184.5 °c (364.1 °f; 457.7 k) Benzyl bromide is an isomer, which has a bromine substituted for one of the hydrogens of toluene 's methyl group, and it is sometimes named α-bromotoluene. Preparation
3-Methylcatechol (3-methylbenzene-1,2-diol) 4-Methylcatechol (4-methylbenzene-1,2-diol) Orcinol (5-methylbenzene-1,3-diol) Methoxyphenols — can be derived from benzenediols by O-methylation. Guaiacol (2-methoxyphenol, O-Methylcatechol) Mequinol (4-Methoxyphenol) Dimethoxybenzenes — can be derived from benzenediols by two rounds of O ...
This group typically excludes compounds in which either benzene is fused to another ring (bicyclic, tricyclic, polycyclic) [1] or includes a heteroatom, or where the methane connects to three or four benzenes. Ball-and-stick model of the benzhydryl radical. The benzhydryl radical can be abbreviated Ph 2 CH• or Bzh. [2]
For example, (C 6 H 5)(CH 3) 2 C + is referred to as a "benzylic" carbocation. The benzyl free radical has the formula C 6 H 5 CH 2 •. The benzyl cation or phenylcarbenium ion is the carbocation with formula C 6 H 5 CH + 2; the benzyl anion or phenylmethanide ion is the carbanion with the formula C 6 H 5 CH − 2.
A laboratory route to 2- and 4-chlorotoluene proceeds from 2- and 4-toluidines (i.e. 2- and 4-aminotoluene). These compounds are diazotized followed by treatment with cuprous chloride. [1] Industrially, the diazonium method is reserved for 3-chlorotoluene. The industrial route to 2- and 4-chlorotoluene entails direct reaction of toluene with ...
The simplest member, toluene (or methylbenzene), has the hydrogen atom of the benzene ring replaced by a methyl group. The chemical formula of alkylbenzenes is C n H 2n-6. [2] Safety hazards of toluene. Oftentimes, toluene is used as an organic solvent.
Bromobenzene is prepared by the action of bromine on benzene in the presence of Lewis acid catalysts such as aluminium chloride or ferric bromide. [3]Bromobenzene is used to introduce a phenyl group into other compounds.
The acidity of the methylene group in diphenylmethane is due to the weakness of the (C 6 H 5) 2 CH–H bond, which has a bond dissociation energy of 82 kcal mol −1 (340 kJ mol −1). [5] This is well below the published bond dissociation energies for comparable C–H bonds in propane , where BDE((CH 3 ) 2 CH–H)=98.6 kcal mol −1 , and ...
