CHEMISTRY 350 FALL 2009 Professor: John Bartmess Office: BU 601 | Phone: 974-6578 | Email: bartmess@utk.edu Class time and location: BU 300, MWF 9:05-9:55 AM NOTE: I have a very aggressive junk mail filter. If you email me, please include "Chem 350" in the subject, so my junk mail filter doesn't kill it. Blackboard: I will use both the email function and links to documents in the Blackboard system this semester. It is your responsibility to either routinely read your "formal" @utk.edu/@tennessee.edu email account, or to have it forwarded to an account that you do check. Because providers like Yahoo/ Hotmail/ Gmail do not generate bounce messages when mailboxes are full, I have no idea if you are getting things or not if your email is set up that way. You are responsible for email sent to your @utk address. Office Hours: Wed 1:30-2:30 PM, Thu 1:00-2:00 PM. I'm also glad to make appointments at the end of the lecture period for discussions at whatever time. However, the 30 minutes before the lecture are NEVER available times, due to my reviewing for the lecture. NOTE: I am also teaching Chem 360 MWF 11:15-12:05, and thus may be busy with those students during office hours. When you come into my office, please let me know which class you are in. Obviously, I am not available for appointments at that hour, or just before it, either. Hour Exams: 21 Sept (Mon){class 14}, 12 Oct (Mon){class 23}, 16 Nov(Mon){class 37} Your worst one of these three (relative to the class average on that exam) counts 15%, and the two others count 22.5% each, of the course points. Based on the rate at which the material is being covered, these may be moved slightly later; they will not be moved earlier. Check in class to be sure of the dates. Answer keys will be posted in the glass-front cabinets outside the rear door to BU 415. I will typically have a Question & Answer session sometime the day before each exam. Final Exam: 7 Dec (Mon) 8:00-10:00 AM. 40% of total points. Cumulative in content. Text: “Organic Chemistry,” 7th. Ed., Carey. Required. “Student Solutions Manual,” Atkins and Carey (recommended) This is not just the answers to problems, but a wealth of material that will help you learn. Read! “Proteus Organic Model Kit" (recommended, though splitting one set with another student is okay) - available from Student Affiliates of the American Chemical Society, outside BU 415, 1st full week of classes. "Framework Molecular Models" are also acceptable. Chapters 1-11 will be covered this semester, with a few sections omitted (see below) The selected problems will not be collected or graded, but will be considered fair game for exams (though not exclusively so). Background: I expect you to have a reasonable knowledge of certain topics (see below) from General Chemistry, including equilibrium, acidity (pKa and pH), reaction coordinates, etc. I will announce when I am assuming some such knowledge and will refer you to certain sections of the General Chemistry text, so that you can review it if you need to. See below for a further list. Rules for missed exams: If you miss an exam, you must have a valid, verifiable excuse, presented to me within 24 hours. For an hour exam, if the excuse is accepted, your grade for that exam will be assigned based on your performance on the other hour exams, relative to the class average. If the excuse is not accepted, you will be assigned a zero on that exam. You cannot miss two hour exams and get credit for the course. If you are failing the course coming into the final, and you miss the final (even with a valid excuse), a grade of "F" will be assigned. Exam Regrading: Arithmetic mistakes of addition or transferring points to the front page will be corrected anytime. For regrading of an answer's content, the exam must be submitted no later than three class meetings after the exam date, with the number of the question(s) to be regraded clearly marked on the front. Also, you need the feedback from how you did on a previous exam, to help you study for the next exam. If you don't pick up your previous exam by three class meetings after the exam, I won't return your next exam until you come in to see me during office hours. Class Attendance. This is not a course that you can pass solely by reading the book. I expect attendance at all classes, though I do assume that you are responsible adults, and thus I will not take attendance. I will sometimes make announcements in class regarding material to be covered, or exam content, or so forth, that you will be responsible for knowing. An excuse of “I didn’t know” is not acceptable. Snow policy: If UTK is officially closed due to weather at the hour of an exam, the exam will be given at the next class meeting. If UTK is open, but weather keeps you from attending, contact me that day to explain your problem. University Rules (Undergraduate Catalog, p. 44) - A passing grade in both Chem 120 and Chem 130 is a pre-requisite for taking Chem 350. If you have not done this, there's no point in taking 350; I'll have you adminstratively dropped from the class. Yes, I do get a summary statement from the Registrar about people with registration problems like this. - You are not allowed to take a course more than three times. If you have taken Chem 350 three times already and received an assigned grade (including WP/WF), you cannot take it again for credit at UTK. - You cannot repeat a course for credit in which you have received a grade of "C" or better. - I will use the new minus grades, as well as plus ones. Disability Services Statement: Students who have a disability that require accommodation(s) should make an appointment with the Office of Disability Services (974-6087) to schedule an appointment to discuss their specific needs. WP/WF Rules: At the time you apply for a WP/WF withdrawal, if the sum of your exam points is less than 2/3 of the summed class average on the exams given up to that time, the grade will be WF. This cutoff is not negotiable. Future letters of reference: I do not do "cold" letters of reference, based on a single future meeting with someone. If I don't get to know you somewhat, through your visiting me in my office with questions this semester, I will decline to write a medical/dental/pharmacy reference letter in the future. Problems in the Text: There are two kinds of problems in the text. - "Study Problems" have the answers right after the problem. It is to your considerable advantage to cover that answer and work the problem in writing first. - There are "regular" problems throughout each Chapter and continuing at the end. The answers to these are in the Solutions manual. The assigned problems listed below come from these "regular" problems. Prerequisites for Chemistry 350: Successful completion of General Chemistry 120+130 or their equivalents. In our 120+130 sequence we cover the topics and terms listed below. It is expected that you will come to Chem 350 with a working knowledge of these topics and terms. If you are not familiar with any of these, you should review them in a general chemistry text.
