The course provides a foundation for further work in organic chemistry (Chemistry 22/24) and biochemistry (Chemistry 31). Chemistry 21 encompasses both modern organic chemical theory and the descriptive chemistry of the principal functional groups. Topics include bonding and structure, nomenclature, stereochemistry, structure-reactivity relationships, and synthesis and reactions of the hydrocarbons and derivatives. Emphasis is placed on application and interpretation of experimental data in determination of molecular structure and in elucidation of reaction mechanisms, and on development of practical strategies for synthetic interconversion among functional groups. The laboratory work focuses on techniques of synthesis, isolation, purification and analysis, both in theory and in practice. 1) Textbook: David Klein, Organic Chemistry, 2nd Edition.

GRADING POLICY Exams There will be 4 exams @ 120 points. The exams will cover the textbook, the lectures, and the laboratory sessions. No make-ups will be permitted. One exam score will be dropped at the end of the course. If an exam is missed, for any reason, that exam will be the one dropped. If all exams are taken, the lowest score will be dropped. Homework Organic chemistry is not a spectator sport. You cannot learn organic chemistry by passively reading the textbook and listening to the instructor. You learn organic chemistry by becoming actively involved in it and doing it. One of the most important aspects of active participation in the learning process is problem solving. For each chapter of the text there are assigned problems. You should, at a minimum, work these problems. Complete worked-out solutions are provided in the Study Guide & Solutions Manual. Do not merely look at these worked-out solutions; make a serious effort to work the problems on your own. The solutions should only be used to check yourself after you have finished a problem or to seek help in getting started if you become totally frustrated with a problem. Homework will not be collected or graded. However, the level of learning and corresponding success in the course are related to the time and effort spent in problem solving. Laboratory Experiments Laboratory experience is one of the most important components of an organic chemistry course. Almost all aspects of organic laboratory work, from experimental theory and technique to notebook keeping and report writing, are new to most students and different from most laboratory experience in general chemistry. A total of 7 experiments @ 15 points will be performed. Make-ups will not be possible. One lab score will be dropped at the end of the course. If a lab is missed, for any reason, that lab will be the one dropped. If all labs are completed, the lowest score will be dropped. Full details of the laboratory work will be presented in separate handouts distributed at the laboratory orientation session. Final Exam The final exam, worth 150 points, will be comprehensive in nature and is mandatory.
Summary 3 of 4 exams @ 120 points = 360 points 6 of 7 lab experiments @ 15 points = 90 points final exam @ 150 points = 150 points Total = 600 points Grading Scale Table Percent of Course Grade Point Range Total Points Possible A 540-600 90.0-100 B 468-539 78.0-89.9 C 390-467 65.0-77.9 D 300-389 50.0-64.9 F < 300 < 50.0 The table above shows the minimum guaranteed grade ranges. At the end of the course some slight downward curving of these ranges is possible, if appropriate - - but don't count on it. ADDITIONAL COURSE REQUIREMENTS Attendance Successful completion of this course requires full participation in all class activities, including lecture sessions and laboratory periods. Regular daily attendance in lecture and laboratory is both expected and required, especially during an intense six week summer session. Excessive absences may result in being dropped from the course. Punctuality is also important -- plan to arrive in class on time. Remember to allow for parking problems, etc. Students who arrive late not only miss important material, but also disrupt the class. Withdrawal Be aware of college regulations and deadlines regarding dropping classes: for tuition refund, to avoid a W on transcript, and for a guaranteed W. See your Corsair Connect account for specific dates. If you want to drop the course, it is your responsibility to drop yourself online, otherwise you could inadvertently end up with an "F" on your transcript. Code of Academic Conduct The Academic Honor Code of Santa Monica College will be strictly enforced in this course, and academic dishonesty in any form will not be tolerated. This includes, but is not limited to, cheating on exams, changing answers on graded assignments, copying of lab reports, and falsification of lab data.
