Carbon is a tetracovalent element, why


For the phenomenon that two or more compounds can have the same number and type of atoms and the same molecular weight, the term is Isomerism been coined. Isomers are the same Elemental composition and are represented by the same empirical formula. There are two main types of isomerism. The most common and important is as Structural isomerism known, which designation expresses that the differences between the isomers are due to the different arrangement in which the atoms are linked to one another. Let us recall the example of butane and isobutane; in the first the carbon atoms are arranged in an unbranched chain, in the second in a branched chain. Such structural isomers can be Skeletal isomers call. The concept of structural isomerism also includes the possibility that another element or a group of atoms can assume different positions in the molecule, as in the case of 1-chloro-propane and 2-chloro-propane. Such isomers will be Positional isomers called. In the case of compounds of more complex composition, there may be greater structural differences, so that different functional groups occur in the isomers, such as e.g. B. with dimethyl ether and ethyl alcohol. Structural isomers of this type would be as Functional isomers to call. Under the constitution A compound is understood to mean the arrangement in which the atoms are connected to one another; it is represented by a constitutional formula.

  5. Dominique François Jean Arago (1786-1853), French physicist who, after successfully completing the survey of Spain, was employed as an astronomer at the Royal French Observatory, a position he held until his death. He was actively involved in French politics and did much to raise the profile of French science.Google Scholar

  8. Kestner, owner of a chemical factory, had received an acid as a by-product in the production of tartaric acid, which he believed to be oxalic acid and sold it as such. In a handbook in 1819 it was indicated that this compound was neither oxalic acid nor tartaric acid. Gay-Lussac received a sample from Kestner, found the same analytical values ​​as for tartaric acid and called the new compound racemic acid. It was not until 1830 that Berzelius was convinced that both compounds had the same composition, and it was he who gave the name Isomeric for the apparition. Google Scholar
  9. John Frederick William Herschel (1792–1871), well-known English astronomer, who was more interested in chemistry and the properties of light and made valuable contributions in these areas.Google Scholar
  10. Jacobus Hendricus van’t Hoff (1852–1911), Dutch physical chemist, professor at the University of Amsterdam and, after 1896, at the Prussian Academy of Sciences and the University of Berlin. He is known not only for his theoretical contributions to stereochemistry, but also for his contributions to the theory of solutions and chemical equilibria. He was the first to receive the Nobel Prize in Chemistry in 1901.Google Scholar
  11. Jules Achille Le Bel (1847–1930), French chemist, was financially independent and carried out his research privately. His experimental work was mainly aimed at verifying predictions based on his stereochemical theories.Google Scholar

  14. In 1951 a general system for designating the asymmetric configuration was published, according to which each asymmetric center is classified as R. (lat. rectus) or 5 (lat. sinister) referred to as. This system was modified and expanded in 1956 to include optical isomers of axial and planar asymmetry.Google Scholar
  15. William Jackson Pope (1870–1939), professor at Cambridge University and one of the founders of the International Union of Chemistry. His early work on camphorsulphonic acid (p. 686) led him to its use for the cleavage of dihydropapaverine and later for the cleavage of optically active nitrogen, sulfur and selenium compounds. It was the first optically active compound that did not contain an asymmetric atom and the first active compound to contain only a single carbon atom. During the First World War he developed the process for the preparation of mustard gas from ethylene and sulfur monochloride (p. 302) .Google Scholar
