you can try distillation. benzene has a boiling point of 80 deg C and DMF is more like 150 deg C. i don't think it will form an azeotrope (may be wrong though).
if it does form an azeotrope and the concentration of DMF is not too high, you can try washing the distillate in a sep funnel with water. DMF is freely miscible in water, whereas benzene is non-soluble in water.
Benzene is a specific chemical compound with the formula C6H6, while petroleum benzene refers to benzene that is derived from crude oil during the refining process. Petroleum benzene may contain impurities and other hydrocarbons not present in pure benzene.
yes benzene is pure substance with chemical formulaC6H6
The molar mass of benzene is 76,11 g.
Neither. Benzene is a compound. It is considered to be an aromatic compound.
Actually "Borazine" (or sometimes called Bolazole) is often called as inorganic benzene, as it has a hexagonal structure similar to that of benzene. Also it is iso-electronic with benzene. It has the formula, B3N3H6.
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.
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.
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.
toluene is the name for methyl benzene. You have a benzene ring of C6H6 . One of the hydrogens (H) is substituted for a methyl functional group Hence its structure is C6H5-CH3
Benzene is sparingly soluble in water due to the hydrophobic nature of its aromatic structure. It will form separate layers in the mixture, with benzene floating on top of the water. Benzene is considered immiscible with water.
The product is an aldehyde.

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.
Benzene (both liquid and gas and solid) only consists of molecules with formula C6H6 (in a 6-cornered ring formed by the 6 C atoms, each of which also holds one H atom. This doesn't change by physical processes like boiling or freezing because it is NO chemical reaction.
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.
Fractional distillation in a distillation column will remove benzene from hexane. The vapor-liquid-equilibrium data indicate that depending on initial and desired concentrations, multiple theoretical stages will likely be needed. See also vapor liquid equilibrium chart for benzene and hexane.
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)
