<strong>Chem</strong>istry-1<br />
Course <strong>Handbook</strong><br />
2008 – 2009<br />

FOREWORD<br />
Welcome to first year <strong>Chem</strong>istry. Whether your intention is to stay with us to<br />
complete an Honours B.Sc. or an M.Sci. degree in one <strong>of</strong> the <strong>Chem</strong>istry options, or to study<br />
for some other degree, we hope you will enjoy and benefit from your time spent studying<br />
chemistry.<br />
The <strong>Chem</strong>istry-1 course has been designed to be both useful and interesting to all<br />
students by providing a firm basis for later courses in <strong>Chem</strong>istry and other subjects. The<br />
<strong>Chem</strong>istry-1 course is not easy; no course at <strong>University</strong> should be easy. It is challenging<br />
and will be a major change from school/college chemistry. The onus is on you to read,<br />
discuss and practise during the year. In addition to lectures and laboratory courses, you will<br />
be required to attend problem sessions, which are intended to help you to understand the<br />
concepts, to discuss these and to practice them by answering appropriate questions.<br />
At university, with the large classes, you will have to organise your study time,<br />
check your progress and, if you have difficulties, ask for help. Nobody is penalised for<br />
asking for help or further explanation. The staff are here to help you, but we can only help if<br />
we know you have a problem. There are regular voluntary tutorials where you can ask<br />
questions. You can also ask the lecturer or any member <strong>of</strong> staff in problem session or<br />
laboratory if you require help. For any matters relating to administration or personal<br />
problems please consult the class head, Pr<strong>of</strong> Bob Hill.<br />
It is essential that you read this <strong>Handbook</strong> carefully and thoroughly. I would draw<br />
your attention, particularly, to the sections dealing with the Award <strong>of</strong> Credits and Absence. It<br />
is important that we have full details <strong>of</strong> any absences through illness or other problems<br />
during the year in order that these may be taken into account in the assessment <strong>of</strong> your<br />
work at the end <strong>of</strong> the course.<br />
I am sure that you will find the <strong>Chem</strong>istry-1 course interesting<br />
and enjoyable and that you will be successful at the end <strong>of</strong> the course. I look forward to<br />
welcoming many <strong>of</strong> you into the <strong>Chem</strong>istry-2 course in a year’s time.<br />

ENROLMENT<br />
All students in the class must register, complete a class enrolment form and pay a fee <strong>of</strong><br />
£10 (collected in the lab in week 3) for the lab manuals, safety glasses and other materials<br />
provided.<br />
TEACHING AND LEARNING<br />
LECTURES<br />
There are 75 lectures, given Monday to Thursday and some Fridays<br />
over 22 weeks. The class meets in two sections, one at 10 a.m. and<br />
one at 3 p.m., in the Joseph Black Building Main Lecture Theatre (B4-<br />
19). It is important to only go to the lectures at the time allocated to<br />
you (once labs have been assigned).<br />
Enter the Department by the central entrances.<br />
Come in at the back <strong>of</strong> the theatre (level 5) and go out at the front <strong>of</strong><br />
the theatre (level 4).<br />
Lectures provide facts, theories, demonstrations, textbook references<br />
and background. An outline timetable is given on page 13 <strong>of</strong> this<br />
<strong>Handbook</strong>. Guidance is also given on what you should be able to do<br />
(Objectives) by the end <strong>of</strong> each group <strong>of</strong> lectures from pages 14 to<br />
24.<br />
PROBLEM<br />
SESSIONS<br />
LABORATORY<br />
LEARNING<br />
On some days the lecture time is used for problem-solving<br />
workshops. Supplementary problems will be provided for you to work<br />
on at home. More details are given on page 8.<br />
Each student will attend one three-hour laboratory class per week<br />
starting in week 4. Lab times are M, Tu, W, Th 2 - 5 and Tu, W, Th, F<br />
10 - 1. You will be assigned a day and told your bench and first<br />
experiment number. More details are given on page 7.<br />
Involves all <strong>of</strong> these plus text books (see page 12), private study and<br />
practice, general reading and discussion.<br />
In lectures try to note down what is on the board or screen and as much as you can <strong>of</strong> the<br />
