Pavia, Lampman, Kriz, and Engel, Introduction to Organic Laboratory
Techniques: A Microscale Approach, 4th
ed. (abbreviated PLKE)

Course
purpose: This course is the first
quarter of the two-quarter organic chemistry lab series. It will introduce you
to various organic chemistry laboratory procedures and techniques, including
simple syntheses, separations, extractions and purifications. In addition, you
will learn about infrared spectroscopy and its use in organic compound
characterization. Finally, you will become familiar with organic chemistry lab
safety procedures and working with extremely small quantities of chemicals. CHE
231 is a prerequisite for the course.

This schedule is subject
to a minimal amount of change.
Lab lecture: I will give a short lecture on each lab at the
beginning of the meeting prior to when you will be performing the experiment.
You are responsible to obtain notes from a fellow student if you miss a
lecture.
Attendance: In general, you will be performing the
experiments individually, so you cannot rely on another person to get lab data.
Show up to every
class meeting. Due to space and
time constraints, you cannot
make up an exam or a lab. If you miss a lab, you cannot make it up and you will
receive a 0. *At the end of the quarter the lowest lab score will be dropped,
which is why even though there are 16 lab days, there are only 210 points
possible from lab reports.
Lab
reports will consist of
(sometimes) a pre-laboratory exercise (ÒprelabÓ) and (always) a lab results report.
The
pre-lab should be written in your
notebook and a photocopy should be given to your instructor at the beginning
the experiment. You will not be allowed to start the experiment unless the prelab is complete. The prelab will generally
consist of a purpose and a materials
and methods section, unless that
particular lab calls for something else (check the individual lab handout).
1)
The purpose section
is a few sentences outlining
the experimentÕs objective(s).
Mention what techniques
you will be using, what data
you are collecting (and why you are collecting it) and, if appropriate, what compounds you are synthesizing. It is also appropriate to include any synthesis schemes (i.e., chemical equations using organic molecule
representations).
2)
The materials and
methods section should contain the experimental procedure in your own words (including sketches of apparatus).
This section should also list the reagents (and quantities) used, and indicate possible
side reactions and by-products.
See pages 563-564 of PLKE for an example.
The
lab result report is based on the
handout that will be posted on the course web page prior to the lab date. The
report handout will have some questions to be answered.
Lab reports will be due at the beginning of the lab period immediately after the period in which the experimental work is
finished. The entire lab
report must be turned in at the same time. Reports turned in after the beginning of the lab period will
be marked late. Lab reports turned
in up to one day late will be marked off 25%. Lab reports turned in between 1-7
days late will be marked off 50%. Lab reports turned in more than one week late
will be given no credit.
Even though you will
complete the experimental work in pairs, all lab report must be written up
individually. Although you may
discuss the lab report with other students, the report must be written in
your own words. If there is
evidence of copying for any part of the lab, all students involved will receive
a grade of zero on the lab report. If this happens a second time during the
quarter, you will receive a grade of zero on the lab report and your grade in
the course will be dropped one full grade point. Plagiarism and cheating are
quite serious offenses in academia.
Lab
notebooks: Purchase a bound notebook at the bookstore or other supplier. Spiral notebooks are not acceptable.
When performing an experiment, write down the procedure as you do it and
note all observations. During all
times in the lab, you must have your lab notebook open and you must record
data/observations in real time, i.e., as you see it. A good lab notebook is one
that would allow another person to replicate the experiment using only your
notebook. Please read the section
on ÒLab NotebooksÓ on page 558ff. of PLKE. At the end of the quarter, I will
collect your lab notebook to give an overall assessment of the completeness,
neatness and professionalism your notebook displays – this will
translated to a score out of 30 points.
Tests and lab practical exam: Since this is to assess individual learning, all that follows will be
done without collaboration with other students. There will be two written
exams, each worth 50 points, covering the material in the course up to that
point. Since it is to assess your understanding of the course material, and not
so much your fact recall, the written exams are open lab notebook (but closed
textbook and other resources). The lab practical exam will require that you
perform either a crystallization or an extraction procedure. Again, you will
not be able to use the textbook, but you will be able to use your lab notebook.
Subjective grade:
This is my assessment of your ability to perform organic chemistry techniques
efficiently, intelligently and, above all, safely, which means there may or may not be a safety
quiz as part of this grade. In addition, I will also be assessing your use of
the lab notebook at appropriate times and your ability to follow instructions
and work with your colleagues – all of this will be translated to a score
out of 20 points.
Chemical sensitivities: Due to the increasing numbers of individuals
developing chemical sensitivities and the increasing awareness of such
conditions, everyone who attends this class is asked to refrain from wearing
any fragrance or perfume. The greatest feasible efforts will also be taken to
ensure a fresh air environment free of not only the above-mentioned fragrances
but also potentially harmful substances such as carbon monoxide, formaldehyde,
carpet odor, organic solvents, etc. Individuals who are unsure of the
importance of this policy should see the Associate Dean for additional
information. Also, if you are pregnant or nursing, you should discuss the
situation with your doctor.
Cell phones and pagers: Please turn these devices off or switch them to
ÒvibrateÓ mode during class.
