Course goals and philosophy Reinforce understanding of the basics of organic chemistry from Chemistry 201 and expand upon that with more detailed understanding of spectroscopy, multistep synthesis, concerted reactions of alkenes, reactions of aromatics and -carbonyl compounds. Additional techniques used in the synthesis, purification and analysis of organic compounds are emphasized in the laboratory with a focus on multistep synthesis and spectroscopy. Every reasonable methodology will be used to promote learning. Houseknecht Chemistry 302 Spring 2013 Assumed Skills To do well in Chem 302 you need to have some basic skills at your disposal. The following are many of the skills that you have encountered in Chem 201 and in general chemistry. I assume that you are proficient in the following: Structure VSEPR Reactivity Recognize acids and bases Mathematics Stoichiometry Valency and formal charge pKa Balancing reactions (including redox) Lewis dot structures Nucleophiles and electrophiles Calculation of percent yield Resonance Polarity Arrow formalism (curved arrows) Reaction kinetics and equilibria Hybridization and bond angles Representations of molecular structure Line-bond structures Stereochemistry Nomenclature of non-aromatics Students with disabilities Wittenberg University and I are committed to providing reasonable accommodations for eligible students with disabilities. If you are eligible for course accommodation due to a disability, please provide me with your self-identification letter from the Academic Services Office, 206 Recitation Hall, so that we may discuss your learning needs. Early identification at the start of the term is required to ensure timely provision of services. Grading criteria Final grades will be determined by performance on homework assignments, quizzes, hourly exams, the final exam, and laboratory assignments. The last day to drop without a “W” is Feb 8, 2011. Homework 15% Exams 50% Final exam 15% Laboratory 20% Grades will be assigned as detailed below. Scores within 2 – 3% of cut-offs will receive +/- modifiers as appropriate. I do reserve the right to assign letter grades more leniently. All course grades will be assigned based upon a class-wide scale, no individual exceptions will be granted. A 90 – 100% B 80 – 90% C 70 – 80% D 60 – 70% F 0 – 60% Homework Daily preparation is essential for success in organic chemistry. As such, homework problems will be assigned on a daily basis. Successful students will complete the problems assigned from the textbook prior to the ensuing class period. Homework will also be assigned for the online program OWL. To receive credit for each assigned exercise it must be completed by the due date. The website for OWL is http://owl.cengage.com/owl-c/user/loginpage.cgi?Server=owl-wittenbergunivmcmurry7e&UserType= Student. If you have any difficulty accessing or using this resource please ask for assistance immediately. Up to fifteen homework extra credit points will also be available by completing worksheets between the class in which they are distributed and the next class period. Houseknecht Chemistry 302 Spring 2013 Examinations Exams will be given during the normal class meeting time. All exams will be cumulative, although emphasis will be placed on material that has not yet been tested. Half the points on each exam will come from the assigned problems in the text or worksheets. Sample exams from previous years are available on the Q drive. Unexcused absence from an exam will result in a zero for that exam. Excused absences will be rescheduled. To receive an excused absence from an exam you MUST receive a written excuse from the instructor at least a day before the scheduled exam time or provide documentation of the unavoidable, unforeseen emergency. Re-grade requests must be discussed with the instructor within one week of the return of the exam. The final exam will be given on Friday, May 3rd at 8:00 am. The final exam will be the American Chemical Society (ACS) organic exam. Study guides for this exam are available through the ACS. The Chemistry Club will place an order for these in early February. Laboratory Laboratory is an essential component of this course. Therefore, you cannot pass Chem 302 if you do not achieve a passing grade in the laboratory. Laboratory grades will be based upon pre-lab quizzes, pre-lab exercises, post-lab reports, and performance in the laboratory. Organic chemistry lab is not dangerous (e.g., an abandoned mine field), but failure to prepare properly can result in serious injury. To avoid such unpleasantries, read the entire experiment (and any assigned reading) before coming to lab and always come to lab in appropriate lab attire (lab goggles, long sleeves, closed-toe shoes, etc.). Failure to do so can and will result in expulsion from that day’s lab and a zero on any related assignments. You are, of course, also expected to know the location of safety equipment and refrain from dangerous activities such as horseplay, eating, or drinking while in the laboratory.

There are certainly many reasons for this, but the primary reasons are: 1. It is a vast subject area that requires a substantial amount of material to be processed in the course of a semester. 2. It is one of very few subjects that is truly cumulative. A thorough understanding of the material covered at the beginning of the course is essential for success throughout the semester. Similarly, material covered later in the semester will further clarify material covered at the beginning of the semester. 3. It is a subject that many approach from an unproductive perspective. Prior to the Information Revolution, organic chemistry education consisted almost entirely of memorizing hundreds or thousands of reactions. This may have been appropriate for the time, but ready access to computers, the Internet, and powerful search engines, as well as advances in the field, have made rote memorization an essentially worthless endeavor. Most instructors of organic chemistry now emphasize the importance of understanding how and why a few essential organic reactions proceed. This approach makes the course grow easier as it proceeds and is the method we will use in Chem 201. Unfortunately, many students of organic chemistry have continued to emphasize memorization of as many reactions as possible. This usually becomes overwhelming by the midpoint of the semester. The resulting consternation of students who have worked very hard is predictable. So, what should a student of organic chemistry do to be successful? The short answer is to commit the necessary time to learning the material, particularly the first few weeks, and to focus upon understanding the processes of organic chemistry – not just the results. The long answer is to: 1. Always study material with the intent of understanding it. Another way to say this is to remember that the journey is more important than the destination, particularly when studying. 2. Study for 60 - 90 minutes a day, 4 - 6 days a week. This is much more efficient than waiting until a few days before the exam to begin studying. 3. Recopy your notes from lecture in a fresh notebook within 24 hours of lecture. 4. Complete the assigned homework problems within 48 hours. Waiting longer will leave you unprepared for the next class and overwhelmed by the shear number of problems to be worked. 5. Do as many practice problems as possible, not just the assigned homework problems. Consult other students, the instructor, or the solutions manual for every problem that you don't understand. 6. Avoid working problems with a solutions manual nearby. Using it to check your answers after you have answered a group of 5-10 questions can be valuable, more frequent use will negatively impact your understanding of the material and exam performance. If you are having trouble in the course and feel like you are drowning DO NOT reach for a solutions manual. Seek out help from classmates, the instructor, or the Chemistry Workshop (usually SMTTh evenings). 7. Study with several classmates on a regular basis. This time should be used to ask one another difficult questions and review key concepts, not to read the text or work on simple problems from the book. Finding a group of peers willing to prepare properly for group study should be a high priority the first few weeks of the semester. 8. Take the advice of students who have been successful in organic chemistry. I have compiled a list of suggestions and placed it on the Q drive.
