How is propene obtained from crude oil?
Propene is obtained from crude oil through a process called steam cracking, where long-chain hydrocarbons in crude oil are broken down into smaller molecules such as propene. This process involves heating the crude oil to high temperatures in the presence of steam, which causes the hydrocarbons to undergo thermal decomposition and form propene along with other byproducts.
How can you make monomer molecules unsaturated?
That depends what the monomer is. Most unsaturated monomers are manufactured commercially from crude oil. Ethene, for instance, is made by cracking the gas oil fraction of crude oil. Vinyl chloride is then made from ethene. Styrene is made from benzene and ethene.
Why does crude Oil not dissolve in water?
Crude oil is hydrophobic, which means it repels water and is not soluble in it. This is due to the nonpolar nature of the hydrocarbon molecules in crude oil, which do not interact well with the polar molecules in water. As a result, crude oil will not dissolve in water but will float on its surface.
What does crude oil contain?
Crude oil mainly contains hydrocarbons, which are compounds made of hydrogen and carbon atoms. It also may contain small amounts of sulfur, nitrogen, and other impurities. The composition can vary depending on the source of the oil.
What is the connection between the size of the molecules in crude oil and their condensing or boiling point's?
Smaller molecules have a lower boiling point, and larger molecules have a higher boiling point. Source: Learnt this in class today.
Which fraction in the fractional distillation of crude oil has the longest chain molecule?
The fraction with the longest chain molecules in the fractional distillation of crude oil is the residue left behind after all other fractions have been collected. This residue contains the heaviest and longest hydrocarbon molecules, such as those found in bitumen and pitch.
Did crude oil means petroleum?
Petroleum is refined from crude oil and is but one fraction only
What is the fraction used for jet fuel out crude oil?
Jet fuel is typically composed of hydrocarbons derived from crude oil. The fraction of crude oil used for jet fuel production is known as kerosene, which is a distillation product in the mid-range of the crude oil distillation process. Because jet fuel is a specialized product, only a small fraction of the total crude oil distillation is used to produce it.
How is propene obtained from crude oil?
Propene is obtained from crude oil through a process called steam cracking, where long-chain hydrocarbons in crude oil are broken down into smaller molecules such as propene. This process involves heating the crude oil to high temperatures in the presence of steam, which causes the hydrocarbons to undergo thermal decomposition and form propene along with other byproducts.

Why is cracking used in crude oil or petroleum refinement?
Cracking is used in crude oil or petroleum refinement to break down larger hydrocarbon molecules into smaller, more valuable ones, such as gasoline and diesel. This process helps meet the demand for lighter fuels, which are in higher demand compared to heavier fractions. By cracking, refineries can maximize the production of valuable products from each barrel of crude oil.
What is a fraction in crude oil?
A fraction in crude oil refers to a component that is separated from the whole crude oil through a process known as fractional distillation. Crude oil is made up of different hydrocarbons with varying boiling points, and when heated, these components can be separated into fractions such as gasoline, diesel, and jet fuel based on their boiling points.
Why does crude Oil not dissolve in water?
Crude oil is hydrophobic, which means it repels water and is not soluble in it. This is due to the nonpolar nature of the hydrocarbon molecules in crude oil, which do not interact well with the polar molecules in water. As a result, crude oil will not dissolve in water but will float on its surface.
How crude oil is separated into useful fraction?
Crude oil is separated into useful fractions through a process called fractional distillation. The crude oil is heated until it vaporizes, and then it is passed through a fractional distillation column, where different fractions with different boiling points are collected at various levels of the column based on their boiling points. This process allows for the separation of crude oil into various products such as gasoline, diesel, and jet fuel.
Why are fractions from crude oil cracked?
Fractions from crude oil are cracked to break down larger hydrocarbon molecules into smaller, more valuable ones. This process increases the amount of useful products like gasoline, diesel, and jet fuel that can be derived from crude oil. Cracking also helps to meet the demand for lighter, higher-quality fuels.
What is the equation for cracking in crude oil?
The general equation for the cracking of crude oil involves the breaking of larger hydrocarbon molecules into smaller ones. It can be represented as: nCₓH₂y → C₍a₁₎H₍b₁₎ + C₍a₂₎H₍b₂₎ + ... + C₍aₙ₎H₍bₙ₎, where nCxHy represents a larger hydrocarbon molecule breaking down into smaller hydrocarbon molecules with different carbon (C) and hydrogen (H) compositions.
Does crude oil have a low viscosity fraction?
Yes, crude oil contains various fractions with different viscosities. Some fractions, such as light crude oil, have low viscosity, while others, such as heavy crude oil, have high viscosity. The viscosity of crude oil can affect its flow characteristics and processing requirements.
