Answer:
The alkanes are isolated from natural gas and petroleum. Natural gas contains mainly methane, with smaller amounts of other low‐molecular‐weight alkanes. Petroleum, which is a complex mixture of many compounds, is the main source of all other alkanes.

An alkene is a hydrocarbon containing a carbon–carbon double bond.
- Cracking, a method that uses heat and a catalyst to decompose alkanes, produces alkenes from alkanes in crude oil. The cracking process is significant because it converts less usable alkanes into smaller, more useful alkenes like ethene, which is used as a starting material in the plastics industry.
- It can be produced from chemical reactions in industries for many uses.
