Petrol is obtained from crude oil by fractional distillation and subsequent mixing of some of the fractions to obtain the desired properties. There are seasonal differences in petrol to facilitate vehicle operation under different climactic conditions. Some of the fractions for the petrol may be obtained by "cracking" higher molecular weight fractions to lower molecular weights. Some impurities, like sulfur, and some unsaturation of the fraction may be removed by treatment with hydrogen which replaces the impurity on the hydrocarbon molecule or adds hydrogen to the molecule to make it more stable. Some of the fractions may be treated to rearrange some of the molecules to make a more desireable product. It is a complex process that is highly dependant on the crude source, desired products, time of year, and the configuration of the refinery. From the same crude may come: fractions for making plastics, rubber, heating oil, diesel and gasoline fuels, lpg fuel, lubricants, solvents, petroleum coke, elemental sulfur, asphalt, bunker fuel oil, etc.

Is petrol a mixture of alkanes and alkenes?
Petrol, also called gasoline, is a mixture of different hydrocarbons, mostly alkanes.
Is petrol a mixture or a substance?
mixture of several fractions of crude oil, plus various additives.
Is crude oil a mixture?
It is a mixture of hydrocarbons, which can be separated by fractional distillation. Oil is NOT an element.
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 chemicals are present in petrol?
Petrol is a mixture of Hydrocarbons (obtained from crude oil) through the process of fractional distillation. Fractional distillation basically involves heating a mixture at different temperatures to obtain individual compounds. Crude oil is not a compound, it is arbitrary mixture that contains myriad hydrocarbons. The shorter hydrocarbons will boil at the lowest temperature (shorter chain = less energy) and the longer the hydrocarbon chain gets (a general measure of the carbons in the chain) the more energy it takes to boil it. Petrol generally contains between 6 and 12 carbon chain length hydrocarbons. I can't give specific names because hydrocarbons comes in saturated, unsaturated, cyclic, aromatic, xylene forms. Read up on some Organic Chemistry to get a brief overview of these. Petrol can contain carbon chain lengths of 6 and 12 that could be anyone of those hydrocarbons mentioned above. Each has its own properties that affect the properties of petrol in general, mainly affecting energy density of the fuel. Due to double bonds, triple bonds, cyclic structures etc.
Is petrol homogeneous or hetrogeneous?
Petrol is a homogeneous mixture of various hydrocarbons (mostly octane, C8H18.)
Is petrol a mixture of alkanes and alkenes?
Petrol, also called gasoline, is a mixture of different hydrocarbons, mostly alkanes.
Mixture of hydrocarbons that are used for fuels?
I am pretty sure the answer is hydrocarbons.
What meant by crude petrol?
Mixture of naturally occurring hydrocarbons that is refined into diesel, gasoline ------------------------- Crude petrol is petrol as extracted, without any treatment.
Is petrol a mixture or a substance?
mixture of several fractions of crude oil, plus various additives.
Chemical formula forpetrol?
Petrol is a mixture of various hydrocarbons, so its correct formula cannot be isolated
What is benzine?
it is a colourless, flammable, liquid mixture of hydrocarbons obtained by distilling petrol. It is used in cleaning and dying and as a motor fuel

What substances is petrol made of?
It's a collection (quite variable) of low weight hydrocarbons; most with carbon counts between 5 and 8.
How is oil made into petrol?
By adding hydrocarbons
