  2. Organic chemistry - Wikipedia

    en.wikipedia.org/wiki/Organic_chemistry

    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]

  3. Carbyne - Wikipedia

    en.wikipedia.org/wiki/Carbyne

    In organic chemistry, a carbyne is a general term for any compound whose structure consists of an electrically neutral carbon atom connected by a single covalent bond and has three non-bonded electrons. [1] The carbon atom has either one or three unpaired electrons, depending on its excitation state; making it a radical.

  4. Functional group - Wikipedia

    en.wikipedia.org/wiki/Functional_group

    In organic chemistry, a functional group is a substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions. The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition.

    The second part contains 8 free response questions. Complete written explanations and calculations are required for full credit on a question, and partial credit is awarded. More thorough knowledge of basic theories is required, and often there are questions on less-emphasized portions of normal high school chemistry curricula, such as organic ...

    en.wikipedia.org/wiki/Outline_of_organic_chemistry

    The following outline is provided as an overview of and topical guide to organic chemistry: . Organic chemistry is the scientific study of the structure, properties, composition, reactions, and preparation (by synthesis or by other means) of carbon-based compounds, hydrocarbons, and their derivatives.

  7. Acyl group - Wikipedia

    en.wikipedia.org/wiki/Acyl_group

    In chemistry, an acyl group is a moiety derived by the removal of one or more hydroxyl groups from an oxoacid, [1] including inorganic acids. It contains a double-bonded oxygen atom and an organyl group ( R−C=O ) or hydrogen in the case of formyl group ( H−C=O ).

  8. Cross-coupling reaction - Wikipedia

    en.wikipedia.org/wiki/Cross-coupling_reaction

    The leaving group X in the organic partner is usually a halide, although triflate, tosylate, pivalate esters, and other pseudohalides have been used. [15] Chloride is an ideal group due to the low cost of organochlorine compounds. Frequently, however, C–Cl bonds are too inert, and bromide or iodide leaving groups are required for acceptable ...

  9. Organic reaction - Wikipedia

    en.wikipedia.org/wiki/Organic_reaction

    Organic chemistry has a strong tradition of naming a specific reaction to its inventor or inventors and a long list of so-called named reactions exists, conservatively estimated at 1000. A very old named reaction is the Claisen rearrangement (1912) and a recent named reaction is the Bingel reaction (1993).
