Modular exercises were developed at Diablo Valley College for each of the two courses in the respective 2-semester sequences in lower division General Chemistry and Organic Chemistry: (Greenhouse Gas Molecules, Global Climate Change, VSEPR, Transition metal complexes, Introduction to organic molecular shapes, symmetry and chirality, molecular structures in olfaction/ chemical communication, and the Diels Alder reaction).
Sophie was a workshop leader in the early developmental days of Workshop Chemistry. (The authors wish to express their gratitude to Sophie for her insight and contributions to this unit.) This method relates the number of electrons transferred to change in oxidation number. For reduction half-reactions, add the electrons to the left side of the equation; for oxidation half-reactions, add the electrons to the right side of the equation.