key points <strong>of</strong> what is said. As soon as possible fill out your notes from memory, by<br />
collaborating with a friend and by looking up books to reconstruct the full story.<br />
We know that you will not always understand topics fully during the lecture. Later reading,<br />
digestion, discussion and practice are needed. Book references will be given in lectures.<br />
Look them up and incorporate diagrams, examples etc. from them into your notes.<br />
Keep the lecture notes safe, in a binder with your name and class. Lecturers cannot provide<br />
copies <strong>of</strong> lecture notes and it is expensive to photocopy other students' notes if you lose<br />
yours and they can never be as good as your own. Students who “skip” lectures <strong>of</strong>ten find it<br />
very difficult to catch up with their work. The purpose <strong>of</strong> a lecture is to help you understand<br />
the material - not just to give you a set <strong>of</strong> notes. So attendance at all lectures helps you<br />
to understand the chemistry.<br />

ASSESSMENT<br />
The final mark for the course will be made up as follows:<br />
Laboratory work 10%<br />
Class exam (2h)<br />
30% (covering Semester 1 work)<br />
Short tests<br />
10% (4 tests in lecture times)<br />
End <strong>of</strong> course exam (2h) 50% (covering the whole year’s work but with the emphasis on<br />
Semester 2)<br />
Previous exam papers will be available (see page 10) so you will know roughly what to<br />
expect. Exams include lecture, lab, tutorial, and problem session material, knowledge,<br />
understanding and application. As 50% <strong>of</strong> the final mark is from continuous assessment it is<br />
important to work steadily throughout the year.<br />
MINIMUM REQUIREMENTS FOR THE AWARD OF CREDITS<br />
Students may be awarded credits for the course only if they meet the following<br />
requirements:<br />
• attend lectures<br />
• perform satisfactorily in the mid-year class examination<br />
• sit the four class tests<br />
• have a good attendance record in laboratories and problem sessions<br />
• achieve a satisfactory standard in the laboratory work<br />
• sit the end-<strong>of</strong>-course examination.<br />
Normally no grade or credits shall be awarded to a candidate who has not met these<br />
requirements.<br />
EXAMINATIONS<br />
The Class examination (2 hours) will take place in December (time still to be fixed). The end<br />
<strong>of</strong> course examination (2 hours) will be in April or May. Advice will be available on the<br />
format <strong>of</strong> the exam and papers from previous years can be purchased from the Alchemists<br />
Club (see page 10) and are also available from the <strong>University</strong> Library.<br />
It is important that you do well in the Class examination as this forms 30% <strong>of</strong> your<br />
final assessment. A poor performance will put pressure on you to work significantly harder<br />
for the end <strong>of</strong> course exam. You do not get a second chance with the class exam. It is<br />
vitally important for you to plan your work from the start with this in mind. Extenuating<br />
circumstances (e.g. illness) at exam times must be reported to Pr<strong>of</strong> Hill at the time and<br />
supported by a medical certificate or other appropriate documentation. A copy <strong>of</strong> last year’s<br />
class examination is at the back <strong>of</strong> this handbook.<br />
Please note that all examinations should be written on the right-hand pages <strong>of</strong> the exam<br />
book in ink. Please do not use red pens as this can cause confusion when the papers are<br />
marked. Periodic tables will be available in examinations. You should provide your own<br />
calculator for examinations. Programmable calculators are not allowed.<br />
5
CLASS TESTS<br />
Four class tests will take place on Fridays (October 24th, November 21 st , February 13 th and<br />
March 20 th ) at normal lecture times in the lecture theatre that you use for the problem<br />
sessions. Each test lasts 30 minutes allowing time for settling down before the test and<br />
collection <strong>of</strong> test papers afterwards. A sample Class Test will be handed out during the<br />
week before each test.<br />
The purpose <strong>of</strong> the tests is to encourage you to work steadily throughout the year and to<br />
give you an indication <strong>of</strong> your progress. Students who perform poorly in a Class Test will be<br />
expected to attend revision tutorials, normally given by Pr<strong>of</strong> Hill, at times displayed on the<br />
