How does the resonance structure of nitrobenzene contribute to its chemical properties and reactivity?
The resonance structure of nitrobenzene helps stabilize the molecule, making it less reactive than benzene. This stability affects its chemical properties by reducing its tendency to undergo certain reactions, such as electrophilic aromatic substitution.
Why is that the temperature of mono nitration of benzene be maintained at 50 degree Celsius?
So that only one NO2+ is substituted for the hydrogen on one of the carbons in benzene , if it was above 50 degree Celsius then more than one hydrogen would be substituted and mono nitration is only one substitution of hydrogen for NO2+
What are the key differences between phenol and benzene in terms of their chemical properties and reactivity?
Phenol and benzene are both aromatic compounds, but phenol has a hydroxyl group (-OH) attached to the benzene ring, making it more reactive than benzene. Phenol can undergo reactions such as oxidation and substitution more readily than benzene. Additionally, phenol is more acidic than benzene due to the presence of the hydroxyl group.
How do you separate kerosene from benzene?
Kerosene and benzene can be separated by fractional distillation. Since benzene has a lower boiling point than kerosene, the mixture can be heated to vaporize the benzene, which is then collected as a separate fraction.
In benzene and chlorobenzene which one is more polar?
Chlorobenzene is more polar than benzene because it has a chlorine atom attached to the benzene ring, which induces a dipole moment and increases its overall polarity compared to benzene.
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.

Is phenol easier or more difficult to substitute with bromine than benzene?
The substitution reactions of phenol are easier than benzene, phenol directly reacts with bromine and gives tribromo phenol while benzene requires FeCl3 as a catalyst and gives mono bromo phenol.
What is the vapor pressure of nitrobenzene at Boiling point and at 102 degree Celsius?
The vapor pressure of nitrobenzene at its boiling point (210.9°C) is equal to the atmospheric pressure, which is 1 atm. At 102°C, the vapor pressure of nitrobenzene would be lower than 1 atm, as the boiling point is higher than 102°C.
Which is nitrated faster toluene or phenol Explain?
Phenol is nitrated faster than toluene because phenol is more reactive towards electrophilic aromatic substitution reactions due to the presence of the hydroxyl group (-OH) which activates the benzene ring by donating electrons to it. This increases the electron density on the ring and makes it more susceptible to electrophilic attack by the nitronium ion in nitration reactions.
Why is aspirin more reactive than benzene?
Benzene has a stable structure. Aspirin has an carboxylic group with delocalized electrons. So aspirin is more reactive than benzene.

Which is the upper layer between water and benzene?
Benzene is less dense than water, so it will float on top of water, making it the upper layer in this case.
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.
