NCERT Class 12 Chemistry Chapter 5 Coordination Compounds Solutions
1. Explain the bonding in coordination compounds in terms of Werner’s postulates.
2. FeSO4 solution mixed with (NH4)2SO4 solution in 1:1 molar ratio gives the test of Fe2+ ion but CuSO4 solution mixed with aqueous ammonia in 1:4 molar ratio does not give the test of Cu2+ ion. Explain why?
3. Explain with two examples of each of the following: coordination entity, ligand, coordination number, coordination polyhedron, homoleptic and heteroleptic.
4. What is meant by unidentate, bidentate and ambidentate ligands? Give two examples for each.
5. Using IUPAC norms write the formulas for the following:
i) Tetrahydroxidozincate(II)
ii) Potassium tetrachloridopalladate(II)
iii) Diamminedichloridoplatinum(II)

5. List various types of isomerism possible for coordination compounds, giving an example of each.
6. Aqueous copper sulphate solution (blue) gives:
(i) a green precipitate with aqueous potassium fluoride and
(ii) a bright green solution with aqueous potassium chloride. Explain these experimental results.
7. What is the coordination entity formed when an excess of aqueous KCN is added to an aqueous solution of copper sulphate?
8. Why is it that no precipitate of copper sulphide is obtained when H2S(g) is passed through this solution?
