Oxidation / Reduction
Induction by Iron(II) of the Oxidation of Iodide by Dichromate Acidic aqueous solutions containing dichromate and iodide ions are mixed with no reaction. The addition of a solution of iron(II) ion induces the rapid formation of brown triiodide ion.

Chirality A series of chiral and achiral objects, the interaction of polarized light with organic molecules, the assignment of R- and S- configuration, Fisher projections, and a stereospecific reaction are demonstrated.
Synthesis Explorer: A Chemical Reaction Tutorial System for Organic Synthesis Design and Mechanism PredictionJonathan H. Chen and Pierre Baldi Synthesis Explorer is an interactive tutorial system for organic chemistry that enables students to learn chemical reactions in ways previously unrealized. Pedagogical experiments in undergraduate classes at UC Irvine indicate that the system can improve average student examination performance by ~10%. Chen, Jonathan H.; Baldi, Pierre. J. Chem. Educ.2008, 85, 1699.

The Aromaticity of Pericyclic Reaction Transition StatesHenry S. Rzepa Presents an approach that combines two fundamental concepts in organic chemistry, chirality and aromaticity, into a simple rule for stating selection rules for pericyclic reactions in terms of achiral Hckel-aromatic and chiral Mbius-aromatic transition states. Rzepa, Henry S. J. Chem. Educ.2007, 84, 1535.
