  2. Dichloromethane - Wikipedia

    en.wikipedia.org/wiki/Dichloromethane

    The chemical compound's low boiling point allows the chemical to function in a heat engine that can extract mechanical energy from small temperature differences. An example of a DCM heat engine is the drinking bird. The toy works at room temperature. [17]

  3. Geminal - Wikipedia

    en.wikipedia.org/wiki/Geminal

    In chemistry, the descriptor geminal (from Latin gemini 'twins' [1]) refers to the relationship between two atoms or functional groups that are attached to the same atom. A geminal diol, for example, is a diol (a molecule that has two alcohol functional groups) attached to the same carbon atom, as in methanediol.

  4. Methyl group - Wikipedia

    en.wikipedia.org/wiki/Methyl_group

    The oxidation products derived from methyl are hydroxymethyl group −CH 2 OH, formyl group −CHO, and carboxyl group −COOH. For example, permanganate often converts a methyl group to a carboxyl (−COOH) group, e.g. the conversion of toluene to benzoic acid. Ultimately oxidation of methyl groups gives protons and carbon dioxide, as seen in ...

  5. Dichloroacetic acid - Wikipedia

    en.wikipedia.org/wiki/Dichloroacetic_acid

    Dichloroacetic acid (DCA), sometimes called bichloroacetic acid (BCA), is the organic compound with formula CHCl 2 CO 2 H.It is an analogue of acetic acid, in which 2 of the 3 hydrogen atoms of the methyl group have been replaced by chlorine atoms.

  6. Paraquat - Wikipedia

    en.wikipedia.org/wiki/Paraquat

    Paraquat (trivial name; / ˈ p ær ə k w ɒ t /), or N,N′-dimethyl-4,4′-bipyridinium dichloride (systematic name), also known as methyl viologen, is a toxic organic compound with the chemical formula [(C 6 H 7 N) 2]Cl 2. It is classified as a viologen, a family of redox-active heterocycles of similar structure. [5]

  7. Methanesulfonyl chloride - Wikipedia

    en.wikipedia.org/wiki/Methanesulfonyl_chloride

    Methanesulfonyl chloride is mainly used to give methanesulfonates by its reaction with alcohols in the presence of a non-nucleophilic base. [8] In contrast to the formation of toluenesulfonates from alcohols and p-toluenesulfonyl chloride in the presence of pyridine, the formation of methanesulfonates is believed to proceed via a mechanism wherein methanesulfonyl chloride first undergoes an ...

  8. Methylene bridge - Wikipedia

    en.wikipedia.org/wiki/Methylene_bridge

    The methylene bridge (methanediyl group) In organic chemistry, a methylene bridge, methylene spacer, or methanediyl group is any part of a molecule with formula −CH 2 −; namely, a carbon atom bound to two hydrogen atoms and connected by single bonds to two other distinct atoms in the rest of the molecule.

  9. Methylphosphonyl dichloride - Wikipedia

    en.wikipedia.org/wiki/Methylphosphonyl_dichloride

    Methylphosphonyl dichloride (DC) or dichloro is an organophosphorus compound. It has commercial application in oligonucleotide synthesis, [ 1 ] but is most notable as being a precursor to several chemical weapons agents.
