Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: Werner's Coordination Theory, Important Terms in Coordination Chemistry, Nomenclature of Coordination Compounds.

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 45 questions available for this chapter.

3
Day 4

Revise & Test

Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.

Day 7

Spaced Revision

Come back to Coordination Compounds after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • Werner introduced primary (ionizable) and secondary (non-ionizable) valencies.
  • Secondary valency determines coordination number and geometry.
  • Complexes like [Co(NH₃)₆]Cl₃ dissociate into [Co(NH₃)₆]³⁺ and Cl⁻, not into Co³⁺ and NH₃.
  • Ligands donate electron pairs; donor atom is the bonding site.
  • Coordination number = number of bonds from ligands to metal.
  • Coordination sphere is enclosed in [ ] and remains intact in solution.
  • Ligands named alphabetically, prefixes ignored.
  • Anionic ligands: -o; neutral: common name.
  • Use bis-, tris- for ligands with internal prefixes.

Common Mistakes to Avoid

All salts that look like they have two components are double salts.

Coordination number is the total number of atoms in the complex.

Oxidation state of metal is always equal to the charge of the complex.

Memory Tips

Werner's Two Valences: Primary (ionizable) and Secondary (non-ionizable)

Coordination Number = Number of donor atoms attached to metal

Ligands: Monodentate, Bidentate, Polydentate
