What is Alfred Werner theory?
Werner’s theory states that- 1. Metals possess two types of valencies called primary / ionizable and secondary / non – ionizable valency. 2. Every metal atom has a tendency to satisfy both its primary and secondary valencies.
Who is called the father of coordination chemistry?
Alfred Werner defined the basics of coordination chemistry, work for which he was awarded the Nobel Prize in chemistry in 1913.
Why did Werner get the Nobel Prize?
The Nobel Prize in Chemistry 1913 was awarded to Alfred Werner “in recognition of his work on the linkage of atoms in molecules by which he has thrown new light on earlier investigations and opened up new fields of research especially in inorganic chemistry.”
What are Werner complexes?
Werner complexes have inspired the coordination chemistry of metal ions with organic ligands in the molecular realm giving rise to bioinorganic, organometallic, and cluster chemistry. This has brought a new level of control over the geometric and electronic properties of molecules.
How did Alfred Werner arrange the periodic table?
Although today it is known that electronic configuration is the under-lying basis for chemical periodicity and the periodic system, Werner (in 1905), relying only on intuition, his vast knowledge of chemistry, and his recognition of analogies among elements, devised a “long form” of the Periodic Table, in which the …
What are limitations of Warner’s theory?
Limitations of Werner’s Theory It fails to explain the magnetic, colour and optical properties shown by coordination compounds. It failed to explain the reason why all elements don’t form coordination compounds. It failed to explain the directional properties of bonds in coordination compounds.
Why was the Werner theory developed?
What is Werner’s Theory? In 1823, Werner put forth this theory to describe the structure and formation of complex compounds or coordination compounds. It is because of this theory that he got the Nobel prize and is known as the father of coordination chemistry.
How old is organic chemistry?
Organic chemistry was first defined as a branch of modern science in the early 1800’s by Jon Jacob Berzelius. He classified chemical compounds into two main groups: organic if they originated in living or once-living matter and inorganic if they came from “mineral” or non-living matter.

How was Werner able to show that the only geometry possible for a complex with coordination number 6 is octahedral?
In the case of several other complexes in which the coordination number of the central atom was six, werner was able to conclude that in all these cases the six coordinated complex have octahedral geometry. He studied the geometry of the complexes in which the coordination number of the central metal atom is 4.
How Werner theory explained in the view of electronic theory of Valency?
The important postulates of Werner’s theory are: The central metal or the metal atoms in coordination compounds show two types of valency. They are the primary and secondary valency. The primary valency relates to the oxidation state and the secondary valency relates to the coordinate number.
Who is Alfred Werner?
A Swiss chemist and winner of the Nobel Prize for Chemistry in 1913 for his research into the structure of coordination compounds, Alfred Werner was born on 12 December 1866 in Mulhouse, Alsace (which was then part of France, but which was annexed by Germany in 1871). Werner developed the basis for modern coordination chemistry.
What did Alfred Werner contribute to the atomic theory?
In 1893 Alfred Werner contributed to the understanding of molecular structures of inorganic substances – chemical compounds that do not contain carbon. According to Alfred Werner, the attractive forces are not connected to certain directions in the atom but emanate uniformly from the middle of the atom.
What is Alfred Werner’s Nobel Prize in Chemistry?
Alfred Werner’s Nobel Prize is the first to be awarded in the field of inorganic chemistry. It was also the first time the prize in Chemistry was awarded to a Swiss national.
How was Werner’s theory verified?
At the time of its inception, Werner’s theory was largely without experimental verification. He had done no work in the field, and the data that he cited in support of his ideas had been obtained by others, especially by his primary scientific adversary, the Danish chemist Sophus Mads Jørgensen.
