Two Benzene Rings Name

Two ways of representing a phenyl group.

Two benzene rings name.

Benzene is an organic chemical compound with the molecular formula c 6 h 6 the benzene molecule is composed of six carbon atoms joined in a planar ring with one hydrogen atom attached to each. Benzene is a natural constituent of crude oil and is one of the elementary petrochemicals. But let s say this carbon over here it has one two three bonds. Likewise the compounds with two benzene rings fused to the central heterocycle are carbazole acridine and dibenzoazepine.

Naphthalene is the most abundant single constituent of coal tar a. As it contains only carbon and hydrogen atoms benzene is classed as a hydrocarbon. A compound containing a benzene ring which has one or more alkyl substituents is called an arene. If you draw a benzene ring with one group attached you have drawn a phenyl group.

A phenyl group consists of a benzene ring with one of its hydrogens removed. Remember that the phenyl group is a benzene ring minus a hydrogen atom c 6 h 5. Now if i were to add something to the benzene ring it s pretty straightforward to name it. If i didn t draw anything else you d just assume that there s also a hydrogen here.

Phosphaphenalenes are a tricyclic phosphorus containing heterocyclic system derived from the carbocycle phenalene. So say i have this molecule right here. So let s see i have that. You should already know the names and structures of several of the hydrocarbons shown in figure 15 1.

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. Naphthalene the simplest of the fused or condensed ring hydrocarbon compounds composed of two benzene rings sharing two adjacent carbon atoms. Phenylamine is a primary amine and contains the nh 2 group attached to a benzene ring.
