Course Objective
• To know and understand the bonding and structure of organic compounds
• To appreciate the dependence of molecular properties on that bonding and structure
• To know the reaction of organic
• To develop practical laboratory experience in modern organic chemistry
Outside work requirements for the course
Students are expected to review, study and learn all material discussed in lecture, as well as read assigned chapters in the textbook, and to work assigned practice problems/questions/terms listed in class or on Western Online. Generally a minimum of 2 to 3 hours of outside study time is required for each hour of class time for this course.

LECTURE TESTS, HOMEWORKS AND QUIZZES
Three lecture exams (each worth 100 points), three homeworks (each worth 50 points) ten quizzes (each worth 15 points), and a final exam worth 150 points will be given. Make-up quizzes and make up exam will be given for those with excused absences. Only two make-up quizzes and one make-up exam will be allowed. Make-up exam has to be done within one week of original scheduled test day. Excused absences are defined as documented illnesses, military service requirements, and family emergencies. All excused absences must be approved by the course instructor.
ATTENDANCE
You are expected to attend class regularly and punctually. All students are responsible for all information and materials given in class whether you are present or not.Excessive absences will be reported to the financial aid office and your academic advisor. Attendance at the laboratory is required and will be checked for each lab. Only one make-up lab is allowed with good excuses as mentioned under “Exams and quizzes.”
Please turn off cell phones and beepers while in class out of consideration for your classmates. It can be very distracting- especially during an exam! Also, class time is not a social hour; please refrain from casual conversation during class time.

Final Examination will be a Comprehensive One
Homework: Since critical thinking and problem solving are important components of chemistry, homework will be assigned regularly and posted in WesternOnline in order to help students grasp principles and concepts discussed in class. Regular practice will help your overall exam scores.
Web Resources: The course homepage is on the Western Online. Information for this class will be posted there, including the course syllabus, homework problem sets, quizzes, exams, their answers and your grades. Any class announcements will also be posted here.
Emergency evacuation: If a fire alarm should happen to ring, or if students are ordered to evacuate a lab or classroom by the instructor, the students should walk to the nearest stairwell (Do not use the elevators) and proceed to the ground floor and out the building. Any student on an upper floor who cannot physically proceed down the stairs should go to the southernmost stairwell and await assistance. If the building should be evacuated all students and personnel should gather at the southwest corner of the Higgins Parking lot near the fence (parking lot just outside the building) to wait further instructions.
Also, the campus emergency management office has two videos at the beginning of the semester. These videos are titled "Shots fired and College Fire Survival" and can be found at the following web site: http://www.wiu.edu/rmep/resources.php.
WIU Policies: It is the policy of Western Illinois University to accommodate individuals with disabilities pursuant to federal law and the University's commitment to equal educational opportunities.

Chem 102 Lab Syllabus
Time: Tuesday: 8:00-10:50 am; 11:00 am-1:50 pm; 2:00-4:50 pm. Thursday: 8-10:50 am;
Place: CURRENS HALL 427
Lab Manual: http://www.wiu.edu/users/mftkv/Chemistry102/
Experiments: Each student is expected to successfully complete 10 experiments.
· Lab Reports: Use of laboratory note books (with duplicate copies) is mandatory. No excuses!!!
Laboratory reports will consist of three parts: pre-lab questions, report sheet and post-lab questions. The report should be hand written legibly. Each complete lab report is 20 points.
Pre-lab questions (5 pts) : The pre-lab questions are to be completed before coming to lab. Your instructor will check your pre-lab report at the beginning of each laboratory period. One will not be permitted to perform an experiment without completing the pre-lab section of the lab report before the start of the lab.
Pre-lab section of the write-up will consist of:
Title
Purpose
Chemical Equation (if applicable)
Procedure (A detailed procedure in your own words)
Answers to pre-lab questions.
Report sheet (10 pts): Report sheets include experimental data, calculations and observations. Report sheet should be recorded during the lab.
Post-lab questions (5 pts): All questions should be answered unless otherwise indicated by your instructor.
Post-lab section of the write-up will consist of:
Legibly recorded data (hand in the duplicate copy)
Results and Discussion (what was learned)
Conclusion
Answers to post lab questions
Lab report should be submitted at the beginning of the next lab period. Late lab reports will be docked by 3 pts per day. Lab reports turned in one week after the due date will not be graded.
Penalties:
The late penalty for laboratory reports are as follows: (1) Without a duely completed pre-lab portion of the report no one will be allowed to carry out the experiment. (2) Post-lab reports are due a week from completing the experiment ( see below).
Request for regrading a laboratory report should be made within two weeks of recieving the graded report back.
Lab reports turned in two weeks after the due date will not be graded.
Attendance: Attendance is required. One and only one make-up lab is allowed at the end of the semester. You must attend the lab section that you are signed-up for. Cell phones are not to be used in the lab, and should be turned off and put away during lab period.
Grading: The instructors will collaborate so as to grade each lab section in a uniform manner. Overall, the lab will count as 250 points and it will be added to your lecture portion points to tabulate a final grade for this course. Failure to complete the lab with at least 60% (>150 points out of 250 lab grade) will result in failure for the Lab. Since the laboratory experience is integral to the overall course, failure to earn a passing grade in the lab will result in an automatic failure for the course.
Statement on Ethics. Western Illinois University, like all communities, functions best when its members treat one another with honesty, fairness, respect, and trust. Students have rights and responsibilities. The following action is prohibited under the Student Conduct Code: Disorderly Conduct: Any behavior which disrupts the regular or normal functions of the University community, including behavior which breaches the peace or violates the rights of others. Plagiarism, cheating, and other forms of academic dishonesty constitute a serious violation of University conduct regulations. Any student convicted of academic dishonesty, can receive a failing grade and may be subject to further academic penalties. Web address for Academic Integrity Policy (http://www.wiu.edu/policies/acintegrity.php). Please remember that you are expected to do your own work at all times. You can’t directly copy the homework or lab report from your classmates or other sources. However, discussing homework questions or lab reports with your classmates and others is fine.
