COURSE DESCRIPTION, PRE/CO-REQUISITES, TOPICS, AND OBJECTIVES
CHEM 2040L is the
laboratory component of the first semester Organic Chemistry course. Any student taking CHEM 2040L must also be
registered in the corresponding class, CHEM 2040. Departure from this rule
must be allowed by the appropriate authority of the school. CHEM 2040L will
meet once a week for 3 hours each time.
The
experiments conducted in this lab
seek to illustrate the concepts covered
in the lectures. As a result, the topics covered in this lab follow closely
the topics covered in lectures. Learning objectives for this lab include describing and explaining concepts and
phenomena, describing, explaining
and performing the techniques used to determine properties, as well as collecting, processing, analyzing and
interpreting data used in and/or obtained from the determination of the
properties associated with various experiments. Skills learned in this lab include concept understanding, synthesis, application, analysis, and
problem-solving. Computational, drawing or diagramming skills will also be
learned.
* “Organic Chemistry 2040 Laboratory
Manual”. Copies can be purchased
in the bookstore
* Molecular
models.
ATTENDANCE:
Lab
attendance is mandatory. You must attend all labs and perform all experiments.
The only acceptable reports are for labs that were actually attended and
performed. By school regulation, instructors will keep accurate attendance records
and must report the individual
number of absences with midterm and
final grades. Students
whose number of unexcused absences is more
than twice the number of lab meetings per will receive a grade of “F” in the lab. Fewer
absences than twice the number of class meetings per week may result in grade penalties at the
discretion of the instructor. Two
tardiness instances will be equated to one
absence. 2% of the lab grade will be attributed to attendance. Points will
be deducted from the attendance grade proportionally to number of documented
unjustified days of absence. To avoid penalty, any absence will have to be
justified beforehand or immediately after it has happened.
SCHEDULED ACTIVITIES
The laboratory
work will include pre-labs, lab quizzes, laboratory reports, lab mid-term, and
lab final exam. The lab final will be completely comprehensive, covering topics
contained in all labs.
Pre-Lab Reports
and Quizzes
Pre-Lab Reports
and Quizzes
will be done concurrently. They are designed to provide you with enough background to allow you to conduct the labs knowledgeably. They
will be done mostly online, using WebCT. They are to be completed before coming to the laboratory. Otherwise a zero point
grade will result.
Post-Lab Reports
Lab
reports are due two days after the lab
is done. Late labs will receive a grade of zero. The reports must be typed and abide by the following format:
Title: Write the title as given in the
schedule
Date
Author:
Previous authors(2):
Summary:
Say what concept the experiment
illustrates and how it is specifically applied.
Balanced chemical equation(s) for the
reaction(s) used (if applicable).
Procedure:
Shortly
describe the manipulations performed in the experiment. Do not copy the procedure as written in
the manual or handout. It is to be written in the impersonal past tense. For example, a procedure may be reported as
follows: " t-pentyl
bromide was prepared by adding 15 mL of t-pentyl alcohol
to 30 mL of concentrated hydrochloric acid in a separatory
funnel. The reaction mixture was swirled for 5 minutes at room temperature.
After stirring, the mixture was allowed to settle". Write out the procedure based
exactly on what you did, not just
what the procedure says in the manual. Draw a sketch of the setup, if
applicable.
Results:
Briefly
describe the product you obtained
(physical appearance). Indicate the amounts
of product obtained (if applicable), in milliliters (for liquids), grams, and
moles. Determine the percent yield of
your reaction by showing the pertinent calculations and units. This is
especially important in preparative experiments. Include any data collected
pertinent to your observations.
Comments: Express your opinion about the quality &/or quantity of the
results.
Questions: Answer any
homework questions asked at the end of the lab.
TESTS.
There will be one lab mid-term and one lab final tests. Both tests will have equal
weights.
The midterm will
cover the material of the experiments performed up to that time. The final
test will cover all the material of the semester. The tests will
seek to assess students problem-solving skills gained as well as the ability to
understand the concepts which govern the experiments run in the lab. Test (and
Quiz) questions will be a combination of
multiple choice and essay types.
Instead of a
mere statement of facts, a typical multiple
choice question will be a statement
of fact and its justification. This not only better demonstrates knowledge
of the material, but it also limits to a minimum the probability of obtaining a
high grade through picking the correct answer by mere luck.
Even though
they take a considerable amount of time to grade, essay questions provide better insight
into student knowledge and thinking process, which allows for better
intervention to improve student knowledge quality and level when such
intervention is warranted.
Compelling
and verifiable reasons only will be accepted in order to make up a missed
midterm test. The make-up test will be done at the time of the final
examination, only if it was pre-approved at the time the
corresponding regular test was missed. No make-ups will be allowed for the final test.