notice board.<br />
It is important that if you are absent from any <strong>of</strong> the class tests or examinations that you<br />
explain your absence to Pr<strong>of</strong> Hill otherwise this will affect your continuous assessment.<br />
ABSENCE FROM CLASSES<br />
ABSENCE FROM CLASSES FOR MORE THAN FIVE TERM DAYS<br />
should be explained by a doctor's medical certificate or similar document which MUST be<br />
submitted to the<br />
Registrar’s Enquiry Office, Main <strong>University</strong> Building<br />
The medical certificate will be copied by the Registrar’s Office to all the Class Heads <strong>of</strong> the<br />
subjects you take and your Adviser <strong>of</strong> Studies.<br />
ABSENCE FROM CLASSES FOR LESS THAN FIVE TERM DAYS<br />
may be explained by a 'Self Certificate <strong>of</strong> Absence' (available in the Science Faculties Office<br />
and submitted to<br />
Science Faculties Office, Boyd Orr Building<br />
For the overall assessment <strong>of</strong> the course, attendance credits will only be given if<br />
absence was adequately explained by one or other <strong>of</strong> these routes.<br />
IN ADDITION to these certificates you must inform Pr<strong>of</strong> Bob Hill by letter or email<br />
(bobh@chem.gla.ac.uk).<br />
6
LABORATORY PRACTICAL WORK<br />
The laboratory work (3 hours per week) is designed to give you practice in safely and<br />
accurately carrying out preparations, analyses or measurements, reporting and interpreting<br />
results.<br />
It also <strong>of</strong>fers a chance to<br />
undertake chemical reactions yourself<br />
operate instruments and collect experimental data<br />
think about experiment design<br />
check your understanding <strong>of</strong> particular topics<br />
talk to demonstrators<br />
Concepts, procedures and knowledge met in the lab may appear in written exams. Your<br />
reports and oral answers will be marked and these marks and your attendance record<br />
contribute to the award <strong>of</strong> lab grades and count for 10% <strong>of</strong> the overall mark.<br />
Attendance is compulsory. Absences should be explained as above. If you miss a lab (for<br />
whatever reason) you should see Pr<strong>of</strong> Hill to arrange for an alternative time to complete that<br />
lab. Remember that some concepts introduced in the lab (but not lectures) will be included<br />
in the examinations.<br />
You require a white lab coat for the labs - you will be provided with a lab manual and safety<br />
glasses which you must bring along and wear at every lab.<br />
Labs start in week 4 with a workshop on laboratory calculations.<br />
SUMMATIVE ASSESSMENT<br />
All feedback on coursework used in assessment, including mid-year class exam/class test<br />
marks and laboratory grades, is strictly provisional for your guidance only, and is subject to<br />
ratification by the Board <strong>of</strong> Examiners and External Examiners at the end <strong>of</strong> the academic<br />
year. The <strong>University</strong> code <strong>of</strong> assessment is given in the General Section (page Gen. 10) <strong>of</strong><br />
the <strong>University</strong> Calendar 2008/2009 (www.glasgow.ac.uk/senate/calendar/current.html).<br />
PLAGIARISM<br />
Students are reminded that regulations regarding plagiarism (copying) apply to all work<br />
contributing to assessment, including lab. reports and class tests. Except where specifically<br />
directed, as part <strong>of</strong> a group project for example, all assessed work must be your own.<br />
Copying <strong>of</strong> lab reports, for example, is plagiarism - students may share data, where<br />
appropriate - but the report must be your own. See page Gen.48 <strong>of</strong> the <strong>University</strong> Calendar<br />
2008/2009 (www.glasgow.ac.uk/senate/calendar/current.html).<br />

PROBLEM SOLVING SESSIONS<br />
These will be held at the normal lecture times (PS on timetable) and their purpose is to<br />
practise using the knowledge you have gained from lectures and to prepare you for the<br />
laboratory work.<br />
Equipment<br />
You will need a calculator giving scientific notation and logs to base 10 (log x) and logs to<br />
base e (ln x) and inverse functions. Please note that programmable calculators are not<br />
allowed in <strong>University</strong> examinations.<br />
You will be provided with a periodic table that will be needed at some <strong>of</strong> the problem<br />
sessions (and can be used in class tests). A periodic table will be provided in the class exam<br />
