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.

This course is flip taught, that is you view recorded lectures on Panopto and tutorials are held to assist your understanding.

The laboratory component of this course is compulsory and will be taught as a block course over two weeks commencing in week 46.

The block laboratory course runs over ten days and on each day the students will undertake a practical laboratory experiment for three hours in the morning and in the afternoon write up the report of the morning's work and submit this report the same day.

Tutorials will be held throughout the C trimester, as indicated in the timetable.

The first test will be held on Tuesday 14th December 2021.

The second test will be held on Thursday 27th January 2022.

There is a compulsory final examination during week beginning February 14th 2022.

Assessment

Edit Assessments Content

Important note:

At this stage it is assumed that all assessment items, Tests 1 and2, and the final test or examination will occur on campus and in person.

These items will NOT be open-book.

In the event of a lockdown preventing in person assessment, each assessment item will be replaced by a 50:50 mark split between an online open-book written assessment and an individual oral examination; the latter will NOT be open-book. In the event that your mark for the oral assessment is significantly lower than your mark for the written assessment, you will have an opportunity to sit a second oral assessment and if there continues to be a disparity between your performance in the two parts of the assessment you will be required to undertake an in-person written test. In the event that the oral examination occurs via Zoom or some similar program, you will be required to have video operating, to look at the camera during the examination and to have your hands in view. If you do not operate with video, you will be deemed not to have undertaken the oral assessment item.

We have been obliged to impose these measures because in 2020 a significant number of students were caught taking advantage of online assessment to cheat.

Your attention is directed to the student code of conduct which specifically excludes plagiarism or copying the written material of others and purchasing answers from online agencies.

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 are two tests in the course, please consult the detailed timetable below for scheduling.
