Friedrich Wöhler (German:) FRS(For) HonFRSE (31 July 1800 – 23 September 1882) was a German chemist known for his work in both organic and inorganic chemistry, being the first to isolate the chemical elements beryllium and yttrium in pure metallic form.
This chemical reaction was described in 1828 by Friedrich Wöhler. [1] It is often cited as the starting point of modern organic chemistry. Although the Wöhler reaction concerns the conversion of ammonium cyanate, this salt appears only as an (unstable) intermediate.
Radical theory is an obsolete scientific theory in chemistry describing the structure of organic compounds.The theory was pioneered by Justus von Liebig, Friedrich Wöhler and Auguste Laurent around 1830 and is not related to the modern understanding of free radicals.
In 1827, Friedrich Wöhler refined a process discovered by Hans Christian Ørsted, a Danish chemist, who first produced impure aluminium in 1825. With the newly made Al metal, he established the specific gravity of aluminium in 1845.
Justus Liebig's Annalen der Chemie (often cited as Liebigs Annalen) was one of the oldest and historically most important journals in the field of organic chemistry worldwide. It was established in 1832 and edited by Justus von Liebig with Friedrich Wöhler and others until Liebig's death in 1873.
In organic chemistry, the benzoin addition is an addition reaction involving two aldehydes (−CH=O). The reaction generally occurs between aromatic aldehydes or glyoxals (OCH=CHO), [1] [2] and results in formation of an acyloin (−C(O)CH(OH)−). In the classic example, benzaldehyde is converted to benzoin (PhCH(OH)C(O)Ph). [3]
In the 17th century, modern science responded to Newton's action at a distance and the mechanism of Cartesian dualism with vitalist theories: that whereas the chemical transformations undergone by non-living substances are reversible, so-called "organic" matter is permanently altered by chemical transformations (such as cooking).
Fittig studied chemistry at the University of Göttingen, graduating as Ph.D. with a dissertation on acetone in 1858, under the supervision of Heinrich Limpricht and Friedrich Wöhler. [citation needed] He subsequently held several appointments at Göttingen, becoming Wöhler's assistant in 1858, privatdozent in 1860 and extraordinary professor ...
