Because hydrocarbons are a whole (referring to fractions) and the molecules (represent the fraction) that make up the whole are carbon and hydrogen CH4 this means that the hydrocarbons consist of 1carbon and 4 hydrogen molecules.

How is crude made into products?
Crude oil contains mixture of various types of hydrocarbons. The hydrocarbons are separated by fractional distillation. Different hydrocarbons have different boiling points and therefore after crude oil is heated, shorter chains of hydrocarbons which have lower boiling point will become gas and can be easily separated one by one from hydrocarbons with shorter chains to longer chains. The brief products are Petroleum Gas, Gasoline, Kerosone, Heating Oil, Lubricating Oil and Bitumen in order of increasing molecular size.
What mixture separated by fractional distillation?
fractional distillation is used in oil refineries to separate crude oil into useful substances (or fractions) having different hydrocarbons of different boiling points.
Is oil and water a pure substance?
Crude oil is a mixture of short to long chain hydrocarbons. It has to be separated into many different fractions to become usable. It may also contain mineral impurities due to it being underground
What is used to separate different fractions in crude oil?
Typically they are separated in a fractional distillation tower.
Is cure oil a hetero mixture or a homo mixture?
Crude oil is a vast mixture of hydrocarbons of different lengths, Thus making it a "hetero" mixture.These hydrocarbons can be separated quite easily by fractional distillation which can isolate quite accurately the difference in their boiling points!
What do you mean by a fraction of petroleum?
Petroluem does not consist of a single substance but is a mixture of many substances - mostly several different hydrocarbons. These are separated by a process called fractional distillation. These different components are called fractions.
Is crude oil a substance?
Crude oil is a mixture of short to long chain hydrocarbons. It has to be separated into many different fractions to become usable. It may also contain mineral impurities due to it being underground
What physical property of hydrocarbons is used for fractional distillation?
If the hydrocarbons are in the liquid state then their differential boiling points are used in separation - fractional distillation. Some hydrocarbons are also separated by their differential solubility in some organic solvents. =)
How is it possible to increase the yield of light hydrocarbons from crude petroleum?
Increasing the yield of light hydrocarbons in crude petroleum is only possible by refining the petroleum in a huge chemical plant, so you will not be able to do it in your home. The refining process itself is very complicated: crude oil is separated into different fractions by distillation which are later treated further to convert them into new compound mixtures.
How is naphtha fraction separated from the other fractions?
By fractional distillation.

Why crude oil is separated into different fractions?
Unless you own a cargo ship and run it on crude oil - some operators do - it has to be separated into fractions before it's usable.
How are different hydrocarbons separated by fractional distillation at an oil refinery?
Separation is based on the differences between boiling points.
What mixture separated by fractional distillation?
fractional distillation is used in oil refineries to separate crude oil into useful substances (or fractions) having different hydrocarbons of different boiling points.
Is crude oil compound or mixture?
Crude oil is a mixture of compounds called hydrocarbons. Many useful materials can be produced from crude oil. It can be separated into different fractions using fractional distillation, and some of these can be used as fuels. Unfortunately, there are environmental consequences when fossil fuels such as crude oil and its products are used.
Is oil and water a pure substance?
Crude oil is a mixture of short to long chain hydrocarbons. It has to be separated into many different fractions to become usable. It may also contain mineral impurities due to it being underground
How is fuel broken down into smaller more useful molecules such as gasoline petrol?
Crude oil is split into fractions using fractional distillation The crude oil is heated and separated based on boiling points. This process produces more Bitumen and other heavier fractions than lighter fractions such as diesel, naphtha and kerosene. To produce more fuel, catalytic cracking is used. In this process heavy hydrocarbons are broken down into lighter ones; For example hexane an alkane, it is converted in to butane and ethene. C6H14 -> C2H4 + C4H10
