C. Course
Description
Intended for life science majors. This laboratory
course is designed to accompany CHEM 3053 and 3153. Selected experiments are designed to
illustrate the fundamental techniques used in organic chemistry, to develop
familiarity with the properties of organic compounds, and to introduce
analytical techniques including chromatography and spectroscopy.
By the end of this course, the student
should be able to
· Carry out
chemical reactions, work up, separate, purify and analyze the products. Manipulate
synthetic apparatuses and glassware.
· Carry out
mathematical procedures necessary in organic synthesis and analysis.
· Interpret
analytical data (melting point, boiling point, thin layer chromatography,
column chromatography, gas chromatography, infrared spectroscopy, NMR
spectroscopy, mass spectrometry) to verify the product/composition of a
reaction.
· Explain the
procedures and concepts of basic organic laboratory, synthetic and analytical
techniques.
· Communicate
the outcome of an experiment to scientific audience.
The course grade will be determined by
the average of lab notebook, problem sets, quizzes, mid-term exam, and final Exam.
The final letter grading for the lecture course will be as follows: A = 500-450,
B = 449-400, C = 399-350, D = 349-300, F = <300. Generally the class will
not be curved, but it’s the instructor’s decision to make any adjustments in
order to normalize the grades among individual sections.

E. Lab
Notebook
See the guidelines on page 9 of lab
manual (iBook or PDF version). Each lab report is worth a set of 20 points,
which is distributed among (i) pre-lab, (ii) lab observation and (iii)
post-lab. Use ink pen to write on lab notebook and turn in the carbon copy
pages for grading. Your writing should be distinct from your lab partner’s,
though the experimental data are same.
It should be legible to read and grade. You should attach a grade sheet
(given on D2L) to your report. The pre-lab for each experiment may take a
couple of hours to prepare properly and it is important that the student
understand the intent and purpose of the experiment before attending the
lab. Your TA would sign in and sign out
on your notebook for each experiment. The discussion part of a lab report
should address all learning objectives given on D2L. Lab reports are due by the end of next lab meetings
(i.e., one week after the completion of the experiment). No late lab reports
will be accepted. Typed or “original” notebook
pages will not be accepted. The
individual laboratory TAs will grade lab notebook assignments.
F. Problem
Sets
Problems sets are to test students’
understanding of background and procedure of an experiment. Print the problem
sets given on D2L, work out the problems and turn in at the beginning of the
lab. Students will not be allowed to do experiments without the problem
sets.
G. Quizzes
Quizzes may test material from previous
laboratory experiments, from the background and pre-lab for the current/next
experiment, and from the lecture. Most
quizzes will consist of theoretical, practical, and calculation questions. The quizzes will be given during the lecture
on the days listed on the schedule.
H. Exams
The Exams will cover material from the
lecture materials, class discussion, the background in the laboratory manual,
learning objectives and discussion. Therefore,
it will test the students’ understanding of both the theoretical knowledge of
the conceptual material and the practical knowledge of the actual techniques
and operations of the laboratory techniques. The exams will be prepared by the
instructor and will be uniformly graded under the instructor’s
supervision.
I. Communication
For most questions about the laboratory,
see your laboratory TA. They can handle
the majority of your questions directly.
For questions about the laboratory grades, the exams, or the
administrative aspects of the laboratory, please contact the instructor. For
questions about the lecture material or concerning the D2L site and materials,
please contact the instructor. It is always better to visit office hours for
quick response. TAs’ office hour are listed in the attachment.
You have the responsibility to read and
respond to any email messages sent by the instructor or the TA. Messages will
only be sent to OU accounts. Use CHEM3152 in the subject line of your emails to
enable proper filtering. The instructor will attempt to respond to emails by
the following weekday. More general questions will be addressed in the
following lecture.
J. Make-up policy
No make-up labs will be offered. Due to space and safety concerns, it is not
feasible to schedule make-up labs. Also since many chemicals are freshly
prepared before each lab section, it is not possible to use them for make-up
labs.
As the best 11 out of 12 lab grades will
be counted, the least scored lab will be automatically dropped. If a student
misses two lab experiments for a University-sponsored or legally required
activity, both days that the student was absent must for an excused
reason. The student that misses two lab
days due to an acceptable reason will have their grade scale adjusted by
removing that day’s lab experiment from the total points. The missed lab will not have an impact on the
student’s grade, but this will increase the impact of the remaining grades on
the final average and grade. If a
student has missed two lab days but only one of the days was acceptable reason,
then the assignments for the excused day will be dropped and the other day’s
assignments will receive a grade of zero.
If a student misses more than two lab experiments, it is recommended that
the student contact the instructor to discuss the situation. A student cannot receive a grade for a lab
experiment that they did not attend and complete.
