GENERAL

Pre-requisites and Co-requisite

A grade of “C-” or better in General Chemistry I and II with lab (CHEM 211/211L and 212R /212LR), or the equivalent courses, is required for enrollment in this course. There is also a co-requisite of CHEM 321 Lecture.

Course objectives

The objectives of this course are to teach basic organic chemistry technique and to provide experiences that will expand and enhance the student’s scientific background.

Pre-lab lectures and announcements

All classes will convene in room C212 in the Spencer Chemistry Building before entering the lab for class announcements, pre-lab lectures, and submission of lab reports. Attendance will be taken in pre-lab.

Required materials

· Mohring et al. Techniques in Organic Chemistry, 2^nd ed.; 2006, W.H. Freeman (ISBN 0-7167-6935-2).

· A lab notebook capable of making carbon copies (100 pages is a good size). The copies are submitted to your GTA as you leave the lab each session and become part of your report; you retain the originals.

· Padlock, safety glasses, black felt-tip pen with permanent ink (Sharpie).

· Non-graphing calculator (like the one you used in General Chemistry I and II).

· Appropriate clothing (i.e., no shorts, open-toed shoes, etc.).

GRADING During the pre-lab lecture, the GTAs will tell you what you need to hand in for your report on that lab. You will turn in nine lab reports, each worth 20 points (the tenth lab is an extended lab report and is worth 30 points). Your lowest lab score (from the twenty point labs) will be dropped (if you have an “excused” lab, it will be your dropped lab), for a total of 190 points for your reports.

Laboratory Performance and Technique:

Part of the grade for each lab report will include a score for laboratory performance and technique. You are expected to be prepared for lab, maintain your drawer, space and wastes appropriately, wear safety goggles/glasses and proper attire at all times while in the lab, and follow all check-in and check-out procedures. You will have points deducted for tardiness, lack of preparation, non-completion of lab or other infractions of safety and good lab practice.

Extended Laboratory Write-Up:

The extended laboratory write-up (tenth lab) will be over the lab called “Substitution Reactions S_N1: triphenylmethanol” and is worth 30 points. The GTAs will tell you what kind of information you need to include in this lab.

Saturday Laboratory Exams:

There are two laboratory exams, each worth 50 points, which will be held on Saturdays. Please mark them in your calendar and bring a calculator.

LAB EXAM 1: OCTOBER 24 (Saturday) from 12:00pm-2:00pm in Royall Hall 111.

LAB EXAM 2: DECEMBER 5 (Saturday) from 12:00pm-2:00pm in Royall Hall 111.

Grading Detail:

Assignment Total

9 Lab Experiments (20 points each) 160

1 Extended Lab Report 30

Lab Exam I 50

Lab Exam II 50

TOTAL POINTS POSSIBLE 290

The total amount of points for this class will be 290 points. Grades will be assigned as follows: 90% and above = A; 89% = A-; 88% = B+; 80 – 87% = B; 79% = B-; 78% = C+; 70 – 77% = C; 69% = C-; 68% = D+; 60 – 67% = D; below 60% = F.

Note: You will lose 1 point on anything that you hand in as a lab report for the first occurrence of the following: a spelling error, grammatical error, and partial sentence. Spell-check and proof-read your typed work. Anything written in pencil will not be graded.

Your lab grades may be checked via Blackboard at Blackboard.umkc.edu. Your Blackboard User ID and Password are the same as your UMKC Exchange/SSO user ID (the alias from your Alias@umkc.edu e-mail address). If you don’t know your Exchange/SSO User ID, you can obtain it at www.umkc.edu/exchange-faq. Lab handouts may also be found on the Blackboard site or at the Chemistry 321L course website http://cas.umkc.edu/chem/chm_courses.htm.

POLICIES Enrollment and Attendance

You must be enrolled in the section you are attending. If you are not enrolled by the end of the second week of classes (September 4^th), you will be asked to leave the lab.

