ALKENES CAN BE MANUFACTURED BY

  • A. the combustion of alkanes
  • B. the cracking of hydrocarbons ✓
  • C. polymerization reactions
  • D. addition of hydrogen to unsaturated vegetable oils

 

Cracking is a chemical process used in petroleum refining to break down larger hydrocarbon molecules into smaller and more useful ones. This process involves applying high temperatures and/or catalytic conditions to break the long carbon chains of hydrocarbons into shorter ones, resulting in a mixture of products, including alkenes. Alkenes are unsaturated hydrocarbons that contain carbon-carbon double bonds, and they are produced as a result of the cracking process.

In other words, Alkenes can be manufactured by the cracking of hydrocarbons. Cracking is a process in which larger hydrocarbon molecules are broken down into smaller, more useful molecules such as alkenes and alkanes. This process is commonly used in the petroleum industry to produce valuable products like ethylene and propylene, which are important building blocks for various chemicals and plastics.
