1. Course Description: Organic Chemistry II (Chem 228) is a chemistry course designed for a variety of
science and engineering majors. It is a continuation of Organic Chemistry I (Chem 227) which is a prerequisite. Concurrent registration in the lab course Chem 238 is highly recommended. Emphasis will
be placed on more advanced aspects of organic chemistry including the reactions of functional groups,
synthesis, spectroscopic methods for identifying organic compounds and reaction mechanisms.
Organic chemistry concepts provide the molecular basis for the fundamental concepts and observations
in many other disciplines, including biology, biochemistry, chemical engineering, genetics,
pharmacology and nutrition.
2. Course Learning Outcomes:
By the end of this course, the students will be able to:
a) Compare and contrast the structures, properties, and reactions of aromatic compounds, aldehydes
and ketones, carboxylic acids and derivatives, carbohydrates, amines, and amino acids.
b) Draw from an appropriate name the structure of simple organic molecules with the above
functional groups including descriptors for stereochemistry (cis/trans, E/Z, R,S).
c) Understand the principles of Mass spectrometry and Nuclear Magnetic Resonance spectroscopy
and to use spectroscopic data to deduce structures of organic molecules.
d) Relate structure to acidic and basic properties and the relationship of such properties to the
reactivity of common functional groups.
e) Use the principles of thermodynamics and kinetics to characterize organic chemical reaction energy
changes, reaction rates, and mechanisms for aromatic compounds, aldehydes and ketones,
carboxylic acids and derivatives, carbohydrates, and amines.
f) Depict reasonable reaction mechanisms using the curved arrow formalism for reactions involved in
the synthesis and transformation of the above functional groups.
g) Predict the outcome of any given set of organic molecules and synthetic reagents involved in
synthesis and reaction of the above functional groups using the basic patterns of reactivity and
reaction principles covered in the text.
h) Design multi-step organic syntheses using the method of retro-synthetic analysis.
i) Solve chemical problems involving the studied functional groups using the basic generalizations
and principles covered in the course and reasoning by deduction and analogy.
j) Explain a variety of applications of organic chemistry in society.

3. Major Text/Electronic Resource: John McMurry, Organic Chemistry, Eighth Edition,
Brooks/Cole Publishing Co., 2012 with PAC for TAMU Organic OWL with e-Book and Electronic
Study Guide. This bundle is available at most Bryan/College Station area bookstores. This bundle
represents a significant savings over purchasing the textbook, study guide and PAC for TAMU Organic
OWL separately. You MUST have the electronic resource package, PAC for TAMU Organic
OWL, since all graded homework will be electronic. Also see “Texbook Info-TAMU Organic
Chemistry and Using OWL at TAMU” on eLearning.
4. Molecular Models: You will find that a set of molecular models is very useful in this course. Any
type is okay, but the Darling Models sold by the student affiliate chapter of the American Chemical
Society at A&M is recommended. These model kits will be sold below retail price. You will find
these models especially useful in dealing with stereochemical relationships and in visualizing the
geometry of certain types of molecules. You will find them useful in the laboratory as well.
5. eCampus: I will be posting course information throughout the semester on eCampus. This will include
past exams, practice problems and other announcements. It is your responsibility to check eCampus
regularly for information updates.
6. Problem Solving: In order to successfully complete this course it is absolutely imperative that the
majority of your study time be spent reading the relevant chapters in McMurray and working
the
suggested problems. They should be faithfully worked on a regular daily basis. Reading and working
lots of problems are sure to result in an improvement of your grade! This advice should not be taken
lightly. Merely scanning the answers provided in the study guide or becoming dependent on the study
guide too quickly serves no useful purpose. It's much more difficult to work a problem than it is to
convince yourself that the solution before your eyes is the correct one. Just ask any previous organic
student who took this course how important working problems is. This is the most crucial factor to
your success or failure in this course!
There is quite a bit of memorization associated with this course. However, memorizing answers
fails to be enough; you must also understand the concepts.
7. Supplemental Instruction: This will serve as an additional resource for you. Attendance at these
sessions is highly recommended. The times and dates for SI sessions will be announced in class by the
SI leader.
8. Office Hours: I will be available in my office during the times I've posted on eLearning. Please
schedule your visits during my office hours. I will try to meet with you at other times if these
times are not possible. You may contact me by email; however, I will not respond to organic
chemistry problems by email. Be prepared to ask specific questions when you attend.

