In terms of intermolecular forces why does methanol mix easily with water whilst octane does not?

Hydrogen bridges (C-O-H) in methanol and water (H-O-H) 'like' each other (attraction!) and octane doesn't have any. (H-C and C-C are covalent, non-polar).

What type of intermolecular forces are dominant in octane?
London Dispersion Forces
Will CaCl2 dissolve in octane?
Sodium chloride (NaCl) is not soluble in octane (C8H18). Sodium chloride is only soluble in water (H2O), methanol (CH4O), formic acid (CH2O2), formamide (CH3NO), glycerol(C3H8O3), propelyne glycol (C3H8O2), and ammonia (NH3).
Is methyl octane alcohol alkane or alkenes?
Alcohol is an Oxygen atom double-bonded to a carbonyl group. As such, there is no such thing as 'Methyl Octane Alcohol'. However, there is Methyl Alcohol and Octyl Alcohol. Please edit your question. Also: If you are asking if Methyl Alcohol is miscible (dissoluble) in octane, it is. Alkanes are hydrocarbons only, so both octane and the methyl group in methanol (methyl alcohol) are alkanes.
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?
hexane and octane is easier to separate than hexane and heptane because the difference in their boiling points is greater thus hexane will distill out of solution more completely before octane
Is it possible to change propane to octane?
It depends on which of the 24 isomers of octane you are after.
What type of intermolecular forces are dominant in octane?
London Dispersion Forces
What is the octane rating of methanol?
The octane rating of methanol depends on the octane rating scale measurement type used, n-Heptane is the zero point of the octane rating scale then the octane rating of methanol is 115
Rank the following in order of increasing solubility in water Methanol. CH3OH Octane C8H18 Carbon tetrachloride CCl4?
Octane < Carbon tetrachloride < Methanol
What kind of intermolecular forces exist between octane molecules?
The bonding is covalent and there are also some weaker forces. However, around the ketone group there is polarity.
Why does octane have a higher boiling point then water?
Octane is a straight chain molecule with a large surface area and stacks easily with other octane molecules. This increases the strength of the London dispersion forces that keep the octane molecules attracted to each other. The London dispersion forces on octane are greater than for smaller straight chain molecules because octane is both heavier and has more electrons that make it more polarizable.
1989 Suzuki Vitara fuel type?
can run any type of fuel. no less than 91 octane unleaded and i think 86 octane leaded. also can run higher octane and a fuel mixture of 10% ethanol or 5% methanol.
What type of inter molecular forces predominates in octane?
van der Waals forces of attraction
Which answer lists the substances in order of decreasing solubility in water?
Hexane < Butanol < Ethanol Octane < Carbon tetrachloride < Methanol
Will CaCl2 dissolve in octane?

How does molecule size affect boiling point?
With a bigger size there are stronger London forces. London forces are also known as Dispersion forces and van der Waal forces. These forces become stronger as the size of the molecule increases. Butane, C4H10, is a gas with a relative size of 58 and a boiling point of ~ -1 ºC. Octane, C8H18, is a liquid with a relative size of 114 and a boiling point of 125 ºC. The two molecules differ in size only but as octane is bigger it has a higher boiling point due to the dispersion forces.
Is it harder to ignite a lower or higher-octane gasoline?
It is harder to ignite higher octane gasoline - the octane rating expresses the compound's resistance to pre-ignition (often called "ping") Low octane fuels tend to 'ping' more than high octane fuels because they ignite more easily.
