It is a bigger molecule and so the van der Waals dispersion forces will be bigger.
Methylbenzene also has a small permanent dipole, so there will be dipole-dipole attractions as well as dispersion forces. The dipole is due to the CH3 group's tendency to "push" electrons away from itself. This also affects the reactivity of methylbenzene

Why does methylbenzene have higher boiling point than benzene?
Benzene is a tidy, symmetrical molecule and packs very efficiently. The methyl group sticking out in methylbenzene tends to disrupt the closeness of the packing. If the molecules aren't as closely packed, the intermolecular forces don't work as well and so the melting point falls.
Asume benzene insoluble in water the normal boiling point of benzene and water is 80.1'c and 100'c respectively at a pressure of 1 ATM what will be the boiling point of mixture of benzene and water?
The boiling point of a mixture of benzene and water will be higher than the boiling point of either component alone, due to the presence of both compounds. The exact boiling point would depend on the concentrations of benzene and water in the mixture according to Raoult's law. If benzene and water form an ideal solution, the boiling point of the mixture would lie between 80.1°C and 100°C.
What is more volatile benzene or hexane?
The boiling point of benzene is about 80 0C while that of hexane is 69 0C, so Hexane is more volatile.
What and Why is more volatile benzene or acetone?
Benzene is generally more volatile than acetone due to its lower boiling point and higher vapor pressure at room temperature. Benzene has a boiling point of about 80.1°C, while acetone's is around 56.5°C; however, the volatility is also influenced by molecular structure and intermolecular forces. Benzene's non-polar structure leads to weaker van der Waals forces compared to the polar nature of acetone, resulting in higher volatility for benzene. Therefore, benzene evaporates more readily under similar conditions.
What happens to the boiling point of benzene when a solute is added?
if you put an ionic compound in a polar substance it will raise the boiling point because the resulting ion dipole bonds will be stronger than the previously existing dipole dipole bonds
Why does methylbenzene have higher boiling point than benzene?

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.

What is the boiling point of a 2.47 molal solution of napthalene in benzenethe boiling point of benzene is 80.1?
To determine the boiling-point elevation of the solution, we need to use the formula: ΔTb = iKbm, where ΔTb is the boiling point elevation, i is the van't Hoff factor (for napthalene, i = 1 because it doesn't dissociate), Kb is the ebullioscopic constant of the solvent (benzene), and m is the molality of the solution (2.47 mol/kg). Plug in the values and solve for ΔTb. Add this value to the boiling point of benzene (80.1°C) to find the boiling point of the solution.
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.
What is the boiling point of benzine?
Boiling Point (760 mm Hg); 80.1 deg. C (176 deg. F)
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..
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.
Is benzene or ethyl ether highly volatile?
Ethyl ether is more volatile than benzene. Ethyl ether has a lower boiling point and vapor pressure, making it easier for it to evaporate rapidly. Benzene is less volatile compared to ethyl ether due to its higher boiling point and lower vapor pressure.
What is more volatile benzene or hexane?
The boiling point of benzene is about 80 0C while that of hexane is 69 0C, so Hexane is more volatile.
What is the boiling point of 2 pentanone?
The boiling point of benzene is 176 oF (80.1 oC).
What state is benzene in at room temp?
Benzene is a liquid at room temperature. The boiling point of benzene is 80.1 degrees Celsius, which means it is typically found in a liquid state at temperatures below that.
