Prelabs. Due before beginning the experiment. The purpose of prelabs is to prepare you for the
experiment. Make sure you read and understand the lab. I will post the prelab questions ahead of time
before the experiment.
You may not begin the experiment until the prelab section is completed and checked by instructor.

POST LAB QUESTIONS: I will post on the blackboard the postlab questions. The purpose of postlab
questions is to see whether you understood the techniques you performed during the experiment.
LAB REPORT
NOTEBOOK
Notebooks must be written legibly to avoid loss of points.
 TITLE
 DATE
 PURPOSE Describe what is expected of the laboratory. This should be only one or two sentences, in
your own words--do not copy from the manuals.
 PROCEDURE A flow diagram is best. Abbreviated version of what you will be doing. Read the lab and
be familiar with what will be happening. Summarize the steps.

 DATA TABLE Listing of all of the reagents and solvents used in the experiment. List in table form
only.

CHEMICAL EQUATIONS Write all of the major chemical reactions and side reactions for the
experiment. Include the amounts called for in the experiment (which is the limiting reagent?) and the
theoretical yield. Not necessary for the distillation, melting point, or crystallization experiments.

OBSERVATIONS All data and everything that occurs in lab as it happens. Colors, smells, amounts used,
mixing, temperatures, apparatus used, time for reaction, spills if they occur etc.
appropriate, use tables, graphs, equations, etc.
Draw pictures if
Record details such as Instrument name and maker,
model number and serial number, chemical manufacturer, grade, lot number, expiration date, etc.
This section cannot be too long. Spectra are also to be included with this section. Due at the end of
lab.

CONCLUSION Write the final conclusion
FORMAL REPORT : You will write a formal report on Friedel Craft Acetylation one lab. This report
should be written in the form of a scientific journal.
METHOD OF EVALUATION:
A straight percentage is used to determine grade.
A = 90%
B = 80%
C = 65%
D = 55%
MAKE-UP POLICY:
4
No make-ups are allowed for the experimental or discussion portion of the class. Late laboratory reports
will be deducted 5 points per day (including weekends).
ACADEMIC HONESTY POLICY: Any student found cheating, including plagiarism, will be subject to the
penalties as stated in the Student Code of Conduct handbook; including but not limited to a score of zero
on exam, review or report, expulsion from the class or expulsion from the University.
ATTENDANCE POLICY:
Attendance is mandatory. This is a laboratory class. You must be present to complete the requirements.
If you miss one (1) laboratory with an excused absence I will recalculate grade. Unexcused absences
result in a zero for that experiment.
SEMESTER WITHDRAWALS: The last day to withdraw from the class with a “W” is 4th April 2012.
ACADEMIC DISABILITIES POLICY: If you have a documented disability that requires assistance, you will
need to register with the Office of Disability Services for coordination of your academic accommodations.
The Office of Disability Services is located in Peltier Hall, Room 100-A. The phone number is (985)
448-4430 (TDD 449-7002).
ACADEMIC GRIEVANCES. The proper procedure for filing grade appeals or grievances related to
academic matters is listed in Section 5 of the Code of Student Conduct and at he following link:
http://www.nicholls.edu/documents/student_life/code_of_conduct.pdf .
CONTINUED LEARNING FOLLOWING AN EXTREME EMERGENCY:
In order to make continued learning possible following an extreme emergency, students are responsible
for:
 reading regular emergency notifications on the NSU website;
 knowing their Blackboard (or designated system) student login and password;
 knowing how to use and access Blackboard (or university designated electronic delivery system);
 being familiar with emergency guidelines;
 evacuating textbooks and other course materials;
 contacting faculty regarding their intentions for completing the course.

Faculty are responsible for:
 their development in the use of the Blackboard (or designated) software;
 having a plan for continuing their courses using only Blackboard and email;
 continuing their course in whatever way suits the completion of the course best, and being creative
in the continuation of these courses;
 making adjustments or compensations to a student's progress in special programs with labs,
clinical sequences or the like only in the immediate semester following the emergency.
CLASS DISRUPTIONS: The use of cellular phones, pagers or any other electronic personal devices is
prohibited in class. Any infractions will result in class being dismissed and experiments considered over.
This includes but not limited to
 using your phone as timer—get a watch or I will supply stopwatches if needed,
 going to the hallway while a experiment is ongoing to check on texts.
 texting or calling or receiving incoming calls or texts
 receiving alerts regarding incoming texts or calls
5

using phone as alarm system.
Note: This is not a binding contract. This syllabus is subject to change throughout the course.
