Aims

To introduce and discuss four important and diverse areas of inorganic chemistry. To lay the theoretical and practical foundations for advanced courses in some of these areas taken later. To encourage students to investigate these topics by reading beyond the lecture material.

Objectives

Students should be able to:-

  • Relate and discuss the differences between the chemistries of the lanthanides and actinides. Account for the differences between these chemistries and that of the d-block elements
  • Give an account of modern materials processing and the chemistry that underpins it
  • Deduce synthetic routes to organometallic compounds. Account for reactivities in tems of kinetic and thermodynamic factors. Describe some applications of organometallic compounds
