Grading Criteria:
Quizzes and Assignments  150 points   20%
Exams  200 points   27%
Laboratory  150 points  20%
Research Paper and Presentation  100 points   13% 
Final Exam  150 points   20% 
750 points  100%
Exams:  There will be two exams administered during the lab period on the following dates:
Thursday, February 18 and Thursday, April 1.  The final exam will be administered on the day and time assigned by the registrar.

Assignments:  A portion of your grade will be based on in-class and take-home assignments.  Be aware that in accordance with the College's policy on academic honesty, any work you turn in must be your own.  Any instances of plagiarism (including copying answers from a classmate) will be penalized severely.  All take-home assignments are due at the beginning of the class period.  Late homework will not be accepted.

Reading Assignments:  Readings from the text and chemical literature will be assigned on a regular basis.  You should complete these assignments in a timely manner as they will form the basis of our in-class discussions.  Please be aware that ten points of the quiz and assignment grade is based on participation in class discussions.

Research Paper and Presentation:   You will research and write a 10-page paper on an organometallic chemistry topic of your choice.  During the last week of the semester, you will give a 15-20 minute presentation on your topic to the class.  One lab meeting will be set aside for students to give practice talks with one or two other students and the instructor present.

  Timeline:    Topic due:  January 29
                    References and Outline due:  February 15
                    First Draft due:  March 12
                    Peer Review of first draft due:  March 17
                    Report due:  March 29
                    Practice Talks:  April 15
                    Presentations to Class:  April 21, 22, 23
Extra Credit:  Extra credit points (3) can be earned by attending departmental colloquia.  Any extra credit points earned will be used to nullify unexcused absences from class (see below) before they will be applied to one's grade.  Extra credit is limited to 20 points.
Attendance:  Regular attendance at lecture and laboratory sections is expected, and repeated, unexcused absences will be penalized (3 points per absence).  Attendance at quizzes, exams and laboratory meetings is mandatory.  Make-ups are not  permitted unless the absence has prior approval by me (usually a case of medical or family emergency which can be documented).  A single, cumulative make-up exam will be administered at the end of the semester.  Quizzes cannot be made-up.  In case of an emergency, I can also be reached at my home: 327-2888.

Course Outline:   See attached pages.

Laboratory:   The lab portion of the course is composed of five experiments and one exercise to develop techniques for handling air sensitive chemicals.  Lab reports will follow the format of a JACS or JOC article and will include the following sections:  Introduction and background, results and discussion, experimental, and references.   Additional information on writing reports will be given in class.

Lab Safety:  Unsafe behavior in the lab will not be tolerated and violations will be penalized.  Repeated violations during a class may result in a zero for that lab.  Keep in mind that lab safety includes laboratory hygiene.  In the event that common areas are left dirty, (rotovaps, balances, melting point apparati, reagent hood) points may be deducted from the entire class.  If you have any questions regarding lab safety, please do not hesitate to ask.
