Required text

• "Organic Chemistry",Third Edition, by Paula Bruice: Prentice Hall Publishing, 2001. (The same text as was used in the first semester.)
• The Study Guide and Solutions Manual for this text.

Course Philosophy

This course strongly accentuates reaction mechanisms and theoretical understanding of organic chemical reactions. On exams, mechanisms must be written out exactly (for full credit), with rate-determining steps specified as "rds" or slow steps as "slow" over the reaction arrows. The student should be able to rationalize why the appropriate step is rate determining or slow, also. All steps known to be equilibria ( as mentioned in class) must be so indicated by the use of equilibrium arrows. Theoretical explanations of structure, rate, specificity, etc. must be logical and complete to the level expounded by the instructor in class. Great emphasis is placed upon the specific material discussed in the lecture, understood at the level at which it is presented and demonstrated appropriately on the exams..

Transition state models are often required and must be derived from resonance theory, not simply written down as dotted line/partial charge structures. Transition states are characterized by various characteristics such as carbocation or radical or alkene character and often this must be refined to a more specific sub-character, such as primary or secondary or tertiary carbocation character or arenium ion character or monosubstituted or disubstituted alkene character. The characterization is then extended by the use of the Hammond postulate, whenever it is applicable, to indicate whether the transition state has much or a little of the specified character. It will usually be necessary to explain the specific application of the Hammond postulate and how it is being applied.

The Method of Competing Transition States must be used in many cases to explain the results of competing reactions such as orientation in electrophilic aromatic substitution, or relative rates, or reaction specificity.

Exams

• Exam 2:Wednesday
• Exam 3:Wednesday
• Final Exam: Saturday

Grading system

• Each exam counts 100 points; the final exam counts 150, for a total of 450 possible points. Homework does not contribute to the grade.
• Exam papers, except for the final exam, will be handed back in class. The answer keys to exams are typically posted on a bullitin board near the room where our class meets.
• Regrade requests must be handed in within one week of the day on which the exam paper is returned. The right of regrading the entire exam is reserved. Our standard procedure must be followed. This consists of attaching a cover sheet to the exam in question which specifies which questions and answers are at issue and why, as succinctly as possible. The exam with the attached cover sheet is brought to the lecture and given to the TA . Regraded exams will be returned in the same way, i.e.at class time.
• At the time that each exam paper is returned, an orientational curve will be presented. These are not intended to represent formal letter grades, but only an approximate indication of your standing with respect to the class. The final course grade will be curved, but the student should understand that the A and B ranges will still be approximately in the 90's and 80's, respectively, give or take a few points (most likely one or two). The "C" range usually extends down to about 60 as the lowest "C", and anything below 50 will undoubtedly be failing.
