What else can I help you with?
Is a mixture of water and benzene homogeneous or heterogeneous?
Neither or both; Benzene C6H6 is a pure compound, not a mixture, thus the liquid and gas state are homogenous. Solid state could be multi-crystalline, but not sure about that (at least depending on low temperature)
What happens when bromine is mixed with benzene with an FeBr3 catalyst?
When bromine is mixed with benzene in the presence of FeBr3 catalyst, bromination of benzene occurs. The FeBr3 catalyst activates the bromine molecule to form a bromine cation, which then electrophilically attacks the benzene ring, replacing a hydrogen atom with a bromine atom. This results in the formation of bromobenzene.
Why is benzene- water unsuitable as a mixed solvent?
Benzene is not miscible in water, leading to poor solvent interaction between the two compounds. This results in incomplete dissolution of solutes in the mixture. Additionally, benzene is considered toxic, making it undesirable for use in solvent mixtures.
How can one test for benzene in water?
One can test for benzene in water using methods such as gas chromatography or mass spectrometry, which can detect even trace amounts of benzene in the water sample. These methods involve extracting the benzene from the water and analyzing it to determine its concentration.
Why benzene ring insoluble in water?
The benzene ring is nonpolar due to its symmetrical arrangement of carbon and hydrogen atoms, which makes it unable to form hydrogen bonds with water molecules that are necessary for solubility in water. This lack of interaction between benzene and water results in low solubility of benzene in water.

Will benzene float on water?
Yes, benzene floats on water. Benzene has a density of 0.88, water has a density of 1.0. The solubility in water is just 0.8 g/l at 25°C (Wikipedia)
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.
Where the water is set in water benzene mixture?
Bottom. Water density is 1kg/m^3 benzene density is 876.50kg/m^3 so water is basically "heavier" than benzene.

Benzene is a non-polar molecule and meaning that it does not have a positive or negative side Which statement BEST describes how benzene will dissolve in water?
Benzene is non-polar as it does not have the electronegative atoms such as oxygen or chlorine in it. Therefore, benzene does not exhibit polarity as opposed to molecules which include as water.

The benzene ring is nonpolar due to its symmetrical arrangement of carbon and hydrogen atoms, which makes it unable to form hydrogen bonds with water molecules that are necessary for solubility in water. This lack of interaction between benzene and water results in low solubility of benzene in water.
When benzene reacts with bromine water will it decolourise bromine water or not?
No!! Benzene wont de colourise bromine water although it is an unsaturated compound ,as it is an aromatic compound and it does not undergo addition reaction.
Does Benzene and water form a good solution?
No benzene is extremely hydrophobic and sits like an oil on top of the water.
How could you separate a mixture of H₂O and benzene?
One way to separate a mixture of water and benzene is through a process called distillation. Since benzene has a lower boiling point than water, the mixture can be heated to a temperature at which benzene evaporates but water remains a liquid. The vaporized benzene can then be collected and condensed back into a liquid form, effectively separating the two components.
