CAS Number: 80-18-2. Anisole, or methoxybenzene, is an organic compound with the formula CH 3 OC 6 H 5. A phenyl group consists of a benzene ring with one of its hydrogens removed. One carbon gets a positive charge the other forms a C-E bond. identify the product formed from the side-chain oxidation of a given alkylbenzene. Since a mono-substituted benzene ring has two equivalent ortho-sites, two equivalent meta-sites and a unique para-site, three possible constitutional isomers may be formed in such a substitution. There is good evidence that the synthesis of phenol from chlorobenzene does not proceed by the addition-elimination mechanism (S N Ar) as previously described. Apart from that, the reaction is just the same - using the same nitrating mixture of concentrated In addition to the Thermodynamics Research Center (TRC) data available from this site, much more physical and chemical property data is available from the following TRC products: A Free Radical Substitution Reaction.

Often, more than one name is acceptable and it is not uncommon to find the old names … If there are two cycloalkanes in the molecule, use the cycloalkane with the higher number of carbons as the parent.5 ± 7. Protons on carbons directly bonded to an aromatic ring, called benzylic protons, show up about 2. That means that you would use a lower temperature to prevent more than one nitro group being substituted - in this case, 30°C rather than 50°C.