Attendance is required and will be taken by GTAs at all laboratory classes. The class starts on time and finishes on time. Please observe the following:

· Students must attend their assigned laboratory section.

· Only substantial and unavoidable reasons (e.g., serious illness, unavoidable out-of-town professional travel, death in the family, or religious observance) should cause students to miss a regularly scheduled lab. You should not miss a lab simply because your lowest score will be dropped!

· There will be no make-up labs! All of the organic lab sections are completely full. Even if you have an excused absence, you will be unable to make-up the lab you missed. This will be your dropped lab.

Safety and Honesty

During the first week of classes, safety regulations will be reviewed. You are expected to follow them. When in doubt, ask your GTA or lab instructor. Do not, under any circumstances, use fabricated data or data from another student. Fabrication of data is academic misconduct, as is plagiarism, cheating and sabotage: you will receive a grade of zero on the tainted work and will be reported to the Chief Academic Officer of your academic unit. Serious and/or repeat offenders will receive an F grade for the course and face disciplinary action from the University. It is your responsibility to know and uphold the UMKC rules of academic conduct (http://web2.umkc.edu/catalog/Student_Conduct.html).

During the check-in week of the lab, you will be asked to sign a statement that you understand the safety regulations and academic honesty policy, and agree to adhere to them. A copy of these regulations is provided.

Laboratory

You must provide a padlock for your glassware drawer. You are responsible for maintaining the glassware clean and in good condition and for keeping your equipment drawer clean. Even though you are expected to take appropriate care with equipment and glassware, it is reasonable to expect a small amount of breakage. Notify the GTA as soon as possible if something is broken; you will be issued a replacement. No student will receive a grade for the course until he/she has checked out at the end of the semester.

Lab Reports

The due dates for lab reports are listed in the class schedule accompanying the syllabus. Lab reports must be turned in at the beginning of the pre-lab lecture prior to entering the laboratory. Late lab reports will never be accepted. No exceptions will be made.

Regrade and Grievance Policy

Regrade requests for the lab reports should be submitted to the GTA as soon as possible, and no later than within one week of receiving the graded lab report. The GTA may decide to pass certain regrade requests to the instructor. Any other grievances about the class should be first taken up with the instructor. After contact with the instructor, further comments and complaints may be addressed to the Chemistry Department Chair.

LAB NOTEBOOKS

· Read pages 30-33 in Mohrig et al.

· Each experiment should begin on a new page.

· Put your name, your section, your TA’s name on top of every page in every experiment.

· Make every entry in your notebook in ink, never in pencil. Anything in pencil will not be graded. Do not erase or black out entries. Instead, ~~draw a line through the error~~ and add the new information.

· Record all laboratory observations and data directly in the lab notebook at the time they are observed. Do not use scratch paper. Do not expect to transcribe any information into your notebook at a later time. Carbon copies of your notebook entries should be stapled and handed in at the end of every laboratory session. Your typed reports must draw on data and observations recorded in your lab notebook.

· Organize your lab notebook using headings such as Title, Purpose, Procedure, Observations, Apparatus or Glassware set-up, Balanced reaction or Mechanism, and Purification.

· Do not, under any circumstances, use fabricated data or data from another student.

LAB REPORTS

For each experiment you will hand in (1) the carbon copies of pre-lab and data and observations pages from your lab notebook before leaving the lab and (2) a completed lab report on the scheduled due date, before leaving the pre-lab. Your report will consist of these two submissions and a pre-lab quiz, if applicable.

Your lab notes will be hand-written; all other submitted work should be type-written, with the exception of structures and figures, which should be hand-drawn in ink. Anything in pencil will not be graded.

The individual lab handouts will be available for download at the course website and will be up the Monday before the week of that lab.

