Model Kits in Discussion
It is important that you learn how to
use your molecular model kit. Some problems covered in discussion may
involve models, so please bring your molecular model kit to discussion
section for the next few weeks.
Extra Material on Molecular
Geometry and Hybrid Orbitals
Some of you are having difficulty with
the idea of hybrid orbitals. For another course I prepared a lecture on
molecular geometry and orbitals, which might help you understand the
topic a bit better. Download the PowerPoint

Several Chem 14C
students have lamented
that they did not get as much depth on molecular conformations in Chem
14B as they would have liked. If you are struggling with this topic,
try these sections and problems from the Vollhardt and Schore textbook,
and Organic Chemistry as a Second
Vollhardt and Schore 5th edition Chapter 2: Read sections 2-7 and 2-8,
problems 18, 19, 36, 37, and 49.
Vollhardt and Schore 5th edition Chapter 4: Read sections 4-1 to 4-5,
problems 1, 3, 5, 9, 22, 23, 25, 28-30, and 47-49.

you may have discovered by now,
sometimes it can be rather challenging to visualize the
three-dimensional structure of a molecule. This is especially
true when considering conformations and stereochemistry. Some --
but not all -- of you have also discovered the value of using your

You are allowed -- and strongly
encouraged -- to use your model kit during an exam. (Experience
suggests that students who do not use their models are at a
disadvantage.) Therefore it is very strongly recommended that you
practice the use your model kits with Thinkbook, OWLS and textbook
problems, and that you bring them to discussion sections, bring them to
office hours, sleep with them, and in general make them your best
studies buddies. To know and use your model kit is to love your

Weekly discussion sessions will feature OWLS (Organic
for Learning Success) problem sets, written by the
instructor. These are intended to develop your mastery of organic
by emphasizing problem solving skills. These problems sets will
used as determined by the Instructional Associates, based upon their
perceptions of your
Problem sets will be covered in discussion after the topic is
in lecture. Each lecture topic has its own associated problem
set. The problem sets are in your Thinkbook, whereas the answers are available
on-line only. So that you have an incentive to actually work
through the problems on your own, solutions will be posted about one
after the lecture discussion on the topic is complete.
"Why should I bother with discussion
A fair question! You may be tempted to skip discussion,
at 8 AM, but note that the OWLS problems sets are written by the same
who also writes the CFQ & PP and exams, suggesting OWLS problems
be excellent exam practice. In addition, course grade statistics
suggest that persistent use of OWLS problems leads to grade success. Discussion
section attendance is not mandatory, but is very strongly suggested.
Check out these statistics from a previous
that show a strong correlation of exam score with number of discussion
OWLS Problem Sets Solutions
Solutions will be
posted here about one week after the topic is covered in lecture.
Topics not included here do not have OWLS problem sets.

explains the format of the final exam, plus other issues concerning
grades and exams.
Use this scale to determine your
grade. The numbers
are based on exam scores and grade statistics for over 70 past
Hardinger courses. Even though these past courses used a sliding grade
scale, the exam
and course grades were fairly consistent, so this scale is on par
with past course grades. Important
the final exam has been graded, averages for all exams will be
calculated and compared to the grading scale shown below. An adjustment
to the grading scale may then be made, if warranted by
the exam averages. This adjustment, if necessary, will lower the
cutoffs (make grades easier to get) and not raise the
cutoffs. Therefore this grading scale really is an estimate
of the final scale curved in the traditional sense, and not a fixed,
immutable scale. If the grade scale changes, then the modified
scale will be posted here. The grading scale has only changed a few
the past decade, so it is reasonable
to assume it will remain fixed this quarter as well.
Progress Assessment Tools and Their Point Values
Exam 1 (100 points) + Exam 2 (100
points) + Final Exam (200 points) = 400 possible points
Extra credit is added after the grade
scale is set, and does not influence the grade scale.

| Are you an Einstein or an amoebae?
When an exam is returned to you, consider the following thought
to Karl Popper, an educational philosopher): "The difference between
amoebae and Einstein is that, although both make use of the methods of
and error or elimination, the amoebae dislikes erring while Einstein is
intrigued by it. He consciously searched for his errors in the
of learning their discovery and elimination."

- You can earn 0-2 points per two week period for your
participation in the course discussion board. These are extra credit
points. Submissions are evaluated and points awarded at the end
of each even-numbered week (week 2, week 4, week 6, week 8, and up to
the final exam.)
- Submission are evaluated on quality and (to a lesser extent)
quantity. Submissions that are more relevant, more detailed, more
correct, more precise, and overall more useful to other students in the
class will have a greater chance of earning credit. Spelling and
accurate use of vocabulary words count as well. As the quarter goes on
(and your mastery of the course material, in theory, improves), the
standards used to judge the quality of discussion board posts becomes
more strict. In other words, as the quarter goes on, strive to improve
the quality of your posts.
- One submission = one question or one answer. One submission is
worth at most one point. Not all submission will earn a point.
- Any thread or reply that contains a significant conceptual or
vocabulary error cannot earn credit.
- Some discussion board questions may be used as exam questions,
regardless of their credit worthiness. Therefore it is useful to read
all discussion board posts, even if you do not post any yourself.
- When you copy part or all of an answer from another source, you
must cite the source. (A web link is useful for this.) As is true in
any other circumstance, copying someone else's words without giving
credit is plagiarism. Plagiarism is an act of significant academic
misconduct, and carries appropriate penalties.
- Profane, disrespectful, or inappropriate postings will be
removed. Penalties depend upon the nature of the infraction and are
decided by the discussion board moderator. Treat others as you
would like to be treated.
- For the purposes of this project, the two-week period starts
Monday 12:01 AM (as determined by the discussion board clock) and runs
fourteen calendar days. The last period begins Monday of week nine and
runs until the moment the final exam begins.
- You must be registered at the discussion board web site in order
to make submissions.
- Please include the page number and problem number in the title of
your new thread when asking a question concerning Thinkbook problems
and solutions. Example: Thinkbook page 105 CFQ 1(a). Similarly, please
include the problem number, exam number, and quarter in the title when
asking about an old exam. Example: Spring 2008 Exam 1 Question 6.

Think of the
discussion board as a project that lasts all quarter, but isn't graded
until it is complete (like a ten-week long quiz). Just like a quiz, you
can't stop in the middle and ask your score. Your discussion board
participation point total will be written on the front of your final
exam (after the exam is graded), so you can see your score when you
collect your final exam. Like exam scores and course grades, discussion
