  2. Cyanamide - Wikipedia

    en.wikipedia.org/wiki/Cyanamide

    Cyanamide is the name for a functional group with the formula R 1 R 2 N−C≡N where R 1 and R 2 can be a variety of groups. These compounds are called cyanamides . One example is naphthylcyanamide, C 10 H 7 N(CH 3 )CN, which has been produced by the von Braun reaction , [ 19 ] a general method for the conversion of tertiary amines to ...

  3. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.

  4. Chemical graph generator - Wikipedia

    en.wikipedia.org/wiki/Chemical_graph_generator

    These fragments were then used as building blocks in the structure generator. This structure generator was part of a CASE system, ESESOC. [23] Breadth-first search generation. Molecular structure generation is explained step by step. Starting from a set of atoms, bonds are added between atom pairs until reaching saturated structures. A series ...

  5. Inorganic carbodiimide - Wikipedia

    en.wikipedia.org/wiki/Inorganic_carbodiimide

    The Lewis diagram for NCN 2-showing the symmetric carbodiimide form (1) and the asymmetric cyanamide form (2). Inorganic carbodiimides (or cyanamides depending on the NCN 2-form) design a family of compounds containing the carbodiimide (or cyanamide) anion NCN 2-bonded to an inorganic group such as a metal.

  6. Calcium carbide - Wikipedia

    en.wikipedia.org/wiki/Calcium_carbide

    Its main use industrially is in the production of acetylene and calcium cyanamide. [ 3 ] The pure material is colorless, while pieces of technical-grade calcium carbide are grey or brown and consist of about 80–85% of CaC 2 (the rest is CaO ( calcium oxide ), Ca 3 P 2 ( calcium phosphide ), CaS ( calcium sulfide ), Ca 3 N 2 ( calcium nitride ...

    Gilbert Newton Lewis ForMemRS [1] (October 23 [2] [3] [4] or October 25, 1875 – March 23, 1946) [1] [5] [6] was an American physical chemist and a dean of the college of chemistry at University of California, Berkeley.

  8. Linnett double-quartet theory - Wikipedia

    en.wikipedia.org/wiki/Linnett_Double-Quartet_Theory

    A key trait of LDQ theory that is shared with Lewis theory is the importance of using formal charges to determine the most important electronic structure. [19] LDQ theory produces the spatial distributions of the electrons by considering the two fundamental physical properties of said electrons:

  9. Radical (chemistry) - Wikipedia

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

    The hydroxyl radical, Lewis structure shown, contains one unpaired electron. Lewis dot structure of a Hydroxide ion compared to a hydroxyl radical. In chemistry, a radical, also known as a free radical, is an atom, molecule, or ion that has at least one unpaired valence electron.
