CHEM1046 Fundamentals of Inorganic Chemistry II for non-chemists
Aims and Objectives
The aim of this course is to provide a core for future studies in chemistry and allied subjects, in aspects of inorganic chemistry as specified below Teaching in this course recognises the diversity of our intake in terms of A level syllabus followed and choice of non-Chemistry A level subjects (maths, physics, etc.). Lecture component: The aim of the NMR section of the unit is to provide an introduction to modern NMR spectroscopy, and structure prediction and solution using the technique. The aim of the Transition Metal Elements section of the unit is to provide an introduction to coordination chemistry and the chemistry of compounds of the transition metal elements. The primary objective of the Main Group Elements section of the unit is to provide an introduction to the ‘descriptive chemistry’ of the elements and to demonstrate how electronic properties can influence reactivity, atomic size and other physical and chemical properties of the elements.
Having successfully completed this module you will be able to:
- Describe the physical basis, the limitations and the information available from NMR spectroscopy as a structural method.
- Qualitatively predict and/or interpret the NMR spectra of simple molecular species.
- Qualitatively discuss simple trends in the physical properties of transition metals and their formation of coordination complexes with ligands.
- Describe bonding models that can be applied to a consideration of the properties of transition metal compounds.
- Recognise fundamental variables and general trends across the periodic table and predict molecular geometries and structures, recognising the importance of inert-pair effect, coordination geometries, oxidation state, electronegativity, ionisation energy, VSEPR, etc..
- Identify the structures and properties of some important Groups 13-18 elements and their compounds with a view to gaining a better understanding of broad diversity in their chemical properties, their importance in the natural environment and their role in the development of bonding theories.
