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. 

 

REQUIRED MATERIAL

* “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

October 11, 2007 is the last day to withdraw from the lab without penalty. Before that deadline, a student who withdraws from the lab will receive a “W” grade.  After the deadline, withdrawing from the class will result in a “WF” grade. Departure from this policy will have to be justified before and approved by the Chairman of the Science & Math Division. See page 56 of the ABAC catalog, 2007 for more information. Even though receiving a W has no negative effect on your grade, be aware that withdrawing from a class may impact negatively your eligibility for financial aid.

 

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.
