    en.wikipedia.org/wiki/Friedrich_Wöhler

    Friedrich Wöhler. Friedrich Wöhler (German: [ˈvøːlɐ]) FRS (For) Hon FRSE (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. He was the first to prepare several inorganic compounds ...

  3. Organic chemistry - Wikipedia

    en.wikipedia.org/wiki/Organic_chemistry

    t. e. Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. [1] Study of structure determines their structural formula.

  4. Wöhler synthesis - Wikipedia

    en.wikipedia.org/wiki/Wöhler_synthesis

    Wöhler synthesis. The Wöhler synthesis is the conversion of ammonium cyanate into urea. 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 ...

  5. Organic synthesis - Wikipedia

    en.wikipedia.org/wiki/Organic_synthesis

    Organic synthesis is a branch of chemical synthesis concerned with the construction of organic compounds. Organic compounds are molecules consisting of combinations of covalently-linked hydrogen, carbon, oxygen, and nitrogen atoms. Within the general subject of organic synthesis, there are many different types of synthetic routes that can be ...

  7. Carboxylic acid - Wikipedia

    en.wikipedia.org/wiki/Carboxylic_acid

    Carboxylic acid. In organic chemistry, a carboxylic acid is an organic acid that contains a carboxyl group (−C (=O)−OH) [1] attached to an R-group. The general formula of a carboxylic acid is often written as R−COOH or R−CO2H, sometimes as R−C (O)OH with R referring to an organyl group (e.g., alkyl, alkenyl, aryl), or hydrogen, or ...

  8. Organolithium reagent - Wikipedia

    en.wikipedia.org/wiki/Organolithium_reagent

    Organolithium reagent. In organometallic chemistry, organolithium reagents are chemical compounds that contain carbon – lithium (C–Li) bonds. These reagents are important in organic synthesis, and are frequently used to transfer the organic group or the lithium atom to the substrates in synthetic steps, through nucleophilic addition or ...

  9. Organic compound - Wikipedia

    en.wikipedia.org/wiki/Organic_compound

    Some chemical authorities define an organic compound as a chemical compound that contains a carbon–hydrogen or carbon–carbon bond; others consider an organic compound to be any chemical compound that contains carbon. For example, carbon-containing compounds such as alkanes (e.g. methane CH4) and its derivatives are universally considered ...
