Diazonium compounds or diazonium salts are a group of organic compounds sharing a common functional group [R−N + ≡N]X − where R can be any organic group, such as an alkyl or an aryl, and X is an inorganic or organic anion, such as a halide. The parent compound where R is hydrogen, is diazenylium.
Biphenyl (also known as diphenyl, phenylbenzene, 1,1′-biphenyl, lemonene [4] or BP) is an organic compound that forms colorless crystals. Particularly in older literature, compounds containing the functional group consisting of biphenyl less one hydrogen (the site at which it is attached) may use the prefixes xenyl or diphenylyl.
The tetrafluoroborate can be obtained from crude benzenediazonium chloride by salt metathesis using tetrafluoroboric acid. [C 6 H 5 N 2]Cl + HBF 4 → [C 6 H 5 N 2]BF 4 + HCl. The tetrafluoroborate is more stable than the chloride. [2]
*** Benzene is a carcinogen (cancer-causing agent). *** Very flammable. The pure material, and any solutions containing it, constitute a fire risk. Safe handling: Benzene should NOT be used at all unless no safer alternatives are available. If benzene must be used in an experiment, it should be handled at all stages in a fume cupboard.
Chlorobenzene (abbreviated PhCl) is an aryl chloride and the simplest of the chlorobenzenes, consisting of a benzene ring substituted with one chlorine atom. Its chemical formula is C 6 H 5 Cl. This colorless, flammable liquid is a common solvent and a widely used intermediate in the manufacture of other chemicals.
The first step is the preparation of a benzene diazonium chloride solution, a diazonium salt created from the reaction of aniline with mixed nitric acid and hydrochloric acid. The second step involves adding the solution of the diazonium salt to 2-naphthol, to produce the diazo dye. Sudan I is prone to photodegradation when exposed to light.
Benzal chloride is an organic compound with the formula C 6 H 5 CHCl 2. [1] This colourless liquid is a lachrymator and is used as a building block in organic synthesis . Preparation and usage
Benzyl chloride, or α-chlorotoluene, is an organic compound with the formula C 6 H 5 CH 2 Cl. This colorless liquid is a reactive organochlorine compound that is a widely used chemical building block .
