Why does isomerisation turn straight chain alkanes into alkanes with lower boiling temperature?
Wiki User
∙ 11y ago
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.

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.
Which of these alkanes methane ethane propane and butane expect to have the highest boiling point?
Butane because it contains more atoms and is heavier.
Which has the higher temperature - boiling water or ice?
boiling water
Why alcohol have higher boiling point than alkanes?
this is because of the presence of intermolecular hydrogen bonding in the polar molecules. energy is needed to over come the attractive forces resulting in higher boiling point values.
How can the temperature in the autoclave go above boiling temperature of 212 F?
At higher pressure the boiling point is higher.
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 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!!
What is the temperature of boiling water at sea level?
The temperature of boiling water at sea level is 100 The temperature of boiling water at sea level is 211.149°F.
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.)
Which of these alkanes methane ethane propane and butane expect to have the highest boiling point?
Butane because it contains more atoms and is heavier.
Which has the higher temperature - boiling water or ice?
