMR to compare the rates of substitution of benzylic and non-benzylic a hydrogens of -tetralone and correlate their findings with predictions made by resonance theory. Dewprashad, Brahmadeo; Nesturi, Anthony; Urena, Joel. J. Chem. Educ.2008, 85, 829.
"You're Repulsive!"Teaching VSEPR in a Not-So-Elegant WayRobert S. H. Liu 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 Youre Repulsive! is the common thread used throughout these five examples. Liu, Robert S. H. J. Chem. Educ.2005, 82, 558.
