What is the state of benzene at 15 degree Celsius?
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..
What separation method do you use to separate benzene from a mixture of benzene and methyl benzene?
Fractional distillation is commonly used to separate benzene from a mixture of benzene and methyl benzene. Benzene has a lower boiling point compared to methyl benzene, allowing it to be separated by distillation based on the difference in their boiling points.
Why does benzene have a lower boiling point but a much higher melting point than toluene?
Benzene has a lower boiling point than toluene because it has a symmetric structure that experiences weaker van der Waals forces, making it easier for benzene molecules to separate and vaporize. The higher melting point of benzene compared to toluene is due to the presence of delocalized electron cloud in benzene, which results in stronger intermolecular interactions (π-π interactions) between benzene molecules in the solid state.
Why nitration of toluene is easier than benzene?
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.
Does Polystyrene contain benzene rings?
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.
What is the name of benzene with an NH2 group?
Aniline is the name of benzene with an NH2 group attached.
What is the name of the functional group found in benzene?
The functional group found in benzene is called an aromatic ring.
What is the triple point for benzene?
The triple point for benzene is the temperature and pressure at which benzene can exist simultaneously as a solid, liquid, and gas. For benzene, the triple point occurs at a temperature of 5.5 degrees Celsius and a pressure of 48.6 kilopascals.
What is the IUPAC name of 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.

What is the chemical formula for keryl benzene?
The chemical formula for keryl benzene is C6H5CH3. It is a type of alkylated benzene where a methyl group is attached to the benzene ring.
What is the group difference between toluene and benzene?
Benzene - a six carbon, six hydrogen [planar] ring - C6H6 - has no side-groups. Yet when any one single side-hydrogen is replaced with one Methyl (-CH3) Group, we have Toluene. Short Answer = one methyl group.

What is the flash point of benzene?
The flash point of benzene is -11°C (12°F). It is the temperature at which benzene gives off enough vapor to ignite in the presence of an ignition source.
