You will find that a set of molecular models will be very helpful when learning to visualize the three dimensional aspects of organic structures. The Molecular Visions Kit 1A is available in the bookstore.
By the end of this course it is expected that the student will:
- Understand and be able to make predictions using structure-property relationships for organic compounds.
- Recognize conformers, constitutional isomers and stereoisomers and be able to determine their relative stabilities.
- Recognize and name compounds containing the important functional groups.
- Recognize the type of bonding involved in any molecule.
- Understand resonance structures and be able to utilize them to explain relative stability of compounds, intermediates, and transition states.
- Understand and be able to use the mechanisms of nucleophilic substitution and elimination reactions to predict which product(s) will be formed, predict relative reaction rates, and predict the conditions that would cause the desired product to be the predominant one.
- Understand and be able to use the mechanism of the electrophilic addition reaction to predict which product(s) will be formed, predict relative reaction rates, and predict the conditions that would cause the desired product to be the predominant one.
- Be able to combine reactions in such a way as to develop a reasonable synthetic approach to a target compound.
Quizzes: After the first week there will be a five minute quiz at the beginning of EVERY class period except exam days. This means that there will be 24 quizzes this semester. Quizzes will typically cover what you were supposed to learn during the previous class period. Quizzes the day after an exam will typically be the one or two most frequently missed questions from the exam.
Exams: There will be three hour exams. All exams are comprehensive and cover everything from the first day of the course up to the class period before the exam. Make-up exams will only be given for university excused absences as defined in the catalog.
Final Exam: The final exam will be the morning of Saturday, December 8, 2007. It will be comprehensive over the entire course and will be roughly double the length of the hour exams.
Computer Based Homework: There will be 14 computer graded homework sets. In most cases these will be administered through the WebAssign system but part or all of some sets will be administered through Vista. You will be able to redo the homework sets as many times as you like. You must score at least 75% on a given set or you will not receive credit for that set.
Calculation of Overall Average: The four lowest quiz scores will be dropped from the calculation. The average of the remaining quizzes will count the same as an hour exam.
The overall average will be calculated by two methods and the higher result will be used in determining the course grade.
Method 1. The quiz average, each hour exam score, and the final exam score will be added together and the total will be divided by 5. Thus, each exam counts 20%, the quizzes count 20%, and the final counts 20%.
Method 2. The lowest exam score is dropped from the calculation. The final exam counts double. The quiz average, the two best exams scores, and double the final exam score will be added together and the total will be divided by 5. Thus the quizzes count 20%, the final counts 40%, and the two best exam scores each count 20%.
Bonus/Penalty: An adjustment will be made to the final average based on the computer based homework. The amount of the adjustment will be (number of homework sets with score of 75% or better – one half of total number of homework sets assigned) time 0.2%. Since we will have 14 homework sets you will be able to earn a bonus of up to 1.4% on your average but you could also get a penalty of up to 1.4% if you fail to do the homework sets.
Grading Scale: Once the overall average has been calculated the course grade will be assigned on the basis of:90 or better = A
80-89 = B
70-79 = C
60-69 = D
59 or less = F
Three Strike Rule
Effective January 2005 the Chemistry department has a policy (one that has been approved by the University Curriculum Committee and the Faculty Senate) that no one may take CHM 355 a third time unless they have successfully completed CHM 254. A withdrawal counts as an attempt. No student will be permitted more than two attempts to pass CHM 254.
This policy includes a “three strike” rule for CHM 355. After successful completion of CHM 254 the student will be given one final chance at CHM 355 but no one will be allowed more than three total attempts at CHM 355 at Marshall University.
The Vista web server has a link for this course for all students registered for the course. The Vista page for this course will serve as a very important communications link between the students and the professor. The Vista page will be used to post answers to text book problems and to make announcements to the class. We may also use this resource as a way of encouraging group study.
You should check the Vista page daily for new announcements and course related information. To get to the Vista page you should use your computer browser to go to http://vista.marshall.edu. You will log in using your student ID number (the one that starts with 901) and the same PIN number you use for myMU and MILO. Once you are logged in you will see a link for all of your classes that have a Vista page. Click on a course and you will be taken to the materials for that course.
By far the best way to contact the professor is to either use regular internet email and send a message to email@example.com or use the mail facility within the Vista page to send a message. The instructor is listed as Anderson, Gary fairly near the top of the list. If you use internet mail, be sure to put CHM 355 in your subject line so that I will know the message is from a student in my class and thus can give it priority over all the other email messages I get.
If you try to call me, I will answer the phone if I am in my office but if I am not in you will get the voice mail system. If you leave a message you should be sure to leave full information about how to get back to you (include the area code with your phone number). My policy is that I will make one attempt to return your call but if I don’t get through on that attempt I will not make any further attempts.
Students are expected to attend all classes. A large part of the learning process in this course is based on the in-class activities. If you are not here you will not have a chance to participate in those activities.
There will be no makeup quizzes – if you miss a quiz it will simply be one of the four that is dropped from the calculation. If you miss a class it is your responsibility to get class notes from another student in the class.
During exams you may not use your own paper or other materials except your pen or pencil and a set of molecular models.
Academic dishonesty will not be tolerated. Academic dishonesty includes unauthorized use of any materials, notes, sources of information, or study aids or tools during a quiz or exam. It also includes the unauthorized assistance of any person other that the course instructor during a quiz or exam, the unauthorized viewing of another person’s work during a quiz or exam, or the unauthorized securing of all or part of any quiz or exam before submission by the instructor.
The minimum penalty for academic dishonesty will be a failing grade for the course.
I do not have any objection to students taping my lectures but I doubt that it will help very much because the taped lecture will not be very meaningful without the blackboard materials that go with it.
Cell phones, pagers, and the like must be turned off before entering the classroom. Failure to comply with this can result in you being removed from the classroom, even during an exam.
Students requiring accommodation because of a disability must obtain appropriate documentation (from the Help Center or Sandra Clements) and contact me at least one week in advance of each test so that necessary accommodation can be made.
Working problems is an essential part of the process of studying organic chemistry. You should work all the problems that are within the text material since these are designed to allow testing yourself on understanding oft he section(s) just before these problems. The answers to these problems are in the back of your text book.
You should work all of the Exercises at the end of each ChemActivity in the Straumanis workbook. I will be posting the answers to these in the Vista course supplement.
You should also try to work most, if not all, of the problems at the ends of chapters in the Hornback text. This is time-consuming, but it will be of great benefit since the major objective of the course is learning to solve various types of problems. I have listed selected problems in the schedule portion of this syllabus. Even if you can’t find time to work all of the end of chapter problems you should, at a minimum, work at least those on this list. Answers to the selected problems will be posted in the Vista course supplement.
