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/


The controlled process by which hydrocarbons are broken down or rearranged into smaller more useful molecules is called?

The controlled process by which hydrocarbons are broken down or rearranged into smaller, more useful molecules is called catalytic cracking.


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 the extraction of oil cracking?

Oil cracking is a process used to break down complex hydrocarbons in crude oil into simpler molecules like gasoline and diesel. The extraction of oil cracking involves heating the oil at high temperatures and breaking the larger molecules into smaller ones through thermal or catalytic methods, resulting in a higher yield of useful products.


What is a process where molecules are split into smaller more useful molecules?

The process you are referring to is called chemical degradation or breakdown. By breaking down larger molecules into smaller, more useful molecules, this process helps to release energy, provide building blocks for biosynthesis, or allow for easier excretion of waste products. Key examples include digestion of food in the body or breakdown of organic matter in composting.

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 type of reaction is cracking?

Cracking is a type of thermal decomposition reaction where larger hydrocarbon molecules are broken down into smaller, more useful molecules like alkenes and shorter-chain hydrocarbons. It is commonly used in the petroleum industry to produce gasoline and other valuable compounds from crude oil.


What conditions are needed for cracking of oil fraction?

Cracking of oil fractions requires high temperatures (500-700 degrees Celsius) and the presence of a catalyst to break down larger hydrocarbon molecules into smaller, more useful ones like gasoline and diesel. The process can occur under either high pressure or in the presence of steam to facilitate the reaction.

Why are fractions from crude oil cracked?

To make alkenes, to make alkenes with smaller molecules, to make fuels that are more useful or for which there is more demand.Large hydrocarbons do not burn easily or are less in demand
