SpletHydrocarbons can be used as fuels. Some short chain hydrocarbons can be used as fuels. For example, petrol can be used in cars. There is a high demand for fuels with small molecules. Hydrocarbons can form polymers. Other short chain hydrocarbons, such as alkenes, formed from thermal cracking, can go on to form polymers. SpletAlkanes (Saturated Hydrocarbons) A saturated hydrocarbon, also known as an alkane, is a hydrocarbon in which all bonds between the carbon atoms are single bonds. The general chemical formula for an alkane is CnH2n+2. Alkanes in which the carbon atoms form long chains are called straight-chain alkanes. Examples of the first ten alkanes

Short-chain alkanes are primarily used fuels. Alkenes are used to make polymers and as a chemical feedstock. Cracking can be thermal or catalytic. Both types of cracking require harsh conditions to break the ...

SpletCracking converts long chain hydrocarbons into short chain hydrocarbons. Long-chain alkanes are broken down into alkanes and alkenes of shorter length. Crude oil contains a surplus long chains. Shorter chain hydrocarbons are in greater demand, e.g. petrol. Cracking also produces alkenes which are used in making polymers and ethanol. Related …
