Why are cracking large hydrocarbon molecules more useful than the original large molecules?

There is more demand for smaller molecules because they can make up more fuels and plastics. There is less demand for the larger molecules.

What is achieved in the process of cracking?
For anyone who has seen the previous answer ignore the immature remark. "Fuels made from oil mixtures containing large hydrocarbon molecules are not efficient. They do not flow easily and are difficult to ignite. Crude oil often contains too many large hydrocarbon molecules and not enough small hydrocarbon molecules to meet demand - this is where cracking comes in. Cracking allows large hydrocarbon molecules to be broken down into smaller, more useful hydrocarbon molecules. Fractions containing large hydrocarbon molecules are vaporized and passed over a hot catalyst. This breaks chemical bonds in the molecules, and forms smaller hydrocarbon molecules. Cracking is an example of a thermal decomposition reaction." Sources:http://www.bbc.co.uk.education2020.us/
Breaking of a larger hydrocarbon molecule into a smaller one by heating in the presence of a catalyst is called?
Cracking , Cracking is the name given to breaking up large hydrocarbon molecules into smaller and more useful bits. This is achieved by using high pressures and temperatures without a catalyst, or lower temperatures and pressures in the presence of a catalyst.
What is a process where molecules are split into smaller more useful molecules?
The process is called cracking. The best way of breaking them up uses heat and a catalyst, so we call this catalyst cracking.
The controlled process by which hydrocarbons are broken down or rearranged into smaller more useful molecules is called?
Cracking
Explain how the size of hydrocarobon molecules affects the strength of intermolecular forces?
The longer the hydrocarbon chain, the stronger the intermolecular forces. This leads to higher boiling point, and these chains are likely to be less useful.
Why is cracking useful?
cracking is useful because large hydrocarbon molecules are broken into smaller ones. And these are needed for petrol and are more reactive.

What is cracking used for?
The cracking is used to breaks down big hydrocarbon into smaller ones and make more useful.

Why is hydrocarbon important?
it makes smaller molecules which is more useful.

What type of reaction is cracking?
Cracking is the name given to breaking up large hydrocarbon molecules into smaller and more useful bits. This is achieved by using high pressures and temperatures without a catalyst, or lower temperatures and pressures in the presence of a catalyst. The source of the large hydrocarbon molecules is often the naphtha fraction or the gas oil fraction from the fractional distillation of crude oil (petroleum). These fractions are obtained from the distillation process as liquids, but are re-vaporised before cracking. There isn't any single unique reaction happening in the cracker. The hydrocarbon molecules are broken up in a fairly random way to produce mixtures of smaller hydrocarbons, some of which have carbon-carbon double bonds. One possible reaction involving the hydrocarbon C15H32 might be:

How is cracking useful in an oil refinery?
modern tech is to expensive so cracking IS USED BECAUSE IT IS CHEAP AND EASY
What is a cracking of a oil fraction?
It is when you break large hydrocarbons/alkanes, into smaller more useful alkanes/alkenes. For example a large hydrocarbon in crude oil is Bitumen. By passing this substance over a hot catalyst, you can break it down into smaller hydrocarbons such as Petrol or Diesel
Why is cracking used in the oil industry?
cracking wastes almost nothing and therefore is useful, cracking rearanges the carbon molecule that are big into smaller using therma decomposition,idiot;)
