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.
How are hydrocarbon molecules separated?
Hydrocarbon molecules can be separated through processes such as distillation, which takes advantage of differences in boiling points, or through techniques like chromatography, which separates compounds based on their affinity for a stationary phase. Additionally, techniques like fractional distillation or fractional crystallization are used to separate hydrocarbons based on differences in their physical properties.
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. =)
What is fractional distillation distillation and cracking?
fractional distillation is used to separate fuels from crude oils they all have different boiling points so they can be separated easily cracking is when longer chains of hydrocarbons after broken down to make shorter ones which burn more easily.
How crude oil is separated into useful fraction?
Crude oil is separated into different substances with similar boiling points. The substances in crude oil can be separated using fractional distillation. The crude oil is evaporated and its vapours are allowed to condense at different temperatures in the fractionating column. Each fraction contains hydrocarbon molecules with a similar number of carbon atoms

How are the hydrocarbons in petrotuem separated into fractions?
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.

What small hydrocarbon molecules form polymers?
Monomers are small hydrocarbon molecules that form polymers.
Does longer hydrocarbon molecules have higher boiling points than short hydrocarbon molecules?
yes

Is motor oil compound?
Yes, motor oil is a compound, but actually it is a mixture of a number of compounds. There are a lot of different hydrocarbon molecules that make up motor oil. Some are the "mixed bag" of hydrocarbons that are the out-take from the cracker (the fractional distillation column or tower) during refining, and some others are the ones that are "added into" the mix by the petrochemist who is formulating the motor oil.
What does fractional distillation mean in chemistry?
Fractional distillation is a manufacturing process that separates the different components (i.e. fractions 1/2 in a chemical mixture according to their different boiling points. The liquid is raised to boiling and vapors pass through a tubular column where temperature is gradually lowered along its length. Components (fractions) with a higher boiling point condense on the column and return to the solution. Fractions with a lower boiling point pass through the column and are collected. Gasoline, kerosene and naphtha are fractions separated from crude oil using fractional distillation.Here's more in simple,the basic principle of fractional distillation is of using the different boiling points of elements(parts) in a compound(a mixture). A fractional distillation process is done in a cylinder which has different compartments having different temperature points. When the mixture is kept in the cylinder, the elements which have the same boiling point as in the compartment it is in, it vaporizes and moves out through a pipe. The mixture goes on vaporizing as the temperature increases and at last all the elements are removed in separated drums where they are condensed and brought back to their normal state.Another way of putting it is:Fractional distillation differs from distillation only in that it separates a mixture into a number of different parts, called fractions. A tall column is fitted above the mixture, with several condensers coming off at different heights. The column is hot at the bottom and cool at the top. Substances with high boiling points condense at the bottom and substances with low boiling points condense at the top. Like distillation, fractional distillation works because the different substances in the mixture have different boiling points.The simplest way is:Fractional distillation is a form of distillation which is used when more than two liquids with different boiling points are to be separated.
What are the different kinds of forms?
They are formed in the fractional distillation of fossil fuels. They are made up of carbon and hydrogen atoms, and thus can range from small molecules such as methane (CH4) or octane (C8H18) to large macromolecules.
What are two types of detergent molecule?
The most probable type of a molecules in the detergents is the hydrocarbon molecules and the sodium molecules. The sodium molecules binds to water while the hydrocarbon molecule binds to grease.
