Tuesday-- 11am-12pm

Thursday-- 2-3pm
The purpose of office hours is to provide you the opportunity to discuss chemical concepts outside of class. Class time does not necessarily offer the time to answer all questions. It is wise to take advantage of this opportunity. While the instructor has set office hours, you may make arrangements to discuss course material at other times.
Objectives: All organic chemists, regardless of their particular area of expertise or interest, need to either understand or be able to accomplish two very important tasks — the construction of carbon-carbon bonds and the manipulation of functional groups. Organic Chemistry I and II are designed to provide a basic understanding of the covalent bond and the chemistry of carbon compounds. By the end of the first semester students should be comfortable with the concepts of structure, nomenclature, conformation, stereochemistry, resonance, and substitution, elimination and addition reactions. They should also recognize the various functional groups that are common to most organic molecules and begin to understand and appreciate some of the reaction processes that are specific to those functional groups. Additionally, it is expected that students will have at least a basic understanding and working knowledge of the important spectroscopic methods (NMR, IR, and UV) that are used for structure identification. By the end of the second semester students should have a general understanding of all of the common organic functional groups and major theoretical concepts. A familiarity with the classic reactions used to incorporate and convert functional groups within organic molecules is also expected. They should have a preliminary appreciation of the details and nuances of synthesizing target molecules, and will have had the opportunity to design strategies of their own. Also, an increased understanding of the methods of structure identification and their application is expected.

Recommended Process to Pass Organic Chemistry:
a) Prepare for lectures by reading the chapters relating to the topics to be covered.
b) Attend the lectures.
c) Recopy your own notes into an alternate notebook.
d) Do the problems.
e) Attend office hours.
f) Do the problems
g) Ask questions pertaining to the notes, problems, and lectures.
The above suggestions are to be taken as a package deal for passing the class. Selection of a few of the suggestions may not be as effective. Experience has demonstrated that to truly learn chemistry, one must do chemistry. In a lecture setting, this means that students must do problems. Simply listening to lectures, reading books, and studying notes does not get the job done. Problems must be worked out. Time must be spent participating in the process of discovery and learning.
Attendance: See "Suggestions to Pass Organic Chemistry", part b. It is your responsibility (and to your benefit) to obtain the missed material and information in the event of your absence from class.
Examinations: There will be three (3), 1 hour, closed book and closed notes exams during the course of the semester. Exams may include material from the laboratory. Exams will be given on WEDNESDAY EVENINGS FROM 8-10pm. Exam dates are 02/21/07, 03/28/07, and 04/25/07. The final exam will be Thursday May 10, 2007 @ 8-10:30am. The final is the American Chemical Society (ACS) standardized exam. All exams must be taken on the designated day and at the designated time unless prior arrangements** are made with the instructor. Failure to do so will result in a zero being recorded for that exam score. No make-up exams will be given.
Homework: It will be highly advantageous if you work the problems within each chapter as you read the chapter. It also will be very helpful if you work the problems at the end of each chapter. It is required that you complete the “suggested problems” for each chapter, listed on the last page of this syllabus, and turn them in to me upon my request, on-time, for full credit.
Cancellations and Make-ups:
UNCA, as a State agency, is expected to provide its service to the public according to its announced calendar and schedules. Therefore, the presumption is that all classes will be taught during inclement weather. On occasion severe weather condition may make it dangerous or physically impossible for teachers and learners to get to campus. The Provost is charged with making the judgment about canceling classes under these conditions.
Each individual student, in the event that classes are not canceled, must assume the personal responsibility of deciding to go to class or not when local road conditions appear too hazardous. In such cases students should inform their instructors as soon as practicable.
The notice that classes are to be canceled or delayed will be broadcast on all local radio stations normally by 6 a.m. The absence of any notice from UNCA signifies that classes WILL BE taught as usual. If a class begins without cancellation notice, it will end at the originally designated time. When we are on a late start schedule, class will be held from 10:55-11:55am. Cancellation notices about evening classes will be provided to the radio stations as soon as practicable after 4 p.m.
The above guidelines have been taken directly from the latest edition of the UNCA Faculty Handbook and serve as the general course policy concerning inclement weather. Policies specific to the different types of assignments are as follows:
1. The instructor may schedule additional class meetings with attendance required if weather conditions have forced cancellation of the equivalent of one full week of class meetings.
2. Exams missed because of class cancellation, will be postponed until the next available class period.
If classes are not canceled and a student misses an exam, no make-up exam will be given and a zero will be recorded for the score. However, if the student meets with the instructor within one week of returning to school, points corresponding to the percentage scored on the appropriate portion of the final exam will be substituted for the missed exam score. Failure to meet with the instructor within this time period will result in a zero being permanently recorded.
Exams missed because of a student's attendance of an authorized school function may be taken at an alternative time if, and only if, prior arrangements are made with the instructor to "make-up" the exam. While all efforts will be made to accommodate the student's schedule when selecting a time for this make-up exam, it is ultimately up to the student to accommodate the instructor's schedule. Failure to do so will result in the exam being treated as if it were missed because of an unauthorized function.
3. Written notice prior to an absence for an authorized school function must be given to the instructor for the student not to be penalized for that absence.
Honor System:
This course will be conducted utilizing the concepts embodied in an Honor System. Your awareness and acceptance of the Honor System will be indicated by your signature in addition to your printed name on all work submitted to me for evaluation. Work submitted to me without a signature will not be evaluated. It will be recorded as a zero and returned so that you may sign and resubmit it for evaluation. Appropriate action will be taken against those found to be in violation of the Honor System (see Academic Responsibilities under Student Responsibilities in the UNCA Catalog).
