Werner called his new theory, "coordination theory".Chain Theory Proposed 1869 The supersession of the most successful pre-Werner theory of the structure of coordination compounds, the so-called Blomstrand-Jørgensen chain theory, by Alfred Werner's coordination theory constitutes a valuable case study in scientific method and the history of chemistry. He is considered one of the founders of coordination chemistry, and is known for the debates which he had with Alfred Werner during 1893-1899. While Jørgensen's theories on coordination chemistry were ultimately proven to be incorrect, his experimental work provided much of the basis for Werner's theories. The coordination theory is an abrupt break with both the Kekulé valence theory and the Blomstrand- Jørgensen chain theory.It assumes that the metal is bound to 6 atoms or groups, creating a radical. The remaining atoms or groups are loosely bound to this radical.

The disappointment came when the Blomstrand-Jørgensen chain theory could not predict the conductivity or the number of ions that would exist in aqueous solution or rationalize the correct number of isomers of certain compounds.

Specifically, IrCl3(NH3)3 was predicted by … To answer this question, Christian Blomstrand (1869) developed a “chain theory” of bonding for the cobalt ammine compounds, which was later adapted by his student, Sophus Jørgensen (1884). Drawing structures analogous to organic chemicals, they arrived at a cobalt metal bound to long chains of ammonia, with a chlorine at the end of each group.

he arranged the components in the form of chains. To the compound CoCl 2 · 6NH 3 for example he gave the following constitu-tional formula: It was however known even in Blomstrand’s day that in certain of these ad-dition compounds of ammonia and metal salts, the individual acid residues Jorgensen was a real controversy. It is important to realize that not all controversies are of the same kind. They may usefully be distinguished in controversies of fact, of theory and of principle.4 In a controversy of fact, scientists disagree about the experimental basis of Inorganic Chemistry - Inorganic chemistry is the Branch of chemistry which deals with the compounds outside the realms of organic chemistry. Inorganic Chemistry is one such discipline of science which is vibrating at high frequency under the impact of knowledge explosion.
