CHEM 4731/5731 Name: ______________________ Problem Set #1: Oxidation of carbon, photosynthesis Due in class Thursday, January 20, 2011 1a. Draw glycine and indicate the formal oxidation number of each carbon. . 1b. Rank the following molecules in order of oxidation state of their carbon atom with the most oxidized at the bottom and the most reduced at the top. methanol, carbon dioxide, methane, formaldehyde Most reduced: Most oxidized: 2. For the production of one molecule of oxygen during the light reactions of photosynthesis (utilizing non-cyclic electron transport) answer each of the following questions. Each answer is worth half of a point. a. What is the minimum number of 680 nm photons needed?
