C8H18 bcz volatility depends upon intermolecular forces and alkanes have van der wall f.o.a and this force depends upon molar mass..Since c8h18 has lower molar mass so the force is less and intermolecular attraction is less.. So it can easily get vaporized . Therefore c8h18 is more volatile..

What is the difference between octane and dodecane?
Octane is an eight-carbon hydrocarbon compound commonly found in gasoline, while dodecane is a twelve-carbon hydrocarbon that is typically used as a standard reference in chromatography. Octane is lighter and more volatile compared to dodecane, which has a higher molecular weight and boiling point.
What is the structural isomer of C8H18 with the lowest boiling point?
In organic chemistry, alkanes such as C8H18 have structural isomers. The more these isomers are branched the lower the boiling point is. The reason for this, is that un-branched alkanes have a higher mass area, they are more likely to have more potential points of attachments for other atoms or molecules which would then raise intramolecular forces thus increasing boiling points. The structural isomer of C8H18 that has the boiling point is systematically known as 2,2,3,3-tetramethylbutane.
How is a substituted hydrocarbon created from a hydrocarbon chain?
A substituted hydrocarbon is created from a hydrocarbon chain by replacing one or more hydrogen atoms with a different functional group, such as an alcohol, halogen, or nitro group. This substitution reaction can be achieved through various chemical reactions, such as halogenation, hydroxylation, or nitration, depending on the desired functional group to be added to the hydrocarbon chain.
Why a toxic volatile liquid more dangerous than a toxic non volatile liquid?
A toxic volatile liquid can easily vaporize into the air, increasing the risk of inhalation and exposure to larger areas. This can lead to quicker absorption into the body and potentially result in more severe health effects compared to a non-volatile liquid that remains more localized and less likely to become airborne.
How does the volatility of a hydrocarbon change as its carbon chain length increases?
As the carbon chain length of a hydrocarbon increases, its volatility generally decreases. This is because longer carbon chains have stronger intermolecular forces, such as van der Waals forces, which make it harder for the molecules to escape into the gas phase. Shorter chain hydrocarbons are typically more volatile and have lower boiling points compared to longer chain hydrocarbons.
What is the difference between octane and dodecane?
Octane is an eight-carbon hydrocarbon compound commonly found in gasoline, while dodecane is a twelve-carbon hydrocarbon that is typically used as a standard reference in chromatography. Octane is lighter and more volatile compared to dodecane, which has a higher molecular weight and boiling point.
Is ethylamine more volatile than methylamine?
Ethylamine is more volatile than methylamine.

How do you determine less volatile and more volatile?
The higher the boiling point, the less volatile. And vice versa.
Is ethanol more volatile than acetone?
Acetone is more volatile than ethanol.
Why do they call a carburetor a carburetor?
The word carburetor comes from the French carburemeaning "carbide".[1] Carburer means to combine with carbon. In fuel chemistry, the term has the more specific meaning of increasing the carbon (and therefore energy) content of a fuel by mixing it with a volatile hydrocarbon.
Is a short-chain hydrocarbon more viscous than a long chain hydrocarbon?
Typically the shorter the carbon chain, the LESS viscous the hydrocarbon. The longer the chain, the MORE viscous the hydrocarbon. For example consider the viscosity and molecular size in: Gasoline < Diesel < Motor Oil < Tar Viscosity increases with the molecular size and length of hydrocarbon chain.
Is CBr4 more volatile than CCl4?
ch4 is the most volatile
Why are cracking large hydrocarbon molecules more useful than the original large molecules?
Cracking large hydrocarbon molecules produces smaller molecules that are lighter and have higher demand in the market, such as gasoline, diesel, and jet fuel. These smaller molecules are more volatile and easier to transport and utilize in various industries like transportation and manufacturing. It also helps to maximize the yield of valuable products from crude oil.
Who require more temperature for easily evaporation its volatile liquid or non volatile liquid?
Volatile liquids require less temperature for easy evaporation compared to non-volatile liquids. This is because volatile liquids have lower boiling points and higher vapor pressure, making them more likely to evaporate even at lower temperatures.
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.
Why is hydrocarbon important?
it makes smaller molecules which is more useful.