9. Examinations and Quizzes:
a) Major Exams: Exams will cover the material in the text and the lecture material as well as any
other assigned material. There will be 4 major exams of 100 points each. These will contribute a
total of 400 possible points to your course total. There will be no exam scores dropped. Exams will
be 50-55 minutes in length and will be comprehensive but material covered since the previous exam
will be emphasized. You will not be allowed to re-sit exams to improve your grades.
Excused Absences: Makeup examinations for major exams will be given only for Universityexcused absences provided the appropriate documentation is provided within the time frame
specified in Part I: Academic Rules (http://student-rules.tamu.edu). Please note that Student Rule 7
regarding Attendance and Excused Absences has been modified this year. Absences of less than three
days due to injury or illness will require that you provide either a physician’s note affirming the date
and time of visit related to the absence or the newly established TAMU Explanatory Statement for
Absence from Class form available at: http: //shs.tamu.edu/forms.htm.
You may use this form to document excused absences of less than three days if you do not have
a physician’s note but please keep in mind that the information will be verified. Any
misinformation included on the form or an inability to verify the information will lead to
sanctions under the Aggie Code of Honor. Absences of three or more days due to illness or injury
will definitely require a physician’s or other acceptable documentation. Appropriate documentation
will be required for other excused absences. The university policy has an absolute deadline (by the
end of the second working day after the absence) by which you must notify the professor of any
excused absence. I expect you to contact me the day of the examination or before the examination if
you must miss an exam for any reason. Rarely would it be impossible for you, your roommate, a
friend, or parent to contact me during this time frame. Delays in notification usually raise some
doubts about the validity of the excuse. Do not take this admonition lightly since some people
receive zeros on exams each semester for failure to follow this University regulation.
b) Final Exam: A mandatory, comprehensive 200 point, 2 hour, final exam will be given at the
time dictated by the University schedule.
c) Exam Schedule: A tentative, but reasonably accurate, schedule for the 4 major exams is given
below. Changes in major exam dates will be announced at least three days in advance. If you miss
class and do not find out about the changes that is your problem and it is not a valid reason for
requesting a make-up exam.

The dates for the final exams are firmly set by University policy. You must see the
Spring 2014 Final Examination Schedule on the TAMU website to determine the date and
time of the final exam for your section. The last day of class for this section will be on May
5th (Tuesday).
d) OWL Homework: Graded homework assignments will be given in OWL throughout the
semester. OWL assignments will contribute 100pts (14%) towards your course total. OWL
assignments consist of end-of-chapter problems (70pts) and homework pool problems (30pts).
The due dates for the OWL homework will be posted.
10.
Daily Seating and Exam Seating: You will have assigned seats on the days that exams are given.
ID's must be presented upon request at exams or you run the risk of getting a zero if I do not know
who you are. You may sit anywhere you want on other days.
11.
Course Grade: Your course grade will be based on your performance in the OWL assignments,
exams and the final exam. There will be 700 possible points based on the four 100-point hour
exams = 400pts (57%), OWL assignments = 100pts (14%) and the final exam = 200pts (29%).
12.
Cheating: Cheating will not be tolerated. The minimum penalty for cheating will be an
automatic zero on the exam or quiz in question. Suspension from the University may also
result. Don't risk it. It's not worth it. See the Aggie Honor Code.
13.
Exam Regrading: If you have a question concerning the grading of your exam/quiz you may
submit the entire exam/quiz for complete regrading. This is only fair. If you want credit for
questions incorrectly graded in a way that penalized you, you must be willing to accept the fact that
there may have been a question incorrectly graded in your favor. Do not worry that I will seek ways
to take away partial credit or penalize you because you want your exam re-graded. This almost never
happens. I will be fair. The exam must be submitted for regrading by the next class meeting after the
date the exam was returned to the class. Failure to pick up your exam on this day is not an acceptable
excuse for having it re-graded at a later time. Do not write anything on the exam after it is returned
to you if you wish to have it re-graded. Exams upon which corrected answers have been marked will
not be re-graded. After the next class period all grades are considered to be final. Thus, if you
believe that you deserve some partial credit you must take care of this immediately or forfeit
your right to have the issue considered. I will not debate this issue at the time of assignment of
final grades. Some exams may be photocopied at random before they are
returned to the
class to discourage cheating by correcting incorrect answers on graded exams.
14.
Progress: I will attempt to let you know your approximate class rank and approximate letter grade
throughout the semester. In cases where your record of an exam score and mine do not agree, I
consider it your responsibility to bring the matter to my attention at the earliest possible moment and
to show me the complete exam in question. Therefore, do not dispose of your exams/quizzes until
you are convinced your course grade is correct.

Tutors: Be very, very careful if you choose to use a private tutor or one of the "professional"
tutoring services. Anyone can advertise himself or herself as a tutor; even people who made C's and
D's in courses profess to be able to tutor. I suggest that you very carefully interview any tutor as to
his/her background in organic chemistry. Some tutors are very good but even the very best should
not be considered a substitute for lots of hard work on your part. It just doesn't work that way in
organic chemistry! Utilize any resource that helps you learn organic chemistry but do not look
for shortcuts. There aren't any.
17.
General Advice and Comments: I enjoy teaching and am very willing to help you, but I must be
convinced that you are putting in your share of effort. Most of you are probably apprehensive about
his course to some extent and that's good. A little panic is good for you. Too much panic can be
disastrous, however. How can you avoid too much panic? Concentrate on what you do know and
not on what you don't know when you sit down to take the exams. The time to concentrate on what
you don't know is before the exam. The grades will be adjusted to reflect the fact that the exams are

designed to really test your knowledge by providing for a "large spread" on either side of
the median. In general, the grade distribution will be similar to that for the other chemistry 228
sections but could be higher or lower depending on your performance. That is up to you. Some of
you will be very good, some of you will be average, and some of you will have a difficult time with
organic chemistry. Not everyone can make an A or B, but I'm convinced that almost everyone can
pass this course with a C or better if they work hard and keep up. Daily preparation is important!
