    Sections 001 and 002 will be in LAB 208 CPB

    ALL BRIEFINGS ARE IN ROOM 114, CHEMISTRY RESEARCH BUILDING (CRB)

Dr. Edward Bellion (CPB 350, Tel. 817-272-3802, bellion@uta.edu)is the faculty supervisor for CHEM

    2182. Dr. Bellion‟s office hours are 11:00-11:59 am, Tues. & Wed. Information about various aspects of CHEM 2182 will also be available on the following web site:

    (http://www2.uta.edu/chemistry/Classes.htm).

Students enrolled in CHEM 2182 must have credit for CHEM 2181 and should also be enrolled in CHEM

    2322 or have prior credit for CHEM 2322 or an equivalent course. Others will be dropped from 2182.

    Students enrolling in 2182 with the intention of replacing a previous CHEM 2182 grade must declare their

    intention to do so at the registrar‟s office by the census date (June 8) for this semester. If you are dropped

    from this class for non-payment of tuition, you may secure an Enrollment Loan through the Bursar‟s Office. You may not continue to attend class until your Enrollment Loan has been applied to outstanding

    tuition fees.

This laboratory course is intended to familiarize you with many of the common procedures and techniques

    for preparing, identifying, and purifying organic compounds. You will also gain some practical knowledge

    of the use of spectroscopy in identifying organic unknowns. On completion of this course it is expected

    that you will:

    a) know how to correctly assemble and operate common laboratory glassware and equipment required for

    the synthesis, purification, and identification of organic compounds.

    b) demonstrate habits of careful workmanship in the laboratory, including skills of observation,

    measurement, and record-keeping.

    c) perform laboratory work in accordance with accepted regulations with due regard for your own and

    others‟ safety.

    The laboratory text is Experiments for Organic Chemistry II. Please read the PREFACE of the manual prior to coming into the lab for the first time. You should read and be familiar with all of the assigned

    experiments before they are scheduled to be performed. You should also complete the appropriate pre-lab

    exercises in your notebook before starting the experiments. You will be taking a brief quiz before starting

    an experiment. You will not be expected to answer questions or do any procedures involving spectroscopy,

    i.e. NMR and IR, this semester.

Required Lab Attire. READ THIS INFORMATION VERY CAREFULLY!!! You will be exposed to

    hazardous chemicals in chemistry lab. Certain personal protective equipment is necessary to protect your

    body. You will not be allowed to attend lab if you are in violation of the following rules. If you are not

    dressed appropriately, you will need to leave the lab. All missed lab work will count as zero! 1. Goggles, gloves and aprons are provided and are required at all times.

    2. Shoes that cover the entire foot are required at all times. No sandals, mocs, Crocs, etc, even with socks. Absolutely no exceptions will be made to this guideline. Warnings will not be issued.

    3. Long pants and sleeves are highly recommended. 4. No musical or other entertainment devices may be used in chemistry lab at any time.

    5. Cell phones are not permitted in lab and must be put in your bag before you enter lab.

Mandatory On-Line Safety Training.

1. You should have received an email from the UTA Compliance Department. Click on the link in the

    email.

    2. Log on using your network log-on ID and password (what you use to access email). If you do not know

    your NetID or need to reset your password, visit http://oit.uta.edu/cs/accounts/student/netid/netid.html.

    3. The available courses for completion will be listed. For Organic Chemistry, complete the course

    entitled „Student Lab Safety Training.‟ 4. Go to „Training I‟ve Completed‟, and print this displayed page for your TA. Verify that it shows clearly

    your name, that the training is completed/passed and the date when the training was completed. If you

    have just completed the training but it is not updated on the „Training I‟ve Completed‟ page, try the training

    again (you should get to the Certificate page). If this doesn‟t work, call the Helpline at 817-272-5100.

    5. If you have previously completed the training (since September 2008) then you will not need to repeat

    it but you must still print the „Training I‟ve Completed‟ page for your TA as proof of your training.

    6. If you did not receive the training email and you have not already completed the training you will need

    to contact the Helpline or email compliance@uta.edu.

    7. Students who have not completed the training by census date may be dropped from the lab (and

    consequently the lecture section if enrolled concurrently).

    **All issues with online training should be addressed by calling the Training Helpline at

    817-272-5100 or by emailing compliance@uta.edu.

Notebook: A hard-bound notebook (not spiral-bound) is required. The notebook should be kept in ink.

    The pages should be numbered sequentially, and there must be a table of contents at the beginning. Each

    experiment must include the date the work is done, a title, and a main equation or object of the experiment.

THE FOLLOWING ITEMS SHOULD BE WRITTEN IN THE NOTEBOOK BEFORE COMING TO

    THE LAB

    1. Title of the experiment and date.

    2. Balanced equation(s) for any reactions.

    3. Data for all reactants: molecular weights, moles and grams/volume used, physical constants and

    calculation of limiting reagent.

    4. Sketch and names of apparatus used in experiment.

    5. OUTLINE THE EXPERIMENT IN SUFFICIENT DETAIL THAT THE EXPERIMENT CAN BE

    CONDUCTED WITHOUT YOUR LAB TEXT. Carefully note items related to safety. Include a

    separation scheme for work-up of the product where appropriate. Each experiment must be conducted

    from the outline you have written in your notebook.

