| Werner’s Theory of Coordination Compounds |
General introduction to salts, difference between double salt and coordination (complex salt) compound with respect to their ionization in water, with an example.
Werner’s theory – postulates, limitations. |
| Definitions of Some Important Terms Pretending to Coordination Compounds |
Coordination entity, central metal ion, coordination number, coordination sphere, oxidation state of central metal ion, homoleptic and heteroleptic complexes, examples. |
| Nomenclature of Coordination Compounds |
Nomenclature of coordination compounds – mononuclear compounds. |
| Isomerism in Coordination Compounds |
Isomerism: Structural – linkage, ionization, solvate, coordination – definition and examples. Stereoisomerism – geometrical and optical, examples, facial and meridional as geometrical isomers- example. |
| Bonding in Coordination Compounds |
VBT: salient features, application of VBT for the formation of – [CoF6] 3, [Co (NH3)6] 3+, [NiCl4] 2, [Ni (CN)4] 2.
magnetic properties – low spin and high spin complexes with examples, limitations of VBT.
CFT (crystal field theory): crystal field splitting-meaning, crystal field splitting in octahedral and tetrahedral coordination entities using energy level diagram and their comparison. Spectrochemical series, compare weak field ligand – strong field ligand with respect to d4 ions in octahedral field (0 < P, 0 > P). Explanation for colour of complexes using CFT, examples. |

Bonding in Metal Carbonyls |
| Stability of Coordination Compounds |
Stability of Coordination Compounds |
| Importance and Applications of Coordination Compounds |
In biological systems, qualitative analysis, extraction of metals, examples. |
