Thomas Lewis Lab 243 Organic Chemistry Carol Higginbotham Environmentally Responsible Redox Chemistry: An Example of Convient Oxidation Methodology without Chromium Waste Reactants and Products The major reactants and products of this lab experiment are to describes how the oxidation of Benzoin to benzil, and also shows how the reduction of benzil to be generated to //meso//-hydrobenzoin. Major Concepts of this Experiment The major concepts of this experiment it to show the major concepts of electrons being gained and lost due to oxidation of a reactant and the reduction of a product. In this experiment benzoin is oxidized to benzil, not into benzoic acid. The benzil is then reduced into meso-hydrobenzoin and not into benzoin. These concepts help describe what is being oxidized from one product to be reduced to a lesser form of the original product. Theoretical and effective mass yield

Hazards Toluene, light petroleum, acetone, and ethanol are flamable and should not be used near naked flames or electrical sparks. They may ne harmful by inhalation, ingestion, or skin absortion and on contact may irritate the eyes or dry the skin. Magtrieve, Celite, benzil, and benzoin may all be harmful by inhalation, indegestion, or skin absortion and on contact may irritate the eyes and skin. The compounds may emit toxic fumes under fire conditions. Sodium Borohydride liberates a flammable gas when exposed to water. It is toxic in contact with the skin and if swallowed, and can cause burns. Ultra Violet lights may also burn the eyes.
