Recommended Problems (0 %):

These questions will help you learn,
understand and practice organic chemistry. These are only
recommended and as such will not be collected nor graded; however,
please do them and bring them to office hours to discuss them. |

Weekly Peer-lead Team Learning
Workshops (8 %)
q
The most effective way for learning
organic chemistry is by doing practice problems in an environment
conducive to learning. As a result, we will have weekly mandatory
Team learning workshops. During this time, students will work on
workshop specific, instructor designed problems in order to develop
a better understanding of how to do organic chemistry. The most
important aspect of the workshop program is for each student to
actively engage in the solving of problems. In order to help
facilitate this, a peer-leader, someone who has successfully
completed the course recently, will help students work together
using various groups and activities to understand and solve the
problems. THIS PERSON WILL NOT PROVIDE THE ANSWERS, but rather will
encourage students to prove it to themselves and her that their
answer is correct. The problems from this workshop will be provided
during the workshop and will not be collected or graded. The
content, however, is appropriate for assessment via exams. This
program (for which we have received funding from the NSF) is a
proven method for helping students learn organic chemistry and
should effectively reduce your workload in the course. If you are
interested in becoming a peer-leader for next year’s organic course,
please let me know by mid April. Times of workshops TBA. |

Problem Sets (16 %):
q
These questions will resemble the type
of questions contained on the exams. The problem sets will be
collected on Wednesday at class time (9:00 am) the week before the
tests. The problems set will be graded based on your overall
understanding of the material in question. As substantial partial
credit will be given, it is extremely important that you show your
work on your homework. In organic, it is more important to think
properly, show proper problem solving skills and present a sound
argument rather than obtaining the "right answer". I would almost
go so far as to say that the answer does not matter and that the
process by which you arrived is the only thing of importance. Never
the less, you must work the problems completely, show your work and
arrive at the desired answer to receive full credit. Some of the
questions will be challenging. I do not expect you to be an expert
on answering questions when you start the class, but I do expect
that you will work hard on these problem sets. If you have
questions, PLEASE ASK. Do not work on these problem sets in a
vacuum or on the night before they are due. |

Literature Assignments (8 %):
q
As organic chemistry is a constantly
growing and changing field, it is important that you learn how to
explore the current scientific literature.
Ž
Literature Assignment 1(Due March 5):
Find an article in an appropriate organic chemistry journal that is
related to a topic we covered in class during the previous three
class periods (see webpage for a list of appropriate journals).
Read the abstract, introduction and conclusions and skim the
article. In a 1 – 3 page paper, write about why the authors
conducted the research, what fundamental questions were being
investigated, what thesis statement the authors present, what
conclusions were drawn and how this information is pertinent to the
class.
Ž
Literature Assignment 2 (Due April 2):
Using one of the three articles provided by Dr. Stoub (see webpage),
read the abstract, introduction and conclusions and skim the
article. Find one set of experimental results that supports the
author’s thesis statement. It may be worth your while to come and
talk to me about this. Read the portion of the article that
discusses this experimental result. In a 1 – 3 page paper, discuss
how the set of experimental results supports the author’s thesis. |

Reaction Mechanism Paper (9 %):
q
One important aspect of organic
chemistry involves understanding how researchers investigate how a
reaction works. Toward that end, each student will research a
particular reaction and explore the scope, mechanism and practical
applications for this reaction. The scope of a reaction defines the
type of molecules that can be reacted under the reaction
conditions. The mechanism explains how the reagents cause the
reaction to occur. The practical application refers to how this
reaction has been used for some relevant purpose. The main focus of
this article will be on the mechanism of the reaction. It is the
responsibility of the student to find a reaction of interest from an
appropriate organic chemistry journal. The student will “follow the
paper trail” in order to discover when the reaction was first
discovered and how researchers have subsequently studied the
reaction and, therefore, suggested a mechanism for the reaction.
This may require a literature search of related journal articles.
The student will analyze how the researchers have experimentally
investigated the mechanism and report on their findings. The paper
will be a 4 – 5 page paper discussing the scope, mechanism and
practical application of the reaction. |

q
All tests will be identical in format.
Each test will be cumulative but will focus on the material
presented in class and readings during that portion of the
semester. The cumulative nature is one of the biggest challenges of
organic chemistry; all the material builds upon itself; therefore,
do not get behind!
q
There will be two major sections to
each test.
§
Section 1: Questions will focus
on basic reactions and concepts. This section will include a couple
of multiple choice questions to prepare you for the final exam.
§
Section 2: Questions will focus
on using basic understanding and knowledge to solve problems. These
questions are designed in such a way that the first part of the
question should be elementary, the middle sections will explore your
understanding of the concepts and the final part will ask you to
apply what you know to a new and unknown problem.
§
Section 3: Retrosynthetic
analysis, synthesis or mechanism determination.
q
You must be present at the time of the
test as there will be no possibility to make up a test. If, however,
a serious event occurs that precludes your attendance to the exam,
YOU MUST contact me before the exam starts. We will then work
together to allow you to make up for the missed test. If you simply
do not show up, you will receive a 0 for the test.
q
The final exam is a multiple-choice,
standardized exam from the American Chemical Society. There are
several multiple choice type of questions in your book; I would
encourage you to practice using these problems. |
Each Test = 115 pts.
Final exam = 100 pts.
