EXAMINATION In Physical Chemistry there will be three written assign- ments during the course of the year, performance in which will be taken into account in assessing the final result. These assignments account for one-third of the total mark for Physical Chemistry. There will also be three hours of written examination to be held In the Science faculty exam weeks or at the end of the year. In Organic and Inorganic Chemistry there will be assignments and tests throughout the course and these will be taken into account in determining the candidate's success in the year's work. The final examination will consist of one 2-hour written paper in Inorganic Chemistry, and one 2-hour written paper in Organic Chemistry.
200 LEVEL
The Chemistry School, consisting of the Departments of Physical, Or- ganic and Inorganic Chemistry, offers the following units at the second level. To assist students who wish to choose Chemistry as a major or sub-major study, three categories of course are set out below, designed for students taking respectively a full Chemistry major, Chemistry with a biological science, and Chemistry with Mathematics or another physical science. Courses in these categories have been approved In advance for Chemistry majors and sub-majors. Any student wishing to construct a Chemistry major or sub-major course differing from those set out below must submit his proposed course for approval, to a panel of Chemistry School course advisors at the appropriate time.
Category A
For students majoring in Chemistry only. These students must enrol for a minimum of 20 points in Chemistry, made up as follows:
Physical: any one of 203, 204 (each 6 points) or 205 (7 points) Organic: 222 (6 points)
Inorganic: 240, 241 (6 points total) Analytical: 260 (2 points). , Category B
For students majoring in a biologicai science, together with Chemistry.
These students must enrol for a minimum of 14 points in Chemistry, made up as follows:
108
CHEMISTRY Physical: 201 or 202 (5 and 6 points respectively)
Organic: 221 (5 points) Inorganic: 243 (2 points) Analytical: 260 (2 points)
Note that there is an approved course corresponding to this at the 300 level.
Category C
For students majoring in Mathematics or another physical science, to- gether with Chemistry. These students must enrol for a minimum of 16 points in Chemistry, made up as follows:
Physical: Any one of 201 (5 points), 203, 204 (6 points each) or 205 (7 points)
Organic: 220 (4 points)
Inorganic: 240, 242 (5 points total) Analytical: 260 (2 points).
Note that there is an approved course corresponding to this at 300 level.
Practical Work
Physical: All physical chemistry laboratory work is combined with theory for the purposes of examination.
Organic: 42 hours of laboratory work designed to provide illustrative material for 200 level organic chemistry units and training in technique is combined with each of the theory units for the purpose of examina- tion. Satisfactory completion of the practical work is necessary before any credit is granted for the units.
inorganic: Satisfactory performance In the practical components of units 241 and 242 is required before credit for the associated theory units can be given. Students enrolled for only 2 points-worth of inorganic theory units are not required to undertake inorganic practical work.
Analytical: Enrolment in unit 280 (42 hours practical together with 8 lectures) is compulsory for all students in categories A, В and C and for all Science faculty students enrolled for other units of Chemistry worth 10 or more points.
EXAMINATIONS Units may be examined at fixed times throughout the year, and in the examination term at the end of the year. In general, a minimum of 10 200-level Chemistry points must be credited before per- mission will be granted a student to enrol for any 300-level Chemistry units.
PREREQUISITES Physical: Any one of 201, 202, 203, 204 or 205 is a prerequisite for any 300 level Physical Chemistry unit. Organic: Any one of 220, 221 or 222 is a prerequisite for any 300 level Organic Chemistry unit.
