INSTRUCTOR: Prof. Mahdi Abu-Omar, 1515 Molecular Sciences Bldg., ext: 6-2602 OFFICE HOURS: T & W 9:00 – 10:00 am. Questions can also be sent via WWW to Virtual Office Hours (VOH) under the Chemistry Department Home Page or http://voh.chem.ucla.edu. TAs will arrange their own office hours. Students may attend the office hours of any TA and not just their own. TAs: Sylvia Daoud-Kinzie and Lee McPherson. TEXTBOOK: (Required) Principles of Modern Chemistry, 5th edition, by Oxtoby, Gillis, and Nachtrieb. (Optional) Study Guide for Principles of Modern Chemistry. READING & HW: You should read assigned chapters before lecture, and should do the suggested homework problems as a minimum. Homework problems will not be graded. Your TA will give occasional surprise quizzes during discussion; it is your responsibility to do the assigned homework in order to master the material. EXAMS: One 50-minute midterm exam is scheduled for Wednesday February 12 during the regular lecture time slot.
