Start your practice with these. Each one has appeared in several different years, so it is worth knowing the question styles.
What the syllabus covers
Werner's theory, ligands, coordination number, IUPAC nomenclature, isomerism, valence bond approach, crystal field theory, colour and magnetic properties, importance of coordination compounds.
A checklist to tick off:
- Werner's theory
- Ligands
- Coordination number
- IUPAC nomenclature
- Isomerism
- Valence bond approach
- Crystal field theory
- Colour and magnetic properties
- Importance of coordination compounds
What to focus on
IUPAC naming, isomerism, hybridisation and magnetic moment from crystal field theory, and the spectrochemical series. It is the heaviest chapter in Chemistry, so make it a strength.
A study plan for this chapter
Because it is gaining weight, move it up your list and give it extra practice. If you divide your Chemistry time in proportion to recent weightage, this chapter earns about 8% of it.
- Week 1: one careful pass through theory and solved examples.
- Week 2: chapter-wise PYQs in two sittings. Aim for accuracy first and speed second.
- Week 3: fix every error from your log and take a timed set of 25 mixed questions.
- Ongoing: revisit once a week and again before each mock test.
