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.

Why the melting point of arsenic is higher than boiling point?
The melting point is higher than the boiling point of Arsenic only because the melting point is when Arsenic is under pressure because otherwise it would sublimate, or turn directly from a solid to a gas, a the "boiling" point of 614 degrees Celsius and normal atmospheric pressures.
Will LiCl have a higher boiling point than water?
boiling point:1382 C Melting point: 605 C
Does CaO or CS2 have a higher melting point?
CaO has a higher melting point.
Does chlorine have a higher boiling point than iodine?
iodine is having higher boiling point
Why does chlorine have a higher boiling point than krypton?
To determine why chlorine's melting point (-100.98) is higher than krypton's melting point (-157.2), you must look at the electron configuration of the elements. 36Kr: [Ar]4s23d104p6, and 17Cl: [Ne]3s23p5. There is a trend in the periodic table that states that elements with paired electrons in the electron orbitals will have extremely low melting points (why all noble-gases have low melting points). So since krypton is a noble-gas, it has every electron orbital filled, forming an octet, therefore having a lower melting point. Chlorine, has a 3p5 orbital and therefore not completing the octet, or paired p-orbital, therefore having a higher melting point.
How melting and boiling points are affected by intermolecular forces?
The stronger the intermolecular forces, the higher the melting point and boiling point. The weaker the intermolecular forces, the lower the melting and boiling points are.
What happens if boiling point is higher than melting point?
The boiling point is always higher than the melting point.
How does IMF affect the boiling point or melting point of a substance?
The stronger the IMF, the higher the boiling point and the lower the melting point. The weaker the IMF, the lower the boiling point and the higher the melting point.
Why fast rate of heating gives higher melting and boiling point than the true one?
Because the temperature is higher hence make the boiling and melting point higher.
Why is glycerol's boiling point higher than toluene?
it just is you knowit goes higher with all the gas and you know what happens nextdon't you?
Do nonmetals have higher melting points or lower boiling points?
lower melting points
Do stronger intermolecular forces result in higher or lower boiling points?
An intermolecular force has both a boiling point and melting point
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.
Why is diamond a unusual non metal?
non-metals have lower density, melting and boiling point but diamond has higher density, melting and boiling point.
Weak dipole-dipole forces result in a what melting point?
The stronger the bonds between molecules; the higher the melting/boiling points. This makes sense if you think about it, melting/boiling is splitting up the molecules - the stronger they are bonded the more energy you will need
Does iodine have a higher melting and boiling point than florine?
Yes.
Is boiling point higher than melting point?
they are the same... dont know who wrote this but it can be the same such as dry ice, or different such as water. however boiling point will sometimes be higher than melting point
