Summary
Abstract: This paper addresses the development and evaluation of a case study designed to introduce both the core chemistry concepts of oxidation and reduction reactions as well as green chemistry within the undergraduate organic chemistry curriculum. The developed case study consisted of two parts that can be used in tandem or independently. Part 1 focused on calculating oxidation states and determining whether the provided bioderived reactions represented oxidation or reduction reactions, and Part 2 focused on evaluating the greenness of oxidation reactions. Students reported positive learning gains for both the core chemistry concepts of oxidation and reduction reactions and green chemistry and reported that they viewed the case study favorably. It is our hope that other educators use this case study module to incorporate green chemistry into their organic courses and use its development as inspiration to create further case studies that integrate green chemistry into the curriculum.

Learning Goals/Student Objectives
Part 1
Skills. After doing this assignment you should be able to:
1. Classify organic reactions as oxidation, reduction, or neither.
2. Identify reagents used for oxidation and reduction reactions.
Knowledge. After doing this assignment you should understand:
1. How oxidation states change in oxidation and reduction.
2. That oxidation and reduction refer to the overall change in oxidation states of the atoms of
the molecule, not just individual atoms.

Part 2
Skills. After doing this assignment you should be able to:
1. Locate and read Safety Data Sheets for chemicals.
2. Compare oxidation reagents for safety and environmental hazards.
3. Compare solvents for safety and environmental hazards.
4. Evaluate organic reactions using the green chemistry principles.
Knowledge. After doing this assignment you should understand:
1. How solvents and chemicals differ in their safety and environmental impacts.
2. How a variety of factors are considered when evaluating the greenness of a reaction.
Common pedagogies covered
Problem-based learning
Time required (if applicable)
2 class periods, or can be assigned as homework