Examples of the provost-approved
university-sponsored activities are scholarly competitions, fine arts
performances, and academic field trips.
It is also the policy of the University to excuse absences of students
that observe religious holidays.
Examples of legally required activities are emergency military service
and jury duty. The instructor also
reserves the right to excuse an absence to a lab or exam in cases of immediate
medical emergencies and family deaths.
A make-up exam/quiz may be offered. If a student misses an exam/quiz for a university-sponsored
or legally required activity, the student should contact the instructor before
the exam/quiz. An equivalent exam/quiz will be prepared and a time to take the
exam/quiz will be scheduled before the end of the week. The instructor also
reserves the right to excuse an absence to an exam/quiz in cases of immediate
medical emergencies and family deaths.
Make-up exam/quiz will not be offered unless the instructor is contacted
by e-mail before the exam /quiz starting time. The student should produce a
letter from authorized person to excuse the absence before taking the make-up
exam/quiz.
Laboratory drawer check out will
be conducted at the end of semester on the given date. Students must show-up on
that day to avoid the no-show-up fee $75.
K. Safety Policy
See the appendix
“Standard Operational Procedures in the Organic Chemistry Laboratory”
Proper attire in the lab is important
for your safety. Therefore, a student
will be asked to leave the lab if they are not dress appropriately for the
lab. In general, all of the student’s
skin should be covered except for the lower arms and hands (up to mid-bicep)
and the neck and head. A good
description of what would be acceptable dress would be tennis shoes,
full-length pants, and a short sleeve T-shirt. Shoes should contain and cover the full foot. Pants/Skirts/Dress should cover all the legs
to the ankle and up to the shirt/top.
Shirts/Tops should cover from the pants/skirt to the neck and mid-bicep.
Laboratory goggles should be worn at
all times in the lab. There are
several experiments where gloves are required.
Students should wear gloves during all experiments although the department
may not supply gloves for experiments in which they are not deemed essential.
The students should be focused on the
experiment being performed during the lab.
Therefore, the use of a cell phones, audio devices, video devices,
and tablets are prohibited during the lab.
The students should also not be reading course material unrelated to the
laboratory or completing assignments from other courses. The TA has the right to ask the student to
put away any material not related to the lab or to leave the lab room (this
impact the student’s grade).
L. Academic Integrity and Honesty
All students are expected to conform to
college-level standards of ethics, academic integrity, and academic
honesty. By enrolling in this course,
you agree to be bound by the Academic Misconduct Code published in The
University of Oklahoma Student Code (www.ou.edu/studentcode/OUStudentCode.pdf). For further clarification please see: www.ou.edu/provost/integrity-rights/.
All members of the community recognize
the necessity of being honest with themselves and with others. Cheating in
class, plagiarizing, lying and employing other modes of deceit diminish the
integrity of the educational experience.
None of these should be used as a strategy to obtain a false sense of
success. The need for honest relations
among all members of the community is essential.
Any instance of a student receiving any
type of help on an exam or quiz from another person or any source (notes,
online, etc.) not authorized by the instructor shall be considered academic
misconduct and, as a result, will be penalized to the fullest extent possible.
M. Electronic
Communications/Storage/Recording Devices:
All students should have cell phones off
or silenced. If you are anticipating an emergency, you may have your cell phone
on and set to vibrate. In such a case, you should let the instructor know in
advance and situate yourself near a door so you can take the call outside the
room with a minimum of disruption to class. Sending and/or receiving text or
other electronic media is considered inappropriate, including if you use an
electronic device to take notes that can send/receive messages of any kind. If
inappropriate messaging is observed you may receive a grade penalty or be asked
to leave (see Academic Integrity and Honesty). Electronic recording of lectures
(pictures, video, audio, etc.) is prohibited unless written permission is given
by the instructor in advance.
N. Accommodations:
Any student in
this course who has a disability that may prevent him or her from fully
demonstrating his or her abilities should contact me personally as soon as
possible so we can discuss accommodations necessary to ensure full
participation and facilitate your educational opportunities. Students requiring
academic accommodation should contact the Disability Resource Center for
assistance at (405) 325-3852 or TDD: (405) 325-4173. For more information please see the
Disability Resource Center website
O. Modification of the Syllabus
Though the
main points of this syllabus are unlikely to change, the instructor reserves
the right to modify any part of this syllabus.
Appendix
Standard
Operational Procedures in the Organic Chemistry Laboratory
Any student
working in an unsafe manner may be dismissed from the laboratory by an
instructor.
