Why does isomerisation turn straight chain alkanes into alkanes with lower boiling temperature?
Isomerisation causes straight chain alkanes to become branched alkanes which prevents the chains from moving to close proximities of each other. This reduces the van der Waal's intermolecular forces between chains so less energy is needed to overcome the forces and thus a lower boiling point.

Which alkane has the lowest boiling point among all alkanes?
The alkane with the lowest boiling point among all alkanes is methane.
Why alcohol have higher boiling point than alkanes?
Alcohols have higher boiling points than alkanes because alcohols can engage in hydrogen bonding between the hydroxyl (-OH) groups, which increases the intermolecular forces between molecules. This stronger intermolecular attraction requires more energy to break the bonds and thus results in a higher boiling point for alcohols compared to alkanes, which only have weaker London dispersion forces.
What is it called the temperature at which a liquid boils?
The temperature at which a liquid boils is called its boiling point.
Which has higher boiling point aldehyde or ketone?
the alkanes are saturated and contains more atoms so therefore contain more electrons this results in stronger dispersion forces the alkenes and unsaturated contain less atoms less electrons weaker dispersion force compared to the alkane
How can you use boiling points and melting points to determine a solid liquid or gas that an element would be in at a certain temperature?
If the temperature is below the melting point then the element is a solid.If the temperature is above the melting point but below the boiling point, then the element is a liquid.If the temperature is above the boiling point, then the element is a gas.
How do oil companies use cracking isomerisation and reforming to process fractions from crude oil?
Cracking, isomerisation and reforming are usually used to make smaller branched alkanes from the long-chained alkanes. Small branched alkanes can not pack as closely together, so they have weak Van der Waals forces. It means that the products will have low boiling points and are better fuels as they burn more easily.
Which alkane has the lowest boiling point among all alkanes?
The alkane with the lowest boiling point among all alkanes is methane.
Which of the alkanes are liquids at room temperature?
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!!
Which lists straight-chain alkanes from lowest to highest boiling point?
Straight-chain alkanes can be listed from lowest to highest boiling point as follows: methane (C1), ethane (C2), propane (C3), butane (C4), pentane (C5), hexane (C6), heptane (C7), octane (C8), nonane (C9), and decane (C10). As the number of carbon atoms increases, the boiling point tends to rise due to greater molecular weight and increased van der Waals forces.
How can alkanes be described?
Alkanes are hydrocarbons with only single bonds between carbon atoms, making them saturated hydrocarbons. They are colorless, odorless, and nonpolar molecules that are relatively unreactive under normal conditions. The physical properties of alkanes, such as boiling point and solubility, increase with increasing molecular weight.
What is the volatility of Alkanes?
Alkanes high volatility as the type of Intermolecular Force of it is Van Der Waals', which is the weakest bond.
How does a substance's boiling point determine its state at room temperature?
A substance's boiling point indicates the temperature at which it transitions from a liquid to a gas. If the substance's boiling point is below room temperature, it will be a gas at room temperature. If the boiling point is above room temperature, it will be a liquid at room temperature.
Why alcohol have higher boiling point than alkanes?

What is it called the temperature at which a liquid boils?
The temperature at which a liquid boils is called its boiling point.
Can boiling temperature of an element change?
The boiling temperature of an element can change by changing the pressure.
How long to poach pork?
If the water is boiling before you add the egg and the egg is at room temperature, (i.e. not straight out of the fridge) then around 2.5 minutes.3 minutes in softly boiling water.
At what temperature does a liquid become a gas?
At it boiling point: boiling temperature AND pressure:Water boiling at 100oC at 100 kPa (1 atm.)
