Course content

1 section • 12 lectures • 2h 48m total length

9.1. Contents to Coordination Compounds11:16
Explore the contents of coordination compounds, including structure, ligands, isomers, naming, crystal field, color and magnetism, with applications in analytical chemistry, metallurgy, water treatment, and catalysis.
9.2. Werner's Theory17:53
Discover Werner's theory of coordination compounds, distinguishing primary and secondary valences, and see how cobalt chloride ammonia complexes form octahedral structures with color changes as ligands vary.
9.3. Important Terms10:25
Explore the key terms of coordination compounds, including coordination complexes and complex ions, donor atoms and ligands, coordination number, and coordination sphere, with examples like [Ni(NH3)6]2+.
9.4. Nomenclature of Co-ordination Compounds19:02
Learn the nomenclature of coordination compounds by applying rules for naming the coordination sphere, ligand types, oxidation states, and alphabetical ordering.
9.5. Isomerism in Co-ordination Compounds6:45
Explore isomerism in coordination compounds, identifying ionization, hydration, linkage, and coordination isomers, and distinguish structural, geometrical, and optical isomers through ligand arrangements.
9.6. Stereo isomers10:58
Explore stereo isomers in coordination compounds, distinguishing geometrical and optical forms, and see how four- and six-coordinate geometries, including square planar and octahedral structures, influence isomerism and optical activity.
9.7. Bonding of Co-ordination Compounds15:01
Explore how coordination compounds bond differently from general chemistry, using hybridization and modern theories—Willis Bourne theory, crystal field theory, and molecular orbital theory—to explain color, geometry, and magnetic properties.
9.8. Tetrahedral complexes10:25
Explore tetrahedral coordination complexes, exemplified by Ni(CO)4, covering sp3 hybridization, electron pairing, and donor CO ligands, and highlight valence bond theory's limits in explaining spectra and magnetism.
9.9. Crystal Field Theory28:28
Discover how crystal field theory treats metal–ligand electrostatic interactions, splits d orbitals into two energy sets in octahedral and tetrahedral fields, and explains high-spin and low-spin configurations.
9.10. Colour and Magnetism of Co-ordination Compounds11:30
Explore how color and magnetism arise in coordination compounds through crystal field theory, ligand effects, and electronic transitions, including paramagnetism and color changes with hydration.
9.11. Stability of Coordination Compounds in Solution11:47
Explore the stability of coordination compounds in solution by examining formation constants, overall stability, thermodynamic and kinetic stability, and how metal–ligand interactions govern complex persistence.
9.12. Applications of Coordination Compounds14:48
Explore the wide range of applications of coordination compounds in analytical chemistry, metallurgy, water treatment, electroplating, photography, medicine, biology, and plant and metal carbonate chemistry.

Requirements

The child should have clear concepts of Co-ordination Compounds and their derivative's.

Description

Werner, the son of a factory worker, was born in Alsace. He developed an

interest in chemistry at an early age, and he did his first independent research experiments at age 18. While doing his military service in southern Germany, he attended a series of chemistry lectures, and he subsequently received his PhD at the University of Zurich in Switzerland, where he was appointed professor of chemistry at age 29. He won the Nobel Prize in Chemistry in 1913 for his work on coordination compounds, which he performed as a graduate student and first presented at age 26. Apparently, Werner was so obsessed with solving the riddle of the structure of coordination compounds that his brain continued to work on the problem even while he was asleep. In 1891, when he was only 25, he woke up in the middle of the night and, in only a few hours, had laid the foundation for modern coordination chemistry.

Double salts are molecular compounds formed by the combination of two or more stable compounds in stoichiometric ratio. They exist only in crystal lattices but break down into their constituent compounds when dissolved in water or any other solvent. Their physical and chemical properties remain essentially the same as those of the individual compounds.

Coordination compounds are also formed by the combination of two or more stable compounds in stoichiometric ratio. They retain their identities even when dissolved in water or any other solvent and their properties are completely different from those of the constituents.
