1) Define " reaction mechanism." In responding to this, and subsequent, discussion topics, I will primarily be drawing from material discussed in Organic Chemistry – 6 th Edition , authored by Fessenden and Fessenden. Although I think our textbook is one of the better textbooks for explaining the material pertinent to this course, it is my hope that this text will provide additional insight not otherwise addressed by Organic Chemistry with Biological Applications . According to Fessenden and Fessenden, reaction mechanisms are defined as “the detailed description of how a reaction occurs.” In this manner, reaction mechanisms take into account “all known facts.” Fessenden and Fessenden also note that for some reactions, there are a considerable number of known facts and are accepted by most chemists. Whereas for others, the mechanisms are still “speculative.” The amount of known facts are supported by experimental data. I actually think that the definition of reaction mechanism provided by

Unformatted text preview: Fessenden and Fessenden is insufficient. So for the sake of being thorough, I’ll just recap what is discussed in our course textbook. As mentioned previously, reaction mechanisms provide detailed descriptions of how a reaction occurs (e.g., addition, elimination, substitution, rearrangement). But more specifically, reaction mechanisms describe what takes place at each stage of chemical processes through indicating the intermediates, if any, formed. Despite their high energy states and our inability to isolate these molecules in lab settings, some mechanisms may propose transition states of some chemical reactions. Furthermore, reaction mechanisms may also describe which bonds are broken or formed and in what order. They may also provide information on the relative rates of the reaction and experimental conditions (e.g., temperature). Overall, complete mechanisms will account for all reactants used (including catalysts), and all products formed....
