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.

1. Original Works. Blomstrand had suggested that ammonia molecules could be linked together as -NH 3 - chains, analogous to -CH 2 - chains in hydrocarbons (Figure 3).[10] This description remained un-challenged until Werners publication in 1893. [6] Werner rejected the formally pentavalent nitrogen in Blomstrands chain formulas and abandoned Kekuls con- That is an atom of oxygen which often combines with two other atoms of a second from CHEM 311 at University of Wisconsin was predicted by the chain theory to have two precipitatable chlorides and a nonzero conductivity. In fact this compound did not form ions in solution and therefore its aqueous solution was a nonconductor and had no precipitatable chlorides. 2006-01-01 Thatscience-guy is an educational website that is based on inventions and the up coming inventions that are based on science and psychology.

Blomstrand and his student Jörgensen suggested there could be only three bonds to cobalt (III) in its complexes 5. 6. He attempted to reconcile the dualistic theory of Jöns Jacob Berzelius with unitary and type theories. Blomstrand developed the most widely accepted of the 19th century theories of coordination complexes. His chain theory (1869) was further developed, modified, and experimentally supported by his colleague Sophus Mads Jørgensen.

… (1869) of the Swedish chemist Christian Wilhelm Blomstrand, as modified and developed by the Danish chemist Sophus Mads Jørgensen. Jørgensen’s extensive preparations of numerous complexes provided the experimental foundation not only for the Blomstrand-Jørgensen chain theory but for Alsatian-born Swiss chemist Alfred Werner’s coordination theory (1893) as well. most successful and widely accepted of such theories was the so-called chain theory proposed in 1869 by Christian Wilhelm Blomstrand and modified in the 1880s and 1890s by Sophus Mads J0rgensen, the Danish chemist who was destined to become Werner's primary scientific adversary. This article briefly outlines Blomstrand's life and considers his best known book, Die Chemie der Jetztzeit (1869), as well as his work on mineralogy, inorganic chemistry (the earth acid elements, heteropoly acids, platinum complexes), and his theoretical views on valency, diazo compounds, and metal-ammines. His so-called ‘chain theory’, as developed and modified by his fellow Scandinavian chemist and close friend, Sophus Mads Jørgensen, was for more than three decades the most popular 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).
