  2. 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.

  3. 2-Chloroethanol - Wikipedia

    en.wikipedia.org/wiki/2-Chloroethanol

    2-Chloroethanol is toxic with an LD 50 of 89 mg/kg in rats. Like most organochlorine compounds, chloroethanol releases hydrochloric acid and phosgene when burned.. In regards to dermal exposure to 2-chloroethanol, the Occupational Safety and Health Administration has set a permissible exposure limit of 5 ppm (16 mg/m 3) over an eight-hour time-weighted average, while the National Institute for ...

  4. Dichloromethane - Wikipedia

    en.wikipedia.org/wiki/Dichloromethane

    [12] CH 4 + Cl 2 → CH 3 Cl + HCl CH 3 Cl + Cl 2CH 2 Cl 2 + HCl CH 2 Cl 2 + Cl 2 → CHCl 3 + HCl CHCl 3 + Cl 2 → CCl 4 + HCl. The output of these processes is a mixture of chloromethane, dichloromethane, chloroform, and carbon tetrachloride as well as hydrogen chloride as a byproduct. These compounds are separated by distillation.

  7. Chloroethane - Wikipedia

    en.wikipedia.org/wiki/Chloroethane

    Chloroethane is produced by hydrochlorination of ethylene: [11]. C 2 H 4 + HCl → C 2 H 5 Cl. At various times in the past, chloroethane has also been produced from ethanol and hydrochloric acid, from ethane and chlorine, or from ethanol and phosphorus trichloride, but these routes are no longer economical.

  8. Chemical structure - Wikipedia

    en.wikipedia.org/wiki/Chemical_structure

    A chemical structure of a molecule is a spatial arrangement of its atoms and their chemical bonds. Its determination includes a chemist 's specifying the molecular geometry and, when feasible and necessary, the electronic structure of the target molecule or other solid.

  9. Chloromethyl group - Wikipedia

    en.wikipedia.org/wiki/Chloromethyl_group

    Structure of the chloromethyl group. In organic chemistry, the chloromethyl group is a functional group that has the chemical formula −CH 2 −Cl. The naming of this group is derived from the methyl group (which has the formula −CH 3), by replacing one hydrogen atom by a chlorine atom. Compounds with this group are a subclass of the ...
