Paper Description

Edit Paper Description Content

This paper is a theoretical and practical course designed to provide a basic grounding in aspects of chemistry that are required for a Chemistry major, or students wanting to take higher level ‘core’ chemistry papers in Analytical or Inorganic Chemistry

There are two key themes to the paper:

In the first theme, analytical methods are explored, including the important role played by statistics and errors when the collection of data is involved. The analytical techniques are chosen to be those that have importance in modern chemistry, with a strong focus on spectroscopic techniques, including UV-visible spectroscopy, elemental analysis techniques, Infrared spectroscopy and NMR spectroscopy. As part of the course, students will gain hands-on experience in the operation of analytical instrumentation.

In the second theme, structure and bonding will be explored, including atomic and molecular structure, periodic properties of the elements, and chemical bonding. Following this, the most important structures adopted by metals will be covered, together with a selection of modern materials including siloxane polymers.

Students will develop skills in the writing of laboratory reports as part of this paper.

Paper Structure

This paper is taught through a combination of lectures, tutorials and laboratory sessions. Chemistry is an inherently practical subject and there is a focus on students gaining the necessary laboratory skills to be successful in Chemistry.

Lectures are held three times per week and are supported by recordings of these lectures using Panopto software. These recordings can be accessed at any time via the online learning platform (Moodle), via the course Moodle page. Recorded lectures will be very useful as a study aid, or in cases of illness or other unavoidable absence, or to cover timetable clash(es), however they should not be considered as a long-term alternative to attending lectures.

Tutorials are held for students to get assistance with the problem sheets and all other aspects of the course.

Laboratory sessions begin on the first week of semester i.e. Tuesday 27th February 2018. Students must attend their allocated laboratory session unless they have written documentation (e.g. medical certificate) explaining why they couldn’t attend their normal session.

Laboratory work

Requirements for the laboratory write-ups will vary for each experiment. Further details will be specified in the Laboratory Manual, and discussed in laboratory classes.

Tests

There will be four tests in the course, totalling 20% of the total course mark overall. Please note these dates in your diary.

An online Moodle test (Test 1) will be held in week 2 of the course: further details of this test will be announced on Moodle in due course. This will count 4% towards the final grade for the paper.

There are two full, written tests in the paper (worth 6% each) which will be held on the following days and times

Test 2 Wednesday 28th March 7:30-8:30 pm, PWC Lecture Theatre

Test 3 Wednesday 9th May 7:30-8:30 pm, PWC Lecture Theatre

Finally, a multiple-choice test (Test 4) will be held during the lecture time on Wednesday 30th May. This will count 4% towards the final grade

For each test, around two weeks additional notification will be given in the form of a Moodle announcement which will also contain the weighting of topics to be tested.

If you are not intending to study chemistry for 3 years it is possible to purchase an e-edition which will remain current for two years or to purchase individual chapters. These can be found at:

http://www.cengagebrain.co.nz/shop/en/NZ/storefront/newzealand?cmd=CLHeaderSearch&fieldValue=skoog

Other Resources

Edit Other Resources Content

Lecture notes can either be downloaded and printed from the Moodle page, or alternatively a complete, bound set of lecture notes can be purcahed from Waikato Print. The laboratory manual can likewise either be self-printed, or a bound copy purchased.

Lectures will be recorded using Panopto, though we are unable to guarantee the quality or even existence of recordings in the unlikely event that serious technical issues arise.

For those students planing to continue in Chemistry, to CHEMY102 Chemical Reactivity, and CHEMY201 Organic Chemistry and CHEMY203 Inorganic Chemistry, a molecular model kit will be a valuable tool for the three-dimensional visualisation of molecules. These can be bought from internet trading companies, or alternatively the Chemistry Programme has a limited number for sale. To view and/or purchase one of these please contact Bill Henderson in the first instance.