EVALUATION.
The laboratory
grade will be determined from the evaluation of pre-labs, lab quizzes,
laboratory reports, lab mid-term, and lab final exam. The lab final will be
completely comprehensive, covering topics contained in all labs.
The
pre-labs and quizzes will be averaged
together to count as one lab test on
your final lab grade. Similarly, lab
reports will be averaged together to count as one lab test. The mid-term and the final exam will be the other
major components. 2% of the lab grade
will be reserved to the conduct in lab,
including adherence to safety rules. 2
points will be deducted from the grade at every violation.
The lab grade will be made of the
following components:
1. Pre-labs & Quizzes = one test
2. Lab Reports: one test.
3. Mid-term test
4. Final test.
Overall: 4 performance
items, each carrying 24% of the total lab grade.
5. Attendance and Conduct: 4% of total lab grade
Total %: 100%
Grading Scale & Percentage/grade
conversion
Percentage Grade
90-100 % A
80-89 B
70-79 C
60-69 D
0-59 F
LOW
PRELAB AND REPORT GRADES
If
the final test is higher than the
mid term grade, the mid term grade may be dropped. However the grade to be
dropped must be in a position to affect the letter grade of the lab in order to
justify its removal. However the grade to be dropped must correspond to a test
that was actually taken. A skipped test does not apply.
LEARNING
DISABILITIES: Students with learning disabilities or physical disabilities
will be accommodated as best as possible. The learning disability must be properly
documented through Student Services. Any student who fulfills learning
disabilities conditions must get in touch with the teacher in order to insure
his/her case will be dealt with properly and in a timely manner.
WITHDRAWAL FROM THE COURSE
CHEM
2040L is a co-requisite of CHEM 2040.
Dropping one leads to dropping the other.
ACADEMIC
DISHONESTY
Cheating,
plagiarism or any other form of dishonesty is strictly prohibited. Sanctions
will be imposed on anybody caught in the act. The source and the beneficiary
will be punished equally. Depending on the gravity and / or frequency of
misconduct, the punishment could amount to failure in and dismissal from the
class. Academic dishonesty as defined in
the Abraham Baldwin 2007 Catalog will not be tolerated. All infractions will be
dealt with according to the procedures outlined in the Catalog. Sanctions may
include a zero on the assignment or even failure in the class. Students are
recommended to read and review this material. See page 57 of the 2007 ABAC
Catalog.
CAP/HAT/ELECTRONIC
DEVICES POLICY
No caps/hats will be allowed on examination days and when/if quizzes are
given. Furthermore, the use of any device which can deliver and/or receive
electronic messages will be strictly prohibited. The source and the destination
of the messages will be sanctioned equally.
EYE AND HAND
PROTECTION: Students
are required to wear eye and hand protection at all times in the laboratory.
Students not wearing goggles and gloves in the lab will be asked to leave and
no credit will be given for that particular experiment. In requiring that
students wear goggles and gloves, the need for safety in the lab outweighs the
need for comfort.
GENERAL SAFETY
AND LABORATORY RULES:
1. Be familiar with laboratory procedures and safety
precautions to be carried out before coming to lab. If you are at all in doubt
as to any procedures or safety measures, consult with your instructor.
2. Be aware of what is happening around you at all times.
3. Use common
sense at all times when in the lab.
4. Listen very
carefully to any safety procedures and cautionary measures discussed by your
instructor. Ask questions if you still are uncertain of any safety procedures
and cautionary
measures.
5. Wear older,
less valuable clothing (preferably cotton or wool) if possible. If you must
wear nicer clothing, wear a lab safety coat. Some safety coats will be made
available in the lab.
6. Never eat or
drink in the lab.
7. Wash your
hands immediately after contact with any lab chemicals. Always wash your hands
before leaving the lab.
8. Wear closed,
leather shoes and long pants or skirts (something to protect your legs).
9. Don't wear
eye contacts in lab if at all possible.
10. Tie up long
hair.
11. Help look
after your lab partner and others around you.
12. Exercise
special care whenever you are using flammable chemicals.
13. Never
perform unauthorized experiments.
14. Learn the
location of the eyewash stations and safety shower.
15. THINK
SAFETY AT ALL TIMES.
LEAVING THE LABORATORY: See
number 7 under General Safety and Lab Rules. Clean up your area before
leaving. Points will be taken off for leaving the work place dirty.
MISSED LABS: A missed lab can't be made up after the
week when it was on schedule. A valid reason for missing the scheduled lab must
be given and accepted before a student can make up a lab in section other than
the one in which he/she is registered. If unable to make the lab up and if
missed for an acceptable reason, the missed lab will not affect the grade. If
missed for an unacceptable reason, the missed parts of the lab will receive a
zero.
