Key Topics to Revise

1

1. Werner's Theory and Basic Terms

  • Alfred Werner first formulated the theory of coordination compounds.
  • Werner proposed two types of valence: primary valence and secondary valence.
  • Primary valence is ionisable and is satisfied by negative ions.
2

2. Ligands, Denticity, and Chelation

  • Ligands may be simple ions, small molecules, or large molecules.
  • Unidentate ligands bind through one donor atom.
  • Didentate ligands bind through two donor atoms.
3

3. Nomenclature of Coordination Compounds

  • The formula of a coordination compound is written with the metal first, then ligands in alphabetical order.
  • The whole coordination entity is enclosed in square brackets.
  • When the coordination entity is charged, the charge is written outside the brackets as a right superscript.
4

4. Isomerism in Coordination Compounds

  • Isomers have the same chemical formula but different arrangement of atoms.
  • Coordination compounds show stereoisomerism and structural isomerism.
  • Stereoisomerism includes geometrical and optical isomerism.