    6. Calculate the theoretical yield of your product (show calculations).

    7. Answer assigned questions.

    DURING THE LAB:

    8. Record what you do and observe during the experiment. Weights are to be recorded using the Tare +

    compound - Tare=weight, unless you use an automatic tare. If using an automatic Tare, record this in your

    notebook. The boiling point or melting point range is to be recorded. AFTER THE LAB

    9. Calculate the percent yield (show all calculations).

    10. Conclusion: Comment about or discuss any part of the experiment you think appropriate (e.g., an

    explanation of why the yield is too low, a suggestion for improving some part of the experiment, etc.).

This format may deviate in some details from that given in Chap. 1 of your text. When there are differences,

    please use the format in this syllabus rather than that in the text.

A SHORT QUIZ WILL BE GIVEN ON EACH EXPERIMENT AND ASSOCIATED TECHNIQUES

    PRIOR TO THE BRIEFING FOR THE EXPERIMENT. PRE-LAB EXERCISES MUST BE FINISHED AND STAPLED IN YOUR NOTEBOOK BEFORE YOU BEGIN THE

    EXPERIMENT.

Notebooks will be taken up for grading (unannounced) two or three times during the semester. Your

    notebooks will also be examined by the TAs periodically to insure you are complying with 1-7 above.

Grading: Practical I (15%), Practical II (15%), Unknowns (15%), Other Experiments (15%), Notebook

    (Pre-lab Exercises are 25% of the notebook grade) (15%), Quizzes (10%), Final Exam (15%). Course

    grades: 90% or >-A, 89-80%-B, 79-70%-C, 69-60%-D, <60%-F.

Make-ups are allowed only for practicals and only for students who have a verified excused absence.

    Make-ups are not allowed for non-practical experiments. If a non-practical is missed, there is a deduction

    of 10% of the 15% designated for other experiments. Missing more than one experiment of either type

    will result in an incomplete or failing grade in the course.

    Repeats of practicals: only one practical may be repeated. The repeat and make-up will be given on thndMonday July 6. You must apply for this with your TA, and with Dr. Cleaver, (114 CPB) prior to July 2

    in order to have it scheduled. There will be a 15 point deduction for any practical that is started over or

    repeated.

All equipment on temporary loan from the Stockroom must be returned the same day it is checked out.

    Note: If you decide to drop or stop attending the lab, YOU need to:

    a. Contact the Chemistry Stockroom, 112 CPB, to check out on or before the scheduled check-out date.

    b. See your advisor to drop the class.

Students must check-out on the assigned day, unless they have a legitimate, verifiable excuse. Students

    failing to check-out on the assigned day will receive a point penalty of 10% of the 15% allotted for other

    experiments. If check-out is still not complete one week after the assigned date, the stockroom will check

    out the student and assess a $30 check-out fee, a $30 key fee, and the cost of any broken, missing or

    excessively dirty glassware.

All fees are non-refundable once they have been billed.

UTA will bill your account and it will have to be paid before you will be allowed to register for the

    next semester. This will show up on your tuition bill as “chemical breakage.”

Students with Disabilities: Students who need an accommodation based on disability should arrange to

    meet with the laboratory coordinator in his office during the first week of the semester to see that they are

    appropriately accommodated.

Students who are Pregnant: For students who are pregnant, it is recommended by the Chemistry and

    Biochemistry Dept. that you do not enroll into a chemistry lab at this time. If you become pregnant during

    the semester, we recommend dropping the course as soon as possible; and special provisions will be made

    to assist you in finishing the course at a later date. Please see your faculty instructor for assistance.

Academic dishonesty: UTA considers academic dishonesty a completely unacceptable mode of conduct,

    and the University will not tolerate it in any form. Academic dishonesty includes (but is not limited to)

    cheating, falsification of data, plagiarism, and contracting/collusion with others to do your test or do your

    work. Cheating is the use or acquisition of information (data, constants, formulas, textual material, etc.)

    from either unauthorized sources or in an unauthorized manner. Examples include but are not limited to

    a) exchanging information during a test or quiz.

b) looking at another student‟s paper during a test or quiz.

    c) bringing information in any form into a test or quiz other than personal knowledge. This includes

    written notes (crib sheets) and digitally stored information (formulas, constants, textual, etc.)

    d) looking at a book or any other unauthorized source during the test or quiz.

    e) accessing information by any electronic means (cellular phones, pages, personal stereos, etc.) None of

    these items are to be brought into examinations. f) processing data or information in an unauthorized manner using a programmable calculator or

    computer.

    In other words, unless you have received authorization, you are not to use any computer program. This

    includes specialty computer or calculators in which the programming is “built in” to the computer. You are

    permitted to use simple calculators which perform arithmetical, logarithmic, and trigonometric functions.

In the event that a test proctor determines that a student is cheating, the following actions will be taken:

    1) the student will be notified and, if the situation merits, asked to explain his/her actions.

    2) the source of the unauthorized information will be removed during the remainder of the test period and

    returned to the student following the test, if appropriate.

    3) the student may be removed to a different location to complete the test.

    4) calculator/computer memory will be cleared of the stored information and programs as appropriate. In

    some cases the proctor will need to temporarily examine the calculator to verify unauthorized use. The

    calculator will be returned to the student to finish the test.

    5) a record of the events and actions surrounding the alleged act of cheating will be submitted to the

    Associate Vice Provost for Student Affairs for further action. See Undergraduate Catalog for further

    information.

Following is a statement from the University policy on cheating. “Students who violate University rules on

    scholastic dishonesty are subject to disciplinary penalties, including the possibility of failure in the course

    and dismissal from the University.”
