The point group for Benzene is D6h.
The melting point of Benzene is 5.5 and its Boiling point is 80.1. So, Below 5.5 , Benzene is a solid. Between 5.5 and 80.1 Its a liquid. After 80.1 Benzene is a Gas..
Hi ,As you know from the structures of both the compounds that toluene has a methyl group on the benzene ring which is electron releasing group and hence activate the benzene ring by pushing the elctrons on the benzene ring. On the other hand nitro group on the benzene ring is electron withdrawing group which deactivates the benzene ring by withdrawing the electrons from the benzene ring . Now in the nitration attack of the nucleophile ( NO2 +) takes place. Hence reaction will takes place on that benzene faster which have more electron density on its ring which is the case of toluene.
Benzene has a lower boiling point than toluene because it has weaker intermoleclar forces. Benzene has a higher melting point than toluene because it is more symmetrical.
since benzene has a very less boiling point , it will evaporate easily if the mixture is heated . Thus we can obtain the vapour and condense it to obtain solid benzene
Yes (and no!) The styrene molecule is a benzene ring with a -CH=CH2 group attached. In the polymerisation process, the double bonds in two adjacent groups are broken and joined to form a chain: -CH-CH2-CH-CH2-CH-CH2-CH-CH2-....... with a benzene ring off each -CH- group. I believe the benzene group is referred to as a "phenyl group" in complex molecules, such as polymers like polystyrene.
because nitro group is ring deactivating group, nitration of nitro benzene is more difficult than benzene.
The IUPAC name for Benzene is Benzene. It forms the basis for other IUPAC-named benzene derivatives like 1,2-dimethylbenzene etc.Benzene as a substituent group is called the phenyl group. (e.g. phenylethylamine)IUPAC name of Benzene is 1,3,5-cyclohexatriene.

It contains a Secondary Amine group as well as a Secondary Hydroxyl group. There is also a benzene ring which is not considered a functional group.

Nitrobenzene has a nitro group.Benzene lacks that group
