Each section will apply fundamental concepts to examples from inorganic and organic chemistry, including reactions that impact the environment. LECTURES: See online schedule. You may attend only the lecture you are enrolled in. INSTRUCTOR: Dr. Laurence Lavelle, 3048A Young Hall, Chemistry & Biochemistry OFFICE HOURS: W & F 4-5pm. 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 Virtual Office Hours (VOH) at http://voh.chem.ucla.edu. All technical problems with VOH must be sent to: [email protected] TAs (Teaching Assistants): To be announced. You may attend only the discussion section you are enrolled in. TA's will arrange their own office hours and these will be posted on VOH. You may go to any and all TA office hours. Chem 14B is unique: In class lectures (Yes) Podcast lectures (Yes) Webcast lectures (Yes) Discussion sections (Yes) Online materials (Yes) And ... Including Dr. Lavelle's office hours and all TAs - a total of 27 office hours every week! In addition to Virtual Office Hours 24/7 for 11 weeks of the 10 week quarter! In addition to over 30 hours of midterm and final exam review sessions! TEXTBOOK: Same as Chem 14A; Chemical Principles The Quest for Insight, 5th Ed., by Peter Atkins & Loretta Jones. The textbook, solutions manual, study guide, and model building kit are available as one bundled package at the UCLA bookstore. The model building kit is used in Chem 14B/C/D. If you desire further supplementary material several other chemistry textbooks have been placed on reserve in College Library. COURSE READER: The Chem 14B course reader and workbook includes all course related material, all lecture notes with additional background material, past exams with solutions, and additional quizzes to work through. The text and equations are typeset to allow the student sufficient space to write additional class notes. With this course reader the student should not need any additional notepaper for taking class notes. It is available only at Course Reader Material, 1081 Broxton Ave, Westwood (two blocks south of campus). Chem 14B Dr. Laurence LavelleREADING & HOMEWORK: Read the assigned chapters. Working through the assigned problems will facilitate your learning the course material and will also develop your problem solving skills. 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. Do at least 8 hours of independent study per week, and the more problems you do, the more you will learn. ORGANIC SOFTWARE & MODELING ASSIGNMENT: 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 software in our computer rooms on the 4th floor of Young Hall. The organic worksheet assignment in your Workbook is due on or before Friday of Week 9 in class. QUIZZES & EXAMINATIONS: Two 40min quizzes in discussion section. One 2hr midterm exam. One 3hr final exam. All material is directly related to class notes and the readings and homework problems in the textbook, course reader, and workbook. The best preparation for all of these is to be able to independently work through the assigned homework problems. See VOH for quiz and exam schedule. The Preparatory Self-Quizzes in your Workbook will also be helpful. The Preparatory Self-Quizzes must be handed in to your TA. All uncollected work is kept by your TA until the end of the quarter, after the final exam it is recycled. To 'encourage' students to do the assigned homework problems both the midterm and final will include one homework question. All exams must be written in pen. No make-up 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 are allowed. Pagers and 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 (2 x 40 mins) 80 pts Organic Worksheet Assignment 40 pts One 2hr Midterm (110 mins) 110 pts One 3hr Final (170 mins) 170 pts Total 400 pts Each quiz, worksheet, midterm and final has a total score but is not assigned a grade. Only 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.