1. Laboratory
Notebook
a. For each
experiment students must keep a written record of their work. In many
scientific professions, laboratory notebooks are legal documents containing
background information, repeatable directions, observations, data,
calculations, results, conclusions, and spectral analysis in a permanent
format.
2. Preparation
a. Pre-Lab
i.
Students will have the prelab and procedure written and completed
before coming to class.
ii.
It is the student’s responsibility to obtain their TA’s signature
at the beginning and end of the class.
iii.
Pre-lab problem sets must be turned in at the beginning of class
before starting the experiment for the day.
b. Procedure
i.
Students will have a thorough, concise, and bulleted procedure
ready before coming to class.
ii.
Laboratory manuals are not allowed to be used during the
experiment. The student’s procedure should be detailed enough to allow anyone
to follow the instructions and complete the experiment.
3. Attendance
& Participation
a. Laboratory
experiments are held each week unless otherwise instructed. Mandatory
attendance is required to get a grade for the experiment. Preparation,
efficient and appropriate use of time, attention to detail, staying on task,
and a willingness to learn and participate are valuable qualities that will
lead to a successful lab experience.
b. No make-up
labs are given for CHEM 3152.
c. Students
will work in groups of two unless otherwise instructed. Both students should
participate equally in the lab.
d. Students
will turn in individual lab reports that are reasonably different from their
partner’s work.
e. Students
should attempt to check their e-mail at least once a day to look for additional
important information
4. Working
Environment
a. No food,
drink, or chewing gum is allowed while in the lab.
b. Students
should disassemble and return common equipment to the TA, drawer, or cabinet at
the end of the lab period.
c. Students
should complete all lab work and clean up by at least ten minutes before the
end of lab. Students should be out of the lab on time to allow for the next
class to be prepared.
d. It is a good
idea that students wash their hands before leaving the lab. Even if gloves were
used, residual chemicals may still be present on the skin.
e. Students
should wash glassware, clean the workspace area, and put the stool on the
counter at the end of the lab period unless otherwise instructed.
f.
Students should take care to not contaminate chemicals, standards,
solutions, or solvents by using the same pipette or spatula in different
containers without cleaning and drying the item thoroughly first.
g. Students
should not sit or lean on the counters as there may be chemical residue
remaining which may damage the skin or clothing.
h. Students
should not leave the lab while wearing gloves or lab coats.
5. Glassware
a. Students
should keep their glassware reasonably clean throughout the experiment.
b. Glassware
should be cleaned at the end of each laboratory experiment.
c. Never use a
thermometer as a stirrer! Always support a thermometer in a beaker or flask
with a clamp. If a mercury thermometer breaks, immediately contact the
laboratory instructor and restrict access to the area of contamination until
cleanup can be arranged.
d. Students
should immediately report all breakage of glassware to their instructor for
disposal instructions. All glass breakages must be immediately recorded on the
student’s breakage card.
6. Safety
a. Safety
policies and procedures are given in both the syllabus and the laboratory
manual. All safety policies must be followed by all people entering the Organic
laboratories.

c. If you wear
contact lenses, try to avoid wearing them in the lab. If you must wear contact
lenses, your goggles must seal particularly well to your face.
d. Students
should be familiar with the locations of the exits, eyewash stations, safety
shower, and first aid kit.
e. Fire
extinguishers are restricted to the use of persons who are properly trained.
Small fires may be extinguished by covering with a beaker or larger container.
7. Heating
Equipment
a. No open
flames are allowed in the organic lab!
b. Reactions
that are exothermic and/or being heated must be monitored. Do not leave them
without having your partner present to keep an eye on the reaction.
c. Turn off
electrical equipment immediately after you have finished unless your instructor
has stated otherwise.
d. Never heat a
closed system. Pressure will build up and cause the glass to fail. This could
result in glass projectiles being sent in all directions.
8. Waste
Disposal
a. Students
should record waste properly by spelling out all the components on both the
liquid and solid waste sheets. No abbreviations, formulas, or symbols are
allowed.
b. Do not
dispose of waste by pouring it down the drain or throwing it away in the trash.
Dispose of waste in the proper location. If the student is uncertain, the
laboratory instructor can provide the correct information
9. Electronic
Usage
a. All students
should have cell phones off or silenced. If you are anticipating an emergency,
you may have your cell phone on and set to vibrate. In such a case, you should
let the instructor know in advance and take the call outside the room with a
minimum of disruption to class. Sending and/or receiving text or other
electronic media is considered inappropriate, including if you use an
electronic device to take notes that can send/receive messages of any kind. If
inappropriate messaging is observed you may receive a grade penalty or be asked
to leave. Use of iPods, iPads, music players, computers, or other electronic
devices are prohibited while in the lab unless written permission is given by
the instructor in advance.
