Coordination Compounds: Class 12 Chemistry (CBSE) important questions and practice
Coordination Compounds is chapter 5 of 10 in CBSE Class 12 Chemistry. Below are the topics the paper draws from, the question types that come up again and again, and a free practice test on this chapter alone.
Topics in this chapter
- Werner's theory and terminology: ligand, coordination number, denticity, chelate
- IUPAC nomenclature of coordination compounds
- Isomerism: structural (ionisation, linkage, hydrate, coordination) and stereo (geometrical, optical)
- Valence Bond Theory: hybridisation, inner and outer orbital complexes, magnetic behaviour
- Crystal Field Theory: splitting in octahedral and tetrahedral fields, spectrochemical series, colour
- Bonding in metal carbonyls and applications of coordination compounds
What examiners usually ask
- Write the IUPAC name of [Co(NH3)5Cl]Cl2 and [Pt(NH3)2Cl2]; draw the geometrical isomers of the latter
- Using Valence Bond Theory explain why [Fe(CN)6]4- is diamagnetic while [FeF6]3- is paramagnetic
- Explain crystal field splitting in an octahedral field and why [Ti(H2O)6]3+ is coloured
Exam tip
Hybridisation plus magnetic behaviour (d2sp3 inner orbital, low spin versus sp3d2 outer orbital, high spin) is a certain 3-mark question; also practise naming with ligand alphabetical order and the metal's oxidation state in Roman numerals.