Before lab Þ Pre-lab

You will need to write in the procedure fully in your lab notebook because the handouts will not be allowed in the lab. You should be thorough enough so that you can perform the experiment from what you have written. Any changes to the lab will be announced in the pre-lab lecture and need to be noted in your lab book. When you arrive in lab, your GTA will sign your notebook pages ensuring that you have completed the required pre-lab. If not, you will not be allowed to start the experiment. You will have to leave the lab, complete the pre-lab, and then return to the lab but all labs will stop by the end of the lab section. No time extensions are allowed.

The pre-lab in your notebook at a minimum should contain the following

· Title

Begin each experiment on a new page with a title, your name, the date, your TA’s name and your lab section.

· Purpose

A brief statement of the experimental objectives

· Net equation and/or mechanism of reaction (for preparative experiments)

Include for all important reactions.

· Table of quantities and physical constants

Collect in tabular form the name, structure, formula, molecular weight, and density of any substance whose mass or volume you must measure (make sure you include units where appropriate!). Some of this information can be found in the handouts. That which is not in the handouts can be looked up in The Aldrich Chemical Company Catalog, The Merck Index, The CRC Handbook of Chemistry and Physics, and on‑line at http://chemfinder.camsoft.com or http://webbook.nist.gov/chemistry or http://www.inchem.org/.

· Theoretical yield (when necessary)

Calculate the theoretical yield of all reactions, showing all calculations.

· Procedure

Provide an outline of the experimental procedure to be carried out. Do not simply copy what is written in the handouts; use your own words and diagrams. It is often useful to construct a flow chart of the procedure.

During lab Þ Data and observations (hand-written in your lab notebook)

Maintaining good experimental records is an essential part of the laboratory work. For all experiments, record what was done, including amounts (in g or mL, and in mol or mmol) of the compounds used, and your observations (i.e., changes in appearance, color, temperature, precipitation, evolution of gas). Also, where applicable, include work-up, isolation, and purification techniques used, isolated yields (in g or mL and in percents), and appearance of the final product (physical state, color, texture, smell).

Carbon copies of these pages will be stapled together and submitted before leaving the lab. Failure to turn in those pages counts as an absence. If an absence for a lab is recorded, a grade of “0” is unavoidable.

After lab Þ Summary of results and lab report (typed; CANNOT be hand-written)

You will receive a list of what is required for that lab during your pre-lab lecture. You will need to type all of the information required. All calculations must be explicitly included and type-written. If your handout includes post-lab questions, type the answers to them in the appropriate space in “Post-lab Report”. Figures, structures and mechanisms are to be hand-drawn in ink (not in pencil). Any work submitted in pencil will not be graded. Your typed reports will be cross-checked against your lab notes. Spell-check and proof-read your typed work (see GRADING).

Your post-lab reports will be collected on the date they are due, in the pre-lab room.

Do NOT submit your lab reports to Chemistry Office!

Statement on Sexual Harassment

Recently there has been considerable media coverage of an alleged case of sexual harassment of a graduate student and an Associate Professor in the College. That case is under active investigation and no findings of fact have yet been made. It is important that we do not jump to conclusions of guilt in cases such as this; nor should we prematurely assume that the allegations are false. The presumption of innocence until proven otherwise is a cornerstone of the American justice system.

Please be assured, though, that the College and the University of Missouri-Kansas City have a zero tolerance policy for sexual harassment, intimidation, or discrimination of any kind. The faculty and the administration are committed to creating and maintaining an environment on campus that is free of all forms of harassment, intimidation, and discrimination.

Should you or a friend ever experience any action or speech that feels coercive or discriminatory, you should report this immediately to the department chair, the office of the Dean, and/or the Affirmative Action Office. The Affirmative Action Office will be responsible for investigating any complaint of discrimination or sexual harassment.

We are a community of learners dedicated to the pursuit of knowledge and the acquisitions of skills that will enable us to lead rich and full lives. We can pursue these ends only in a culture of mutual respect and civility. It is incumbent upon all of us to create a culture of respect everywhere on campus and at all times through our actions and speech. On behalf of the faculty of UMKC, I pledge to you that we will maintain a safe environment on campus that fosters respect for everyone.
