  2. Carbanion - Wikipedia

    en.wikipedia.org/wiki/Carbanion

    Formally, a carbanion is the conjugate base of a carbon acid: R 3 CH + B − → R 3 C − + HB. where B stands for the base. The carbanions formed from deprotonation of alkanes (at an sp 3 carbon), alkenes (at an sp 2 carbon), arenes (at an sp 2 carbon), and alkynes (at an sp carbon) are known as alkyl, alkenyl , aryl, and alkynyl anions ...

  4. Catenation - Wikipedia

    en.wikipedia.org/wiki/Catenation

    Nitrogen, unlike its neighbor carbon, is much less likely to form chains that are stable at room temperature. But, there do exist nitrogen chains; for example, in solid nitrogen, triazane, azide anion and triazoles. [12] [13] Longer series with eight or more nitrogen atoms, such as 1,1'-Azobis-1,2,3-triazole, have been synthesized. These ...

  5. Valence (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Valence_(chemistry)

    The valence is the combining capacity of an atom of a given element, determined by the number of hydrogen atoms that it combines with. In methane, carbon has a valence of 4; in ammonia, nitrogen has a valence of 3; in water, oxygen has a valence of 2; and in hydrogen chloride, chlorine has a valence of 1.

  6. Ring (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Ring_(chemistry)

    Four cycloalkanes, all of which exhibit simple rings. In chemistry, a ring is an ambiguous term referring either to a simple cycle of atoms and bonds in a molecule or to a connected set of atoms and bonds in which every atom and bond is a member of a cycle (also called a ring system).

  7. Triphenylcarbenium - Wikipedia

    en.wikipedia.org/wiki/Triphenylcarbenium

    Triphenylcarbenium Space-filling model of the Ph 3 C + ion. In chemistry, triphenylcarbenium, [1] triphenylmethyl cation, tritylium , [2] or trityl cation is an ion with formula [C 19 H 15] + or (C 6 H 5) 3 C +, consisting of a carbon atom with a positive charge connected to three phenyl groups. It is a charged version of the triphenylmethyl ...

  8. Three-carbon molecule - Wikipedia

    en.wikipedia.org/wiki/Three-carbon_molecule

    Three-carbon molecules are based on a skeleton made from three carbon atoms. They may be in a chain, or cycles. C3 hydrocarbons are usually gases, they are inflammable, and may be harmful to humans and the environment. [1] The CAS registry number for three-carbon hydrocarbons is 68606-26-8. Hydrocarbons that include three atoms are: Propane C 3 ...

  9. Oxidation state - Wikipedia

    en.wikipedia.org/wiki/Oxidation_state

    In chemistry, the oxidation state, or oxidation number, is the hypothetical charge of an atom if all of its bonds to other atoms were fully ionic.It describes the degree of oxidation (loss of electrons) of an atom in a chemical compound.
