Why does methylbenzene have higder boiling point than benzene?

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 partial pressures of water and benzene will be their corresponding vapor pressures at the boiling point so it must add up to 1 atm and this happens at roughly about 342-343 K.
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 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
How does the boiling point of saltwater compare to the boiling point of freshwater?
The boiling point of freshwater is lower than the boiling point of saltwater.

What is the boiling point of a 2.47 molal solution of napthalene in benzenethe boiling point of benzene is 80.1?
the boiling point of platnium is 2500c
Why is it that aniline has a high boiling point to phenol and phenol has a high boiling point than toluene and toluene has a high boiling point than benzene?
It s the structure and bonding of Aniline, Phenol, Benzene and Toluene that causes the differences in the 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 weaker intermoleclar forces. Benzene has a higher melting point than toluene because it is more symmetrical.
Which has a lower boiling point butane or water?
benzene has lower boiling point than water

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 is the boiling point of 2 pentanone?
The boiling point of benzene is 176 oF (80.1 oC).
What separation method do you use to separate benzene from a mixture of benzene and methyl benzene?
since benzene has a very less boiling point , it will evaporate easily if the mixture is heated . Thus we can obtain the vapour and condense it to obtain solid benzene
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.

5.2
What is the point group for Benzene?
The point group for Benzene is D6h.
