Specification

Pre and co requisites

Student to have taken the Level 4 Inorganic Chemistry course or equivalent

Aims

This course develops the content of the Level 4 course Inorganic Chemistry. It covers two areas of inorganic chemistry. In the first, it develops models of metallic and ionic structures. In the second, it covers transition metal complexes, models of bonding in complexes, the redox chemistry of transition metal compounds and the application of concepts involving complexation and redox chemistry to mechanisms for catalysis. The course as a whole therefore places inorganic chemistry within a wider context and applies concepts met in other courses.

Learning outcomes

On successful completion of this course a student will be able to:

Learning Outcome
1 Apply extended knowledge of group 13 -18 chemistry for groups
2 Apply models to explain structures of crystalline materials
3 Investigate and classify transition metal co-ordination complexes
4 Apply theoretical models to explain the behaviour of transition metal co-ordination complexes
5 Predict, investigate and evaluate the redox and catalytic behaviour of transition metal compounds
6 Practical skills and ability to report laboratory activities/analyse laboratory acquired data

Teaching and learning activity

The course will be delivered mainly through lectures and tutorials. A series of practical exercises will illustrate the principles taught in lectures (BSc/MChem students only). The underlying principles will be explained in the lectures, and the tutorials will establish the understanding of these principles and their application. Some of the topics will be supported by interactive computer learning exercises. Independent reading by students will be encouraged.
