Office Hours: M, W: 11:00-12:00 am; T, R: 10:00 am-11:00 noon and by appointment. Office hours are subject to change or cancellation without prior announcement.

Course Content: Chapters 1-14 of McMurry, see following.

Course Policies:

Exams: 3 seventy-five minute exams (100 points each)

1 two-hour final exam (150 points)

The final grades will be determined as follows:

Three Exams (67% of final grade)

Two-hour final Exam (33% of final grade)

Grades: 90-100= A range; 80-89= B range; 70-79= C range; 60-69= D range; below 60= F

Exam dates are indicated on the accompanying schedule and will NOT be changed.

Final Exam: The final exam date is Sat. Dec. 21 at 9:00-11:00 am in room SC 4309. There will be NO alternative date offered. Please make your travel plans accordingly.

Make Up Exams: I will give make-up exams under the following conditions:

1. If it can be made up before the next scheduled class period.
2. If it is arranged prior to the day of the missed exam.
3. There is a legitimate medical or family excuse. These excuses must be verified in writing by the Dean's office for family reasons or a physician for illness. A note stating that you visited Student Health is not sufficient. Having other exams on the same day nor anxiety attacks will not be considered.

If all three of these condition cannot be met and you have an excusable absence from the exam then your final exam will count for a proportionally larger portion of the total grade. It is to your advantage to take all exams.

A note on partial credit: Simply writing down an answer does not entitle you to partial credit. The answer must first be at least partially correct; second, it must be relevant to the question being asked. Writing down the answer to a question that is not being asked does not warrant partial credit.

Honor Pledge: You must legibly write the Vanderbilt Honor Pledge on every exam. Writing the honor pledge acknowledges that you are committed to it. Exams which do not have the honor pledge will not be graded and you will receive a zero.

A Helpful Hint: There is a tremendous volume of information to be covered in this course and we will need to proceed at a brisk pace. I suggest that you come to class prepared, having already read the chapter. This will allow you to concentrate on concepts that may be unclear to you. Chemistry is a problem solving oriented subject, thus I suggest that you try every problem in the chapters we cover ( you may see some of them reappear on exams). Finally, come to class !! Important concepts, i.e. thing that may appear on exams, are emphasized in lecture as well as things not covered in the book. This course is challenging; be prepared to dedicate at least 2 hours per night (10 hrs/wk) on organic chemistry.

Letters of Recommendation: I am willing to write you a honest letters of recommendation. Request for letters should be made to me preferably one month before they are due. Requests for letters for early admissions to Vanderbilt Medical School must be made before Spring Break.

Review from General Chemistry: It is assumed that you have mastered the material taught in General Chemistry. In particular, please review the following topics.

Text: "Chemistry: Science of Change", 3rd ed.; Oxtoby, Freeman & Block
Saunders College Publishing: 1998

Electronic Structure Chapter:17-1
Chemical Bonds 17-4 through 17-6
VSEPR 3-6
Atomic Orbitals 16-5
Molecular Orbitals 18-1 through 18-5
Lewis Structure 3-4, 3-5
Chemical Equilibrium 7-1, 7-2, 7-5
Acid-Base Equilibrium 8-1 through 8-4
Thermochemistry 10-2 through 10-5, 11-5 through 11-8

As the course progresses there will be some important numbers and equations you will be expected to commit to memory. These will be explicitly pointed out to you. You should already know the following from General Chemistry.

The Gas Law Constant, R= 1.99 cals/(mol)(°K) (2.0 is close enough) -or- = 8.314 J/(mol)(°K)

Gibb's Free Energy: DG°= DH° - TDS°

DG°= -RT ln Keq

pKa= - log Ka

In addition, it is also assumed that you know the vocabulary of General Chemistry. That is, you should know the names, structures and charges of the common anions (see Table 3-2, pg. 84 of Oxtoby, Freeman& Block) and the names and structures of common mineral acids (see Table 4-2, pg. 138 of Oxtoby, Freeman& Block) and bases.