and the end-<strong>of</strong>-course exam. Keep this periodic table unmarked for test purposes.<br />
Procedure<br />
The topics <strong>of</strong> the sessions will be announced in advance. After a short introduction you will<br />
be asked to work through the problems collaborating with friends if you wish. Several tutors<br />
will be available. Raise your hand if you need help with the problems. Answers and<br />
explanations will be given as the session progresses but it is no use sitting waiting till they<br />
are displayed - you will not have learned anything unless you work at it yourself.<br />
Sometimes supplementary problems will be provided for you to try at home.<br />
Solutions<br />
The complete solutions to the problem sessions will be displayed on the <strong>Chem</strong>istry-1 on the<br />
web: http://www.chem.gla.ac.uk/teaching/student_notices/year1.htm.<br />
Attendance at problem sessions is compulsory (See Award <strong>of</strong> Credits). Absence for<br />
good reason should be explained (see above). If you were absent for good reason you can<br />
get copies <strong>of</strong> the sheets from Pr<strong>of</strong> Hill.<br />
Mobile Phones<br />
Please note: mobile phones must be switched <strong>of</strong>f during lectures, labs, problem sessions,<br />
tests, examinations and in the library.<br />
8
REVISION TUTORIALS<br />
If you are having problems with a particular course you should see the lecturer concerned.<br />
Revision tutorial sessions have been timetabled on certain Thursdays at normal lecture<br />
times in the Main Lecture Theatre. These are not compulsory, but they do give an<br />
opportunity for students to ask questions. Tutorials are normally given by Pr<strong>of</strong> Hill.<br />
CLASS NOTICES<br />
Class notices, are posted in the <strong>Chem</strong>istry-1 display case on the ground floor <strong>of</strong> the central<br />
block <strong>of</strong> the Joseph Black Building. Problem Session answers, details <strong>of</strong> laboratories and<br />
results <strong>of</strong> class tests, class exam and laboratory grades will also be displayed. It is<br />
important to look at this Notice board regularly for details <strong>of</strong> any class information,<br />
particularly if you have been absent for some reason. Weekly Class News will be e-mailed<br />
to your student e-mail address. You must check this regularly.<br />
GRADE POINT AVERAGES: GUIDELINES<br />
The grade awarded at the end <strong>of</strong> the course contributes towards you Grade Point Average.<br />

Total grade points = sum <strong>of</strong> credits x grade points<br />
Grade point average (GPA) = Total grade points/Total credits<br />
The grade point average and credit level requirement for B.Sc. and M.Sci. are given in full in<br />
the <strong>University</strong> <strong>of</strong> <strong>Glasgow</strong> Calendar and the Catalogue <strong>of</strong> Courses. Please consult your<br />
adviser <strong>of</strong> studies for full details. Some <strong>of</strong> the key points are listed below.<br />
1. Your grade point average should normally be at 10 or above in each year <strong>of</strong> study.<br />
2. Entry into level-3 courses requires a grade point average over the first two years <strong>of</strong><br />
above 11 for B.Sc (Hons) and above 12 for M.Sci.<br />
3. Entry to many level-3 courses is on a competitive basis with a preference given to<br />
those students with a high grade point average.<br />
4. In addition some level-3 courses have a minimum grade requirement for entry.<br />
It is therefore important that you make sure you work steadily throughout the year in every<br />
subject. Low grades may cause problems with progress.<br />

STAFF-STUDENT COMMITTEE AND OPINION SURVEYS<br />
At the start <strong>of</strong> the session we will invite students in the <strong>Chem</strong>istry-1 class to volunteer to join<br />
the <strong>Chem</strong>istry Staff-Student Liaison Committee which discusses courses and other<br />
departmental business once or twice a term. These students have a special responsibility to<br />
alert staff <strong>of</strong> any problems that develop in the running <strong>of</strong> the <strong>Chem</strong>istry-1 course.<br />
All students will have an opportunity at some time to comment on aspects <strong>of</strong> the course via<br />
questionnaires. Any difficulties are most quickly resolved by informing Pr<strong>of</strong> Hill.<br />
ALCHEMISTS' CLUB<br />
The chemistry students club organises lectures, sports etc. and sells reprints <strong>of</strong> past exam<br />
