Butane is a smaller molecule, so the London Dispersion forces between molecules of butane hold the molecule together better than the London Dispersion forces of a hexane molecule. In short, it requires more energy to separate butane molecules from each other than hexane molecules.

Octane has a higher boiling point than pentane because?
Octane has a higher boiling point than pentane because octane has a larger number of carbon atoms than propane
Why n-pentane has higher melting point than neopentane?
It is because n-pentane is a straight chain hydrocarbon meaning it has more surface area to reach the boiling point, neopentane has significantly less surface area that's why it will boil quicker than n-pentane. The more branched molecule, the lower is its boiling point will be & the less branched molecule, the higher its boiling point will be. For combustion energy the opposite holds true, the more branched molecule has a higher energy than an unbranched one.Hope You Like My Answer...By rananeeraj168@gmail.com in facebook
Which has the highest boiling point hexane or pentane?
Octane. The boiling point of straight-chain alkanes increases within its homologous series (meaning methane has a lower boiling point than ethane, which is lower than propane, etc). Hexane : Boiling Point 69 o C Octane : Boiling Point 125.5 o C
Does chlorine or oxygen has higher boiling point?
Chlorine has higher boiling point.
How does pressure affect boiling point?
The boiling point is that temperature when the SATURATEDvapor pressure of a liquidbecomes equal tothe surrounding pressure.Thus the higher the sorrounding pressure, the higher the boiling point.
Octane has a higher boiling point than pentane because?
Octane has a higher boiling point than pentane because octane has a larger number of carbon atoms than propane
Is pentane a liquid at 40 degrees?
Yes, unless you mean 40oC. That is because the boiling point of pentane is 36.1oC (97oF). So above the boiling point temperature pentane would exist as a gas.
Why n-pentane has higher melting point than neopentane?
It is because n-pentane is a straight chain hydrocarbon meaning it has more surface area to reach the boiling point, neopentane has significantly less surface area that's why it will boil quicker than n-pentane.

Isobutane melting point and boiling point?
Butanone boils (at StP) at 79.64 °C and melts at -86 °CBy the way: the naming of butanone (CH3COCH2CH3) is not 2-butanone, because 3-butanone is the same compound and 1-butanone does not exist: this is butanal.
Why does heptane have a higher boiling point than pentane?
The carbon skeleton of pentane contains 5 carbon atoms, the carbon skeleton of heptane contains 7 carbon atoms. The main reason for increased boiling point are London dispersion forces, these increase the with the number of electrons- so as heptane has more electrons its dispersion forces are greater and the boiling point is higher. Another contributory factor is the mass as the molecule of heptane is heavier and this means it takes more energy to get it to vaporise.
Which has the highest boiling point out of pentane neopentane and isopentane?
somewhere around 56 degrees C
Does chlorine or oxygen has higher boiling point?
Chlorine has higher boiling point.
How does pressure affect boiling point?
The boiling point is that temperature when the SATURATEDvapor pressure of a liquidbecomes equal tothe surrounding pressure.Thus the higher the sorrounding pressure, the higher the boiling point.
How does salt effect boiling point?
The boiling point is higher.
Which substance has higher boiling point nitrogen fluoride or NH3?
Boiling point of NH3: -33,34 0C Boiling point of NF3: -129,1 0C The boiling point of ammonia is higher.
What happens if boiling point is higher than melting point?
The boiling point is always higher than the melting point.
