In chemistry, methylene is a divalent functional group CH2 derived formally from methane. The name "methylene" is used for two types of groups: In ecology functional groups are collections of organisms based on morphological, physiological, behavioral, biochemical, or environmental responses or on trophic criteria. ... The simplest hydrocarbon, methane, is a gas with a chemical formula of CH4. ...
-CH2- group (bound by two single bonds) present e.g. in dichloromethane (alternative name is methylene chloride)
=CH2 group (bound by one double bond), present e.g. in formaldehyde (can be named methylene oxide, but it is not used/recommended). The better example is methylenecyclopropene.
Methylene is also a name for Covalently bonded hydrogen and carbon in a molecule of methane. ... Dichloromethane or Methylene chloride is a chemical compound widely used as a solvent for organic materials. ... Covalently bonded hydrogen and carbon in a molecule of methane. ... The chemical compound formaldehyde (also known as methanal), is a gas with a strong pungent smell. ... Categories: Stub | Hydrocarbons ...
unstable electrically neutral species :CH2, the simplest carbene.
In chemistry a carbene is a short-lived and highly reactive organic molecule with a divalent carbon atom with only 6 valence electrons and the general formula: R1R2C:. The carbon atom is sp2 hybridised with a empty p-orbital extending above and below a plane containing R1 and R2 and...
Methylene Blue, methylthionine chloride or 3,7-bis(dimethylamino)phenothiazin-5-ium chloride is a chemical compound used as a dye and medication for Gram's stain, Wright's stain, and Jenner's stain and the treatment of methemoglobinemia.
Methylene Blue is also used in aquaculture, particularly by tropical fish hobbyists, as a treatment for ich (Ichthyophthirius multifilis).
Methylene Blue should not be confused with another histology stain methyl blue.
