  2. Dichloromethane - Wikipedia

    en.wikipedia.org/wiki/Dichloromethane

    DCM is produced by treating either chloromethane or methane with chlorine gas at 400–500 °C. At these temperatures, both methane and chloromethane undergo a series of reactions producing progressively more chlorinated products.

  3. Methylene group - Wikipedia

    en.wikipedia.org/wiki/Methylene_group

    A methylene group is any part of a molecule that consists of two hydrogen atoms bound to a carbon atom, which is connected to the remainder of the molecule by two single bonds. [1] The group may be represented as −CH 2 − or >CH 2 , where the '>' denotes the two bonds.

  4. A value - Wikipedia

    en.wikipedia.org/wiki/A_value

    In general, the larger a substituent's A-value, the larger the steric effect of that substituent. A methyl group has an A-value of 1.74 while tert-butyl group has an A-value of ~5. Because the A-value of tert-butyl is higher, tert-butyl has a larger steric effect than methyl. This difference in steric effects can be used to help predict ...

  5. 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 ...

  6. Methyldichlorophosphine - Wikipedia

    en.wikipedia.org/wiki/Methyldichlorophosphine

    Methyldichlorophosphine belongs to the group of halophosphines, some of which are used as intermediates in the production of plant protection agents, stabilizers for plastics, and catalysts. It is a precursor of the herbicide Glufosinate. It is also used in the production of flameproofing compounds. [4]

  7. Alkylidene group - Wikipedia

    en.wikipedia.org/wiki/Alkylidene_group

    In organic chemistry, alkylidene is a general term for divalent functional groups of the form R 2 C=, where each R is an alkane or hydrogen. [1] They can be considered the functional group corresponding to mono- or disubstituted divalent carbenes (known as alkylidenes), [2] or as the result of removing two hydrogen atoms from the same carbon atom in an alkane.

  8. Dimethyldichlorosilane - Wikipedia

    en.wikipedia.org/wiki/Dimethyldichlorosilane

    Methyl chloride is then passed through the reactor to produce mainly dimethyldichlorosilane. 2 CH 3 Cl + Si ( CH 3 ) 2 SiCl 2 {\displaystyle {\ce {2 CH3Cl + Si -> (CH3)2SiCl2}}} The mechanism of the direct synthesis is not known.

  9. Methylene bridge - Wikipedia

    en.wikipedia.org/wiki/Methylene_bridge

    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.
