Depending on the extent of your academic preparation and recent college-level coursework in this topic area, the amount of study time needed may vary considerably. Course Description: This laboratory class covers the synthesis and analysis of compounds; purification by extraction, chromatography, recrystallization, and sublimation; characterization by mass spectroscopy, UV, NMR, and IR spectroscopy, optical activity, electrochemistry, pH titration. Prerequisite: Chemistry XL 14B, 14BL, and 14C, with grades of C- or better. Enrollment limited. Visitors not permitted. Textbooks and supplies: Techniques in Organic Chemistry Third Edition, J. R. Mohrig, C.N. Hammond, P.F. Schatz, W. H. Freeman (ISBN-13: 978-1-4292-1956-3; ISBN-10: 1-4292-1956-4) (Text = T); Chemistry Experiments for Life Science Majors, Second Edition, A. A. Russell, Burgess Publishing Company (ISBN = 0-8087-2517-3)(Manual = M). In addition, for the lab you will need a laboratory notebook. “Composition Books” with sewn-in pages are not acceptable. Laboratory notebooks are required to have sequentially numbered pages that create duplicate copies. One copy of each numbered page will be submitted to the instructor and the corresponding duplicate page will remain in the students’ notebook. Furthermore an approved lab coat and approved splash-protective safety goggles are required. Web Enhanced Course: This course will use a password-protected internet site on Blackboard to post course materials and announcements. Course materials can include the syllabus, handouts and internet links referenced in class (no hard copies of course materials will be made available in class; please print any reference materials you would like to have in class). Here are some important points about web-enhanced courses: • Students must have basic computer skills, including the use of word processing, email and the ability to use internet browsers such as Internet Explorer or Netscape. Completion of the Blackboard Student Orientation is recommended. • Course materials will become available two days before the beginning date of the course. Lab Preparation and Pre-lab Reports: You must be prepared for the experiment before you come to lab in order to complete the experiment in the time allotted. The course is impacted; there is neither make-up time in the course nor space for you to work in other sections. If you miss a lab, you MUST discuss the issue with the course instructor to see what other options you may have to complete the experiment. You are expected to do your lab work in your scheduled period; your grade will be 2 affected by not completing lab work in a timely manner. In preparation for the lab you should first study the pertinent sections in the text, review the lecture notes pertaining to the experiment, then view (and possibly review) the appropriate videos for any new techniques to be used in the experiment. Following the instructions in the report guidelines posted on the course website, complete any assigned pre-lab study questions in your lab notebook. Then write the assignment introduction, procedure (including a reference to the original source and a flowchart summary of the experimental steps), and set up the data tables for the experiment in your notebook before the lab section meets. This preliminary work is due during the first fifteen minutes of your lab period. No credit for pre-lab work will be given after this time. Any student who has not completed the preliminary work, will be required to complete the preparation before commencing lab work. During lab, you will complete the data tables and record any other observations about the experiment. The duplicate copy of this in-lab work must be turned in to the TA at the end of the lab period if you are to receive credit for the assignment. Post-lab Reports: The remainder of the lab report—the data analysis, error analysis, and conclusions —are to be completed in the lab notebook after the experiment is finished. The original copy of this portion of the report along with any graphs and spreadsheets is turned in to the TA at the start of the following lab period. Unexcused late post-lab portions of the reports will accrue a penalty of five percent of the grade per day. No reports will be accepted more than two weeks after the due date or after 5:00 p.m. on the last day of instruction. Computer programs used to analyze data must be referenced and copies may be requested by the instructor. Approximate Grading Distribution: Preparation Pre-lab Reports and Study Questions 16% Performance Lab Reports 35% Accuracy and Technique 11% (Lab Maintenance up to -1% per day) Theoretical Understanding CPR writing (2 @ 25 each) 8% Exams 30% 3 To receive a passing grade (C-) you must receive at least 50% of the points in each of the three grading areas. Lab technique includes, but is not limited to, attending lab on time and completing the work in the assigned time, leaving your work area and the equipment you use clean and in a condition that the next person can begin work, observing safe practices in the lab, timely submission of lab work, and appropriate contribution to group work and reports. Labs, instrument rooms, and lab areas left in a messy condition will result in a 1% penalty assessed against students in the previous section. Tentative Grading Detail: Asst.

Normal grade assignments are 4 Letter Grade % # Points Letter Grade % # Points C (70-79%) 420-479 points A (90-100%) 540-600 points D (60-69%) 360-419 points B (80-89%) 480-539_ points F (<59%) 0-359 points All grades are final when filed by the instructor on the Final Grade Report. Academic Integrity: All cases of cheating, plagiarism, or dishonesty will be reported to the Dean of Students. All work that you submit for grading must be your own work. Group reports must acknowledge the individual contributions of each person, if the work has been shared. UCLA Extension Administrative Contact for this Course: Seydy Ortiz, Program Rep.
