Explain why benzene C6H6 has a lower boiling point than water?
Appearinvisible
Benzene, C6H6 is a non-polar simple covalent molecule with instantaneous induced dipole-Induced dipole interactions (Dispersion forces, Van der waal's forces of attraction). Water on the other hand is a polar simple covalent molecule with hydrogen bonding.
Water has hydrogen bonding because it's hydrogen atoms are attached to a highly electronegative atom (Oxygen) which pulls the bonding electrons so close to itself that the valence shell of the hydrogen atoms appear to be empty and ready to accept a lone pair of electrons from an oxygen atom of another water molecule. (In this case oxygen atoms have 2 lone pairs to contribute to hydrogen bonding.
Hydrogen bonding is far more stronger than dispersion forces and thus requires more energy to break. As such, water has a higher boiling point (100 0C) than benzene (80.1 0C) because more energy is required to break the forces of attraction holding the molecules of water together.

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.
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
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 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
How does abnormally low pressure affect the boiling point of a compound?
lower pressure means a lower boiling point.
Which has a lower boiling point butane or water?
benzene has lower boiling point than water

Explain why a solution has a lower boiling point than the pure solvent?
Most solutions have a HIGHER boiling point than the pure solvent. A solution with a lower boiling point than the solvent has formed an azeotrope.
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.
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.

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 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.
Does ethanol has the lower boiling point?
It depends what chemical or compound you are comparing the boiling point to. Ethanol has an atmospheric pressure boiling point of 78.1 °C (172.6 °F). This is slightly lower than the boiling point of water at the same pressure, much lower than the boiling point of iron, much higher than the boiling point of bromine.
