Text and other Purchases:
- TEXT: same as Chemistry 2273a:
“Organic Chemistry, 7th Edition” by L. G. Wade.
- Laboratory Manual for Chemistry
2283G. See lab schedule below.
- Every Chemist should have a
decent molecular model set.
· Standard Lab safety items: Safety Glasses with side-panels, lab coat, long pants, closed toe shoes
Laboratory Schedule:
All Labs are carried out in the Chemistry Building Room 074 (lower ground floor). You must attend the laboratory section to which you are registered unless special arrangements are made with the TA’s. Lab reports should be handed in at the start of the next experiment.

This course is supported by the Science Student Donation Fund: If you are a BSc or BMSc student registered in the Faculty of Science or Schulich School of Medicine and Dentistry, you pay the Science Student Donation Fee. This fee contributes to the Science Student Donation Fund, which is administered by the Science Students’ Council (SSC). One or more grants from the Fund have allowed for the purchase of equipment integral to teaching this course. You may opt out of the Fee by the end of September of each academic year by completing paperwork in the Faculty of Science Dean’s Office. For further information on the process of awarding grants from the Fund or how these grants have benefitted undergraduate education in this course, consult the chair of your department or email the Science Students’ Council: ssc@uwo.ca.
Note regarding exams: It is the policy of the Department of Chemistry that when a student takes a test or examination, they have deemed themselves fit to do so. Claims of distress or medical issues after the fact will not be considered for the basis of a grade appeal.
Evaluation:
The final grade for the course will be determined by the following:
|
Lab Mark |
20% (attendance is mandatory) |
|
Quizes |
12% 2 quizzes, one before the midterm, one before the final. dates tba |
|
Term test |
28% |
|
Final Exam |
40% (cumulative) |
|
Total |
100% points |
Score (X) ........................Letter Grade
90.000 < X .............................A+
80.000 < X < 89.999 ..............A
70.000 < X < 79.999 ..............B
60.000 < X < 69.999 ..............C
50.000 < X < 59.999 ..............D
X < 50.000 .............................F
In order to pass you need i) a mark 50%, and ii) 50% or greater in your laboratory mark and iii) a passing grade in the final exam. The final exam must be written.
The raw course scores X can (and most likely will) be curved upward according to a standard T-score:
Raw scores earned on each of the exams in this course may be converted to Standard T-Scores at the discretion of the instructor. The Standard T-Score is computed as follows:
T = [(x-X)/s) •W] + Y
where:
x = your raw test score
X = the class mean score = S x/N
N = number of test scores
s = standard deviation = [S (x-X)2/(N-1)]1/2
Y = the Curved exam average, set by the instructor.
W = The weight of each standard deviation = 10 up to s (set by the instructor).
Using Standard T-Scores allows an effective averaging of grades without introducing a bias in favor of tests with the greatest standard deviations. Since it is based on a normal (Gaussian) distribution, it generally represents the fairest way of grading a large group. The instructor may increase Y (to raise everyone’s grade) or adjust W (so that the T-score curve more accurately reflects the raw score distribution).
Alternatively, marks might be modified by a “halfway to the goal” approach, where a 50 out of a 100 would be given up to an additional 25 points. This point value will usually be multiplied by a fixed percentage (say 80%), to give 20. Thus the final mark would become a 70. Also, the class average may be adjusted upwards by simply adding the same number of marks to each student’s total. Note, in recent years no curving of marks has been necessary.
|
What does this T-score mean for me? |
With this grading system, everyone will receive a score equal to their raw percentage score or their T-score or their halfway to the goal score, whichever is higher. That is, no grades will be lowered through the use of the T-score system. Note that curving of marks may not happen at all when the average is high enough. |
Additional Quizzes.
There is no opportunity for ‘extra credit.’ However, there may be additional
unannounced in-class quizzes. There will be no make-up opportunities
for the in class quizzes. Each quiz may contribute up to 1 total grade
point (out of 100), and will be additional to the regular points from exams and
homework. There will be no make up
quizzes. Generally there is a subtle hint that a quiz is eminent.
A Notice from the Registrar:
"Unless you have either the prerequisites for this course or written
special permission from your Dean to enroll in it, you will be removed from
this course and it will be deleted from your record. This decision may not be
appealed. You will receive no adjustment to your fees in the event that you are
dropped from a course for failing to have the necessary prerequisites."
Accessibility Statement: “Please contact the course
instructor if you require material in an alternate format or if you require any
other arrangements to make this course more accessible to you. You may also
wish to contact Services for Students with Disabilities (SSD) at 661-2111 x
82147 for any specific question regarding an accommodation.”
Accommodation by Instructor for work worth less than 10% of the overall grade in a course: Medical excuses processed through the deans office are required for missed quizzes, exams and labs. In the case of missed scheduled quizzes or midterm the final exam will weigh more.
