What did Friedrich Kekule discover?
Kekule is regarded as one of the principal founders of modern organic chemistry, the chemistry of carbon-based compounds. In 1858 he showed that carbon can link with itself to form long chains. In 1865 he reported his discovery of the benzene ring as the basis for another major group of carbon molecules.
What are the contribution of Friedrich Wohler?
Wöhler is known for seminal contributions in organic chemistry, in particular the Wöhler synthesis of urea. His synthesis of the organic compound urea in the laboratory from inorganic precursors refuted the prevailing belief that organic compounds could only be produced by living organisms due to a “life force”.
What is the contribution of August Kekule?
Contributions and Achievements. Kekulé was the principal founder of the theory of chemical structure, which he announced in two articles published in 1857 and 1858. He proposed that carbon was tetravalent (valence of four) and that one of the four bonds of the carbon atom could be used to join with another carbon atom.
How did August Kekule discovery change chemistry?
How did August Kekule’s discovery about carbon change the science of chemistry? August Kekule established a simple formula to represent how chemicals bonded. Kekule realized that its six carbon atoms formed a ring (not a chain), and each one had a hydrogen atom attached with alternating single and double bonds.

What was Friedrich Wohler trying to produce?
Friedrich Wöhler was the first to synthesize an organic compound from an inorganic substance. In 1828, he synthesized urea by slowly evaporating a water solution of ammonium cyanate, which he had prepared by adding silver cyanate to ammonium chloride.
Is Kekule a Nobel Prize winner?
Of the first five Nobel Prizes in Chemistry, Kekulé’s former students won three: van ‘t Hoff in 1901, Fischer in 1902 and Baeyer in 1905. A larger-than-life monument of Kekulé, unveiled in 1903, is situated in front of the former Chemical Institute (completed 1868) at the University of Bonn.
What elements was Friedrich August Kekule highly interested in?
One element that he was highly interested in was carbon, a chemical element that is nonmetal. He described that carbon could link into long chains that would form shapes. Because of his discoveries of the different shapes of carbon, he often stated ”We define organic chemistry as the chemistry of carbon compounds.
What are Kekule structures?
Kekulé was the first to suggest a sensible structure for benzene. The carbons are arranged in a hexagon, and he suggested alternating double and single bonds between them. Each carbon atom has a hydrogen attached to it. This diagram is often simplified by leaving out all the carbon and hydrogen atoms!
How did Kekule discovered the structure of benzene?
German chemist August Kekulé visualized the ring structure of benzene in 1865. Most organic chemical compounds contain loops of six carbon atoms called benzene rings. The nineteenth-century German chemist August Kekulé claimed to have pictured the ring structure of benzene after dreaming of a snake eating its own tail.
