What is the increment of change in a series of straight chain alkanes?
CH2
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.
How does the boiling point of a hydrocarbon change as its carbon chain length increases?
Generally speaking, boiling points increase as carbon chain length increases. This is because there are more atoms present in the hydrocarbon molecule and therefore more intermolecular forces (eg Van der Waals') that must be overcome. In addition the now heavier molecule requires greater energy (heat) to make the phase change to a gas. However, branching decreases boiling point; branched hydrocarbons cannot pack together as closely as unbranched ones, and so intermolecular forces are less strong. So, for example, the bp is higher for butane than 2-methylpropane (even though they contain the same number of C and H atoms).
What makes fats oils and waxes?
Fats and oils contain long chain esters of glycerol. Very large ones can be waxes, but many other compounds make waxes, including long chain alkanes.
What are alkane liquids that are continuous chains?
At normal pressure, the alkanes pentane (C5H12) through decane (C10H22) are liquids. Alkanes are organic compounds consisting of a single carbon chain of single covalently bonded carbon atoms surrounded by hydrogen atoms.
Why does viscosity go on increasing with increasing chain length of straight-chain alkanes but for isomeric alkanes viscosity increase with branching?
Viscosity increases with increasing chain length of straight-chain alkanes while that for isomeric alkanes increase with branching because of the difference in the number of rings contained within their hydrocarbons.
Why do alkanes get thicker and less runny as the length of the carbon chain increases?
The longer the carbon chain, it spreads out the atoms more equally which causes the carbon to get thicker and less runny.
What are short chain alkanes?
Cx = the number of carbon atoms in the molecule. Methane would be C1.According to the EPA (http://www.epa.gov/sites/production/files/documents/1999polychloroalkanes.pdf), "The normal paraffin fractions that are most commonly used in the manufacture of polychlorinated alkanes are short chain (C10 to C13, average C12), intermediate chain (C14 to C19, average C15), and long chain (C20 to C30, average C24) fractions." I've also seen people state any alkane between C2 and C4 - all the alkanes whose names don't contain the number of carbon atoms in their longest chain, written in Greek - is a short chain alkane, and another of our esteemed members defines them as alkanes from C2 to C6. IOW, what a short chain alkane is depends on the branch of chemistry you practice; a chemist in a polymer lab has a different view of the world than one in a fuels lab.Methane is not a short chain alkane because it isn't a chained alkane; chains have multiple links, which in alkanes are carbon molecules.
Is wax heterogenous or homogenous mixture?
Wax is a generally considered as a homogenous mixture of several different longer-chain alkanes, esters and other compounds.
Which compounds have the maximum possible number of hydrogen atoms on their carbon chain?
The alkanes have this feature.The entire group of alkanes has this characteristic.alkane
What is the increment of change in a series of straight chain alkanes?
CH2
What is the process that converts large alkanes to small alkanes and alkenes is called?
Long-chain alkanes can be broken into smaller hydrocarbons in a process called cracking, which may be thermal or catalytic.
Why do the alkanes get thicker and less runny as the length of the carbon chain increase?
This is because the longer the carbon chain, it spreads it out more equally which causes the carbon to get a lot more thicker and less runny Answered by a natural scientist who tries the experiments
What is the physical state of the smallest alkanes at room temperature?
Alkanes with a carbon chain of 5 up to 17 are liquids. So the set of liquid alkanes begins with pentane, C5H12.
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 quantity represents the prefix used in naming straight-chain alkanes with the exception of methane propane and butane?
The prefix used in naming straight-chain alkanes, excluding methane, propane, and butane, represents the number of carbon atoms in the chain. This prefix is derived from Greek or Latin numerical prefixes, such as "pent-" for five carbons in pentane or "oct-" for eight carbons in octane.
