  2. Chloroacetonitrile - Wikipedia

    en.wikipedia.org/wiki/Chloroacetonitrile

    The compound is an alkylating agent, [2] and as such is handled cautiously. Chloroacetonitrile is also generated in situ by the reaction of acetonitrile with sulfur monochloride . A second chlorination gives dichloro acetonitrile , which undergoes cycloaddition with sulfur monochloride to give 4,5-dichloro-1,2,3-dithiazolium chloride : [ 3 ]

  3. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    [1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [ 4 ] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.

  4. Acetonitrile - Wikipedia

    en.wikipedia.org/wiki/Acetonitrile

    Acetonitrile, often abbreviated MeCN (methyl cyanide), is the chemical compound with the formula CH 3 CN and structure H 3 C−C≡N. This colourless liquid is the simplest organic nitrile (hydrogen cyanide is a simpler nitrile, but the cyanide anion is not classed as organic). It is produced mainly as a byproduct of acrylonitrile manufacture.

  5. Structural formula - Wikipedia

    en.wikipedia.org/wiki/Structural_formula

    Lewis structures (or "Lewis dot structures") are flat graphical formulas that show atom connectivity and lone pair or unpaired electrons, but not three-dimensional structure. This notation is mostly used for small molecules. Each line represents the two electrons of a single bond. Two or three parallel lines between pairs of atoms represent ...

  6. Transition metal nitrile complexes - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_nitrile...

    Portion of the structure of the tetrachlorozincate (ZnCl 4 2−) salt of [Ni(MeCN) 6] 2+ [5] For the synthesis of some acetonitrile complexes, the nitrile serves as a reductant. This method is illustrated by the conversion of molybdenum pentachloride to the molybdenum(IV) complex: [6] 2 MoCl 5 + 5 CH 3 CN2 MoCl 4 (CH 3 CN) 2 + ClCH 2 CN + HCl

  7. Acetamide - Wikipedia

    en.wikipedia.org/wiki/Acetamide

    Acetamide (systematic name: ethanamide) is an organic compound with the formula CH 3 CONH 2. It is an amide derived from ammonia and acetic acid . It finds some use as a plasticizer and as an industrial solvent. [ 5 ]

    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.

  9. Lone pair - Wikipedia

    en.wikipedia.org/wiki/Lone_pair

    Lone pairs (shown as pairs of dots) in the Lewis structure of hydroxide. In chemistry, a lone pair refers to a pair of valence electrons that are not shared with another atom in a covalent bond [1] and is sometimes called an unshared pair or non-bonding pair.
