Hexane and pentane can be separated using fractional distillation because they have different boiling points. Hexane has a higher boiling point (68.7°C) than pentane (36.1°C), so by heating the mixture, the pentane will vaporize first and can be collected and condensed separately from the hexane.
What else can I help you with?
Why pentane and hexane will dissolve in each other in all proportions?
Pentane and hexane are both nonpolar molecules with similar molecular structures, so they have similar intermolecular forces (London dispersion forces). This allows them to mix together in all proportions because the attractive forces between molecules of the same kind (hexane-hexane, pentane-pentane) and between different kinds (hexane-pentane) are relatively similar in strength.
Why will pentane and hexane dissolve in each other?
Pentane and hexane are both nonpolar molecules with similar intermolecular forces (London dispersion forces). As a result, they have a similar polarity and can easily mix and dissolve in each other.
Why is the bioling point of hexane greater than that of pentane?
The boiling point of hexane is higher than that of pentane because hexane has a larger molecular mass and stronger London dispersion forces between its molecules. These stronger intermolecular forces require more energy to overcome, resulting in a higher boiling point for hexane compared to pentane.
What is the volume percent concentration of hexane in a solution made by mixing 50.0 mL of hexane with 1.0 L of pentane?
To calculate the volume percent concentration of hexane in the solution, you need to determine the total volume of the solution first. Mixing 50.0 mL of hexane with 1.0 L of pentane gives a total volume of 1.05 L (1000 mL + 50 mL). The volume percent concentration of hexane can be calculated as (volume of hexane / total volume) x 100. This gives (50 mL / 1050 mL) x 100 = 4.76% volume percent of hexane in the solution.
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

What are non examples of polarity?
pentane, hexane, benzene, toluene, and octane

These stronger intermolecular forces require more energy to overcome, resulting in a higher boiling point for hexane compared to pentane.
Does hexane or pentane have a stronger intermolecular force of attraction and why?
Hexane has stronger intermolecular forces of attraction compared to pentane due to its larger molecular size and greater surface area, which enhances van der Waals forces (London dispersion forces). The increased number of electrons in hexane leads to stronger temporary dipoles, resulting in greater attraction between molecules. Consequently, hexane exhibits higher boiling and melting points than pentane.

What are some examples of things that aren't solvents?
pentane, hexane, benzene, toluene, and octane
Which mixture would be easier to separate by distillation a mixture of pentane and octane or a mixture of pentane and a branched-chain octane isomer Explain your reasoning?
The mixture of pentane and octane would be easier to separate by distillation because these two compounds have a larger difference in boiling points compared to pentane and a branched-chain octane isomer. The branched-chain octane isomer would likely have a boiling point closer to that of pentane, making it more challenging to separate by distillation due to their closer boiling points.
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
Is naphthalene soluble in pentane?
Yes, naphthalene is slightly soluble in pentane due to their similar nonpolar characteristics. However, naphthalene is more soluble in nonpolar solvents like hexane or benzene.
What represents c6h14?
A saturated hydrocarbon (alkane). This can mean hexane, methyl pentane, ethyl butane, dimethyl butane etc.
What rhymes with methane?
death main.In chemestry ther are so many. Some are ethane,propane,heptane,octane,hexane,pentane
