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.

Weisstein 2021-04-16 · Blomstrand proposed that ammonia molecules could link together as ―NH 3 ― chains, similar to ―CH 2 ― chains in hydrocarbons.

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 Introducción a la química de los elementos de transición.

Chain theory was popular for many years after it was proposed in 1869 by Blomstrand.

In addition to his strictly chemical work, he characterized and analyzed many minerals, especially those of the rarer elements or of unknown composition, such as monazite, ilmenite, tantalite, niobite, and euxenite. They also recognised that supply chain theory suggests that the chain should be managed from “end-to-end” but noted that “our research found very few examples of this” (p. 763). This focus on end-to-end thinking is instructive given that integration of supply chain processes and information is a central tenet of contemporary SCM thinking.
Blomstrand and his student Jorgensen used Cobalt (iii), and they suggested that Cobalt (iii) has only three bonds, hence in order to explain the extra six ammonia compounds in the complex CoCl3.6NH3 they used the chain theorem, with its structure looking like this:

His interpretations of the l?teo, purpureo, roseo, praseo, violeo, croceo, flavo, and other series of complex salts were made in the light of his extensions and modifications of Blomstrand's chain theory.

TEORI RANTAI BLOMSTRAND-JORGENSEN. 1869 Blomstrand (Swedia) mengajukan teori rantai untuk struktur kompleks logam. Karena tiap-tiap unsur mempunyai valensi yang tetap, maka Blomstrand dan Jorgensen mengatakan bahwa : Dalam kompleks kobal (III) hanya ada tiga ikatan. Oleh karena itu, maka dapat digambarkan struktur dari kompleks-kompleks :

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.
