Two Benzene Rings Name

Two ways of representing a phenyl group.

Two benzene rings name. Thienothiophene are the fusion of two thiophene rings. Phenylamine is a primary amine and contains the nh 2 group attached to a benzene ring. Phosphaphenalenes are a tricyclic phosphorus containing heterocyclic system derived from the carbocycle phenalene. For azepine benzazepine is the preferred name.

The old name for phenylamine is aniline and you could also reasonably call it. But let s say this carbon over here it has one two three bonds. If i didn t draw anything else you d just assume that there s also a hydrogen here. A phenyl group consists of a benzene ring with one of its hydrogens removed.

A compound containing a benzene ring which has one or more alkyl substituents is called an arene. Naphthalene is the most abundant single constituent of coal tar a. If you draw a benzene ring with one group attached you have drawn a phenyl group. You should already know the names and structures of several of the hydrocarbons shown in figure 15 1.

As it contains only carbon and hydrogen atoms benzene is classed as a hydrocarbon. Likewise the compounds with two benzene rings fused to the central heterocycle are carbazole acridine and dibenzoazepine. Naphthalene the simplest of the fused or condensed ring hydrocarbon compounds composed of two benzene rings sharing two adjacent carbon atoms. Remember that the phenyl group is a benzene ring minus a hydrogen atom c 6 h 5.

Benzene is a natural constituent of crude oil and is one of the elementary petrochemicals. So say i have this molecule right here. Chemical formula c 1 0 h 8 it is an important hydrocarbon raw material that gives rise to a host of substitution products used in the manufacture of dyestuffs and synthetic resins.
