Quizzes & Exams: Twelve in-class quizzes (10-15 min. duration) will be administered during
the term and the “best ten” scores for the quizzes will be considered along
2
with other scores when assigning the final grade for the course. The other
two quizzes will be counted as your bonus points for the course. Students
will not be allowed MAKE-UP missed quizzes. In class exams will
consist of multiple choice questions as well as those requiring short
paragraph answers. Under no circumstance will a student be allowed
to make–up a missed exam without a doctor’s note indicating your
inability to attend class on the day of the exam.
The standardized American Chemical Society (ACS) test will be taken as the final exam. “Preparing for
your ACS examination in organic chemistry” is a suggested book to review for taking ACS exam. It can
be ordered online.

Homework: Homework assignments will be provided on Western Online, and will not be distributed in
class. Due dates are posted on the top of all homework assignments. Five homework problem sets (20
pts each) will be given throughout the semester and are due at the beginning of class on their due date
(Homework assignment turned in late (for any reason) will have two point deducted per day;
Homework turned in two weeks after the due date will not be graded.). Each problem set is worth 20
points and will encompass material from your text and lecture. The problem sets will be designed to aid
in your understanding of the course material and act as an additional guide for test preparation.

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. It is the responsibility of the student to inform the
instructor of any necessary accommodations at the beginning of the course. Any
student with a disability requiring accommodations should contact the Office of
Disability Support Services.

Laboratory safety rules










Wear safety goggles (eye protection) at all times when in the laboratory. This is a
departmental and state regulation.
Do not eat or drink in the laboratory.
Know the location and use of the nearest fire extinguisher, nearest First Aid kit, nearest
eye wash station, nearest safety shower, and nearest exit designated for evacuation.
You will be advised of the locations on the first day of the lab.
Know the location of the Material Safety Data Sheets ( MSDS) and know that you have
access to them. You are protected by the right to know law.
Know the NFPA (National Fire Protection Association) Hazardous Material Classification
Codes.
Report all accidents, even minor injuries, to the instructor at once.
In case of an organic chemical spilled on your person, flush with water, wash with soap,
rinse with water, rinse with ethyl alcohol, wash with soap, and rinse with water. Pat dry.
Never taste chemicals or solutions. Minimize the inhalation of organic vapors by using
the smallest amounts of materials and utilizing the hood as much as possible. Check the
MSDS if you have questions.
Dispose of all wastes properly. Read labels on bottles! Keep bench and floor clean.
Before leaving the laboratory, be sure that the water, steam, heaters, and gas cocks are
shut off.
Laboratory Information:
4
Hands-on experience is a vital factor in learning chemistry. Since the laboratory experience is
integral to the overall course, failure to earn a passing grade in the lab will result in
automatic failure for the course. Notebooks will be checked to verify that they contain the
information necessary for the day’s experiment. If a student comes to the lab with an incomplete
pre-lab report or does not seem to be prepared to do the work, that student will not be allowed
to continue in that day’s lab until the lab instructor is convinced of the student’s preparedness
for the experiment.
Lab Notebooks:
It is extremely important to keep a careful and complete record of the experiments in your
laboratory notebook. The laboratory notebook is a record of what happened in the experiment.
It should be understandable to others and should contain enough information such that the
experiment could be repeated at a later date by you or by someone else. Much of the notebook
will be data (descriptions, numbers, calculations, etc.), but a modicum of other information is
also required. Procedural information, changes in method or technique, etc. should be recorded
immediately, providing a complete narrative of everything you do as you are doing it. Therefore,
you will have to do a little writing before, during, and after each lab. A table of contents in your
notebook should also be kept current. Any graphs, computer print-outs, and spectra should be
attached in the notebook (taped or stapled) for a permanent record of the data.
In addition, I would ask for two additional protocols: 1. Leave the first few pages of the notebook
blank for a table of contents so that each experiment can be readily located. Pages should be
numbered consecutively. 2. Write your experimental plan on the left hand page in your
notebook, then record your observations and data on the right hand page.
A sample of recording lab notebook will be posted on WesternOnline. Lab notebook will
be collected twice for the whole semester (20 pts total).
Lab Reports:
The lab will consist of two parts this semester: Three synthesis projects and Identification of four
unknowns.
You will gain experience this semester with methods of identification and methods of separation
of a two-component mixture. You will identify three pure unknown compounds (#1-#3) and a
two-component unknown compounds (#4). You will write reports for all the four
identifications. Report format will be posted on WesternOnline. You will work
independently for identification of unknowns. Identification methods can be found in Part 4:
Identification of Organic Substances in PLKE lab manual and will be discussed in class.
The synthesis projects will be chosen from the designated projects which will be posted on
WesternOnline. You will also work independently for the synthesis projects. Each project will
consist of a two-step synthesis. You will write a scientific paper for each of the synthesis
project. The format and sample of the scientific paper will be posted on WesternOnline.
Late lab reports or problem sets will be deducted by 15% for each week. Lab
reports/Problems sets turned in two weeks after the due date will not be graded.
