What is always produced in a cracking reaction?

In a cracking reaction, smaller hydrocarbons are produced from larger hydrocarbons, typically resulting in alkanes and alkenes. This process often generates valuable products like gasoline and petrochemical feedstocks. Additionally, it may produce byproducts such as hydrogen gas and other light hydrocarbons. Overall, cracking is a key process in refining crude oil to create usable fuels and chemicals.
