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
Yes, propane is actually a gas at room temperature, hexane is a liquid.
The reason for this is that hexane is a larger molecule than propane, so there are more intermolecular forces between molecules in hexane, giving it a higher boiling point.
Hexane has 6 carbon atoms while pentane has 5 carbon atoms. So the surface area of hexane is higher than pentane. Therefor the boiling point of hexane is high.
of course it's BUTANOL because of it's -OH bond, it is capable of Hydrogen bonding, which is very difficult to break during heating. :)
butane has the higher boiling point.
Hexane
octane has the highest boiling point than hexane
Octane has a higher boiling point than pentane because octane has a larger number of carbon atoms than propane
Think in terms of room temperature. Hexane is a liquid that is flammable, but is used in cleaning solvents and stuff like around the garage. Propane is the gas that comes in a steel bottle that you use for gas stoves and barbeque grills. So if you let propane out into the room its a gas and so it already past its boiling point. So the boiling point of Hexane is hotter than room temperature and the boiling point of propane is lower than room temperature. The actual numbers are 69 C and -42 C.
you can use the Clausius-Clapeyron equation if you know the temperature of hexane at 1.5 ATM
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.
Higher molecular weight, so needs more kinetic energy (higher temperature) to enter the gaseous phase.
somewhere around 56 degrees C
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.
The boiling point of hexane is 68 degrees Celsius, while the boiling point of butanol is 117.4 degrees Celsius. There is a difference of 49.4 degree Celsius between their boiling points.

Methanol
The boiling point of any compound is determined by how much energy it takes to break apart the intermolecular bonds. C6H14 has very low intramolecular forces compared to the polar bonds of another compound, such as water.
n-hexane is the unbranched alkane C6H14. All the bonds in the molecule are covalent. the bonds between the molecules are the weak London dispersive forces, n-hexane has a melting point of around -96 0C and a boiling point of around 68 0C.
Ethene, propene and butene. Ethene's boiling point is -104 Propene's " " " -48 But-1-ene " " " -6 Pentene being the alkene with the lowest number of carbons which is a liquid at room temperature (boiling point 30) So hot countries may count this as a gas!! Found on wiki, do some research and dont be lazy!!
The boiling point of benzene is about 80 0C while that of hexane is 69 0C, so Hexane is more volatile.