SOME ADVICE ON SUCCESS IN THIS COURSE 1,2 Organic chemistry opens a whole new world of chemical knowledge and represents a new way of thinking about chemistry. The study of organic chemistry involves not only learning a seemingly endless amount of information, but also processing that information in an efficient manner. Most beginning students find organic chemistry to be challenging, and many find it to be quite difficult, at least initially. Even students who have done well in general chemistry, where the approach is largely mathematical, sometimes find themselves struggling in organic chemistry, where the approach in primarily conceptual. Organic chemistry is a highly organized and very precise discipline. It involves sorting facts, analyzing problems, looking for patterns and reasoning by analogy. Learning organic chemistry is like learning a new language. The key to success in organic chemistry is not much different from any other chemistry course: active participation in the learning process, consistent daily effort, keeping up rather than catching up, and maintaining a positive attitude. Success involves hard work, for which there are no shortcuts. Organic chemistry is an intense, demanding and challenging course under any circumstances, but especially in a six-week summer session. This is a 5 unit course for which you will spend 25 hours per week in class. You should expect to spend at least that much time per week on your own outside of class if you want to complete the course successfully, with a good grade and a strong base of knowledge and skills needed for continuing in chemistry or other science courses. The most important advice to remember (and follow) in studying organic chemistry is DO NOT FALL BEHIND! The individual steps to learning organic chemistry are quite simple; each by itself is relatively easy to master - but they are numerous, and the subject can quickly become overwhelming if you do not keep up. Before many of the theories and mechanisms were figured out, organic chemistry was a discipline that could be mastered only through memorization. Fortunately, that is no longer true. You will find many unifying ideas that allow you to use what you have learned in one situation to predict what will happen in other situations. So, as you read the book and study your notes, always making sure that you understand why each chemical event or behavior happens. When the reasons behind reactivity are understood, most reactions can be predicted. Approaching the course with the misconception that to succeed you must memorize hundreds of unrelated reactions could be your downfall. There is simply too much material to memorize. Understanding and reasoning, not memorization, provide the necessary foundation on which to lay subsequent learning. Nevertheless, from time to time some memorization will be required: some fundamental rules will have to be memorized, and you will need to learn the common names of a number of organic compounds. The scientific discipline of organic chemistry is NOT merely a compilation of principles, but rather, it is a disciplined method of thought and analysis. Students must certainly understand the concepts and principles, but more importantly, students must learn to think like organic chemists... that is, they must learn to become proficient at approaching new situations methodically, based on a repertoire of skills. That is the true essence of organic chemistry. Students who study organic chemistry to gain entrance into medical school sometimes wonder why medical schools pay so much attention to this topic. The importance of organic chemistry is not in the subject matter alone. Mastering organic chemistry requires a thorough understanding of certain fundamental principles and the ability to use those fundamentals to analyze, classify, and predict. The study of medicine makes similar demands: a physician uses an understanding of certain fundamental principles to analyze, classify, and diagnose. Read the appropriate sections of each chapter before you come to the lecture on those sections. Take good comprehensive notes during lecture. Then, as soon as possible after each lecture, re-read the same sections in the text, along with the notes you took. Have pencil in hand to work on the problems relating to those topics. As you go along, make a list of your questions to bring to class or to submit on ecompanion. 1 Taken in part from Klein, Organic Chemistry, 2nd Edition. 2 Taken in part from Bruice, Organic Chemistry, 7th Edition.

CHEM 21 STUDENT LEARNING OUTCOMES (SLOs) 1. The student will follow a logical process based on well-established scientific principles and demonstrate the ability to use the appropriate problem-solving techniques to solve a scientific problem such as an organic synthesis comprised of two or more steps, or a determination of the structure of a compound based on spectroscopy (IR, NMR, MS) and/or chemical evidence. 2. When conducting a laboratory experiment, the student will follow written procedures commonly used in the organic lab (such as reflux, distillation, extraction, recrystallization, and melting point determination) accurately and safely. When completing a lab report, the student will apply the scientific method correctly by being able to state a hypothesis, take careful measurements, estimate uncertainties and draw appropriate conclusions based on gathered data and scientific principles. 3. The student will explain observable phenomena using appropriate scientific theories, such as writing a reaction mechanism consistent with observed facts or utilizing appropriate structures to represent different types of organic molecules and species.
