Lecturers: Dr J Cockcroft, Dr B Slater, Prof D A Tocher

Normal prerequisite: CHEM1004

Aims

  • To introduce certain key aspects of inorganic chemistry, including solid state structures, the chemistry of phosphorus and hydrogen and transition metal chemistry.
  • To provide (via the laboratory course) training and experience in practical aspects of inorganic chemistry, including synthesis, qualitative, IR spectroscopy, and powder X-ray diffraction.
  • To introduce the synergy between the theoretical and practical aspects of inorganic chemistry via the close relationship of the laboratory work to the other components of the course. 

Objectives

At the end of the course students will be able to

  • explain certain key introductory concepts in inorganic chemistry (e.g. crystal field theory, common structural types, bonding)
  • to use these concepts in problem solving, describe and place in context the chemistry of main group elements (using phosphorus as an example) and transition metals,
  • use the skills developed in the laboratory course in qualitative and quantitative analysis and in the synthesis of inorganic compounds.
