Each section will apply fundamental concepts to important examples such as the environment, alternative fuels, batteries, H-fuel cells, organic and biological molecules, and biophysical applications. Material covered will also be related to your 14BL lab experiments, in particular your experiments with p-nitrophenylacetate and aspirin. LECTURES: M, W, F 10am in CS24. INSTRUCTOR: Dr. Laurence Lavelle, 3048A Young Hall. OFFICE HOURS: M, W, F 1 – 2pm. Brief questions will also be answered after each lecture. Course related information will be available, and your questions can be posted, at any time to the Virtual Office Hours (VOH) under the Chemistry & Biochemistry Department Home Page (http://voh.chem.ucla.edu). All technical problems with VOH must be sent to: [email protected] TA's (Teaching Assistants): Sanaz Kabehie [email protected], Cesar Mejia [email protected], and Jennifer Robbins-Luft [email protected]. TA's will arrange their own office hours and these will be posted on VOH. You may go to any TA office hour. REQUIRED TEXTS: Chemical Principles: The Quest for Insight, 3rd edition, by Peter Atkins & Loretta Jones (with solution manual & model building kit); and Organic Chemistry, 4th edition, by Paula Bruice (with study guide & solution manual). Careful consideration went into choosing these texts, you will find them good to read. Note: Several other chemistry textbooks have been placed on reserve in College Library, if you desire further supplementary material. READING & HOMEWORK: Read assigned chapters before the related lectures occur. Working through problems will facilitate your learning the course material and developing your problem solving skills. Homework problems are given with the lecture schedule on the back of this page. Homework is not turned in or graded. It is your responsibility to do (at least) the assigned homework in order to master the material covered. You should plan for eight hours of independent study per week, and the more problems you do, the more you will learn. ORGANIC SOFTWARE & MODELING ASSIGNMENTS: ChemDraw and Chem3D are very useful in learning to draw, visualize and analyze molecules and are the most commonly use software packages used by chemists at universities and in industry. You will be using this free software in our excellent Science Learning Center (SLC). EXAMINATIONS: Two 45 minute quizzes will be given in discussion sections. See VOH for schedule. The midterm exam is Wednesday, May 10, 6 to 8pm. The final exam is Tuesday, June 13, 3 to 6pm. Special Bonus: The each exam will include one question that will be taken from your Student's Solutions Manual. So it is very much in your interest to work through these questions.All quizzes and exams must be written in pen. No make-up quizzes or exams will be given. No one will be permitted to take the final exam either earlier or later than the scheduled time, and no one can receive a passing grade for the course without taking the final exam. There are no regrades. Only non-programmable, non-graphing calculators will be allowed during exams. Pagers and cellular phones are not allowed in the classroom during lectures or exams. Students possessing such items during exams or who commit other forms of academic dishonesty will receive a zero on the exam and will be referred to the Dean of Students. GRADING: Quizzes 25% (50pt x 2 = 100pt) (45min x 2 = 90min) Midterm 30% (120pt) (110min) Final 45% (180pt) (170min) Total 100% (400pt) All quizzes and exams have a total score but grades are only assigned at the end of the course. At the end of the quarter when the class average score (out of 400 points) is known are individual and final grades assigned and they are based/curved on the class average. However you need 50% or higher (200 points or higher) to pass this course with a C- or higher.
