COURSE DESCRIPTION: Application of techniques learned in CH 317L to carry out synthesis. Modification or introduction of functional groups in a given substrate.

FACILITATOR�S EDUCATIONAL PHILOSOPHY: My main objective is to transfer adequate and sufficient amount of knowledge to all the students at the appropriate levels: a) make sure that students understand the idea I am trying to convey, b) prepare students for the next level of education, c) develop the understanding of students, such that they adapt the process of thinking rather than memorizing facts and principles, d) develop practical skills and techniques to work confidently in laboratories, e) demonstrate how chemistry is part of their daily lives, and f) to use alternative and diverse methods of teaching to keep students motivated and interested during the course of their study in the semester, and hopefully for the rest of their lives.

COURSE OBJECTIVES:

1. To practically learn some, or all, spectroscopic analysis (NMR, UV-Vis, IR, GC-MS etc) of organic compounds using the instruments available in the laboratory.
2. To learn the techniques involved in synthetic process of organic chemistry.
3. To synthesize and manipulate molecules from one functional group to another using the synthesis and reactions learned in CH318.
4. To learn how to write a good lab report.
5. To carry out qualitative analysis of organic compounds.
6. To connect the information learned (chromatography, distillation, crystallizations etc) in CH317L to CH318L.


COURSE ASSESSMENT

Quizzes: there will be a quiz given during every lab session.

Class participation and Attendance: this will include tardiness in coming to the lab, tardiness in submitting lab notebook, absent in the lab without an excuse etc. You are advised to attend all classes. Two weeks of consecutive absences will lead to administrative withdrawal from the class. Attendance is part of your class participation grade

Lab technique: You are required to have presence of mind while working in the lab. You will be graded on how well you receive instructions, cleanliness of bench space, presence of mind, common sense etc. This semester you will be graded on lab technique.

Lab notebook: This should be a hard cover notebook (or the continuation of the book you have from CH317). Try obtaining one that has page numbers in it so you don't have to number each page. Lab notebook is an integral part of any laboratory. It should be kept neat and updated.

Few guidelines

1) number all pages
2) leave a few pages in the front for table of contents
3) write only on the right hand side of the notebook
4) always write in third person past tense (e.g. The melting point was found to be.... rather than " I took the melting point and .....)

5) if you make a mistake just draw a line through it rather than painting it black.

6) lab notebooks should be brought to each lab and written as the lab proceeds rather than writing the procedure at home.

Your lab notebook will be graded on the following points:

1) completion of lab experiment data ie the title, materials, procedure, calculations, conclusion etc.

2) mention of all the points during the lab procedure (including any changes you might have made)

3) after the third experiment points will be taken off for grammar.

4) make sure the spelling of technical words and compounds is correct

Product: In cases where you will submit the product the grading will be done on the basis of the following points:

1) dryness of the product
2) color of the product
3) cleanliness of the product
4) how clean the sample container is
5) data on the product (melting/boiling point, percent yield etc.)


GRADING PLAN

70% Lab reports

10% Products

10% Quizzes

10% Technique: includes tidiness of lab reports, tidiness in turning in samples (if required), general tidiness and presence of mind while working in the lab.

A 90 and above
B 75 -  89
C 60 -74
D 50 - 59
F 49 and below

ACADEMIC HONESTY: Academic Honesty is required of all members of a learning community. Hence, Park will not tolerate cheating or plagiarism on tests, examinations, papers, or other course assignments. Learners who engage in such dishonesty may be given failing grades or expelled from Park.

PLAGIARISM: Plagiarism�the appropriation or imitation of the language or ideas of another person and presenting them as one�s original work�sometimes occurs through carelessness or ignorance. Learners who are uncertain about proper documentation of sources should consult their facilitator.

ATTENDANCE POLICY: Facilitators are required to keep attendance records and report absences. The facilitator may excuse absences for cogent reasons, but missed work must be made up within the semester/term of enrollment. Work missed through unexcused absences must also be made up within the semester/term of enrollment, but unexcused absences may carry further penalties. In the event of two consecutive weeks of unexcused absences in a semester/term of enrollment, the learner will be administratively withdrawn, resulting in a grade of �F�. An Incomplete grade will not be issued to learners who have unexcused or excessive absences recorded for a course. Learners receiving Military Tuition Assistance (TA) or Veterans Administration (VA) educational benefits must not exceed three unexcused absences in the semester/term of enrollment. Excessive absences will be reported to the appropriate agency and may result in a monetary penalty to the learner. Reports of a F grade (attendance or academic) resulting from excessive absence for learners receiving financial assistance from agencies not mentioned above will be reported to the appropriate agency.

Please Note: Attendance is part of your grade. Unexcused absences:
Of 2 labs will result in 3% deduction of overall grade
Of 4 labs will result in a F in the class

DISABILITY GUIDELINES: Park University is committed to meeting the needs of all learners that meet the criteria for special assistance. These guidelines are designed to supply directions to learners concerning the information necessary to accomplish this goal. It is Park University�s policy to comply fully with federal and state law, including Section 504 of the Rehabilitation Act of 1973 and the American with Disabilities Act of 1990, regarding learners with disabilities and, to the extent of any inconsistency between these guidelines and federal and/or state law, the provisions of the law will apply. Additional information concerning Park University�s policies and procedures related to disability can be found on the Park University web page: www.park.edu/disability.

LATE SUBMISSION OF COURSE MATERIALS:

1) Lab quizzes and labs cannot be made up.
2) Lab assignments submitted after one week will not be accepted for grading.


CLASSROOM RULES OF CONDUCT

CAUTION: We will be dealing with chemical compounds during the course hence the following are mandatory for the whole semester

THE FOLLOWING ARE TO BE OBSERVED DURING ALL LAB CLASSES

You must always wear goggles in the lab. (Glasses are insufficient for organic labs).
Absolutely no eating, drinking or smoking in the lab.
You should consider taking the lab another time if you are pregnant.
No shorts or short skirts in the lab.
Always wear shoes in the lab.
PUNCTUALITY IS A MUST. All lab instructions are given during the first few minutes of class, hence if you miss those you will either not know what to do or you will disturb your colleagues.

You will not be allowed to do the lab if any of the above are not followed.

Working in the lab:

  • Everyone is expected to be cautious and take their work seriously in the lab.
  • There should be no pranks or running around in the lab.
  • It is always better to look around and move, you may be safe yourself but you might hurt your neighbor.
  • Always call the instructor to your bench, do not carry around samples around unless instructed.
  • Punctuality in the lab : Most instructions and safety precautions for the lab are given in the beginning of the lab session hence it is mandatory that everyone be punctual to the lab. Anyone late by 5 mins might consider not coming to the lab at all that day. The door of the laboratory will be closed after the first five minutes of the lab session.

Additional Cautions:

  • You are encouraged to attend all labs - simply because no credit will be given for the lab that is missed or report not turned in - i.e. no makeup labs will be given.
  • Each lab is linked with the other in terms of techniques in an organic lab. You might lag behind in techniques if you miss any lab.
  • One experiment may require two lab days ie a total of 4 hours. Hence if you miss the first part of the experiment consider the whole lab as missed.