papers. The papers will be sold during labs or at the end <strong>of</strong> lectures. If you have problems<br />
getting them see the Alchemists web site at http://www.chem.gla.ac.uk/alchemist/.<br />
BEYOND CHEMISTRY-1<br />
The following 30-credit courses are available in second year. Both <strong>Chem</strong>istry-2X and<br />
<strong>Chem</strong>istry-2Y are required to continue with “<strong>Chem</strong>istry” courses beyond level-2. Similarly<br />
both Environmental <strong>Chem</strong>istry-2A and 2B are required to continue with “environmental”<br />
subjects beyond level-2 It is possible to do all 4 courses (120 credits).<br />
<strong>Chem</strong>istry-2X – Molecules matter – the fundamentals<br />
Taught throughout the year in parallel with <strong>Chem</strong>istry-2Y. The course is designed to give a<br />
deeper understanding <strong>of</strong> the behaviour <strong>of</strong> molecules and beyond into solid state chemistry.<br />
The topics covered include molecular thermodynamics, organic stereochemistry, solid state<br />
chemistry, quantum mechanics, chemical bonding and symmetry, main group chemistry,<br />
organometallic chemistry and enols and enolates.<br />
<strong>Chem</strong>istry-2Y – <strong>Chem</strong>istry <strong>of</strong> the natural world<br />
Taught throughout the year in parallel with <strong>Chem</strong>istry-2X. The course is designed not only<br />
to be useful for intending chemists but also for those students who are intending to pursue<br />
degrees in biology at the molecular level such as biochemistry, pharmacology, genetics etc.<br />
Topics covered include spectroscopy, kinetics, aromatic chemistry, co-ordination chemistry,<br />
organic synthesis, biophysical chemistry and applied organic chemistry. Both <strong>Chem</strong>istry 2X<br />
and 2Y are required for entry into level-3 courses in <strong>Chem</strong>istry, <strong>Chem</strong>istry with medicinal<br />
chemistry, <strong>Chem</strong>istry with forensic studies, <strong>Chem</strong>istry and mathematics, Biology and<br />
chemistry and <strong>Chem</strong>ical Physics.<br />
Environmental <strong>Chem</strong>istry-2A – The natural environment<br />
Taught in the first semester. This course aims to describe the chemistry and functioning <strong>of</strong><br />
the components <strong>of</strong> the natural environment, the interactions between these components and<br />
the processes which operate within and between them. This will provide an understanding<br />
<strong>of</strong> the chemistry <strong>of</strong> rocks, soils, sediments, water, air and living organisms. Particular<br />
attention will be paid to the processes which cause mobilisation or immobilisation <strong>of</strong><br />
chemical species, their mobility and cycling between the different environmental<br />
components. The chemistry <strong>of</strong> environmental materials and processes and the chemical<br />
analysis <strong>of</strong> environmental samples are strongly emphasised to provide a sound scientific<br />
background for understanding environmental problems and for monitoring, controlling and<br />
cleaning up pollution.<br />
10
Environmental <strong>Chem</strong>istry-2B – Environmental systems and pollution<br />
Taught in the second semester. This course aims to describe the chemistry and behaviour<br />
<strong>of</strong> environmental systems and the effect <strong>of</strong> human activity on them. The course acts as an<br />
introduction, along with Environmental <strong>Chem</strong>istry 2A, to the subjects covered in greater<br />
detail in the honours courses in Environmental <strong>Chem</strong>istry; Environmental Biogeochemistry<br />
and Environmental <strong>Chem</strong>istry and Geography. Environmental <strong>Chem</strong>istry 2A, The Natural<br />
Environment, should be taken as a co-requisite to provide entry to the level-3 courses in<br />
“environmental” subjects, but each is a complete course in its own right, suitable for<br />
students intending to proceed to level-3 in other subjects. These two courses also provide<br />
an appropriate chemical background for students intending level-3 in biological, geographic<br />
or earth sciences.<br />
CHEMISTRY BEYOND LEVEL 2<br />
There is a wide range <strong>of</strong> “chemistry” options available beyond level-2. Some degrees are<br />
also available with Work Placement or European Placement opportunities. The following list<br />
gives all the possibilities. Final decisions about degree choice are made at the end <strong>of</strong><br />
second year. *Subject to approval by Senate<br />
