Hydrocarbon Cracking and Why It Is Done

Let's get cracking! But, what is hydrocarbon cracking? Chemistry scholars learn the how and why of a process that involves breaking long-chain alkanes down into smaller alkanes and an alkene. The narrator shows both common methods, as well as the variety of useful products the process makes.

Classroom Considerations
  • Requires prior knowledge of alkane and alkene chemistry and their nomenclature 
Pros
  • The resource reinforces prior knowledge of the conservation of mass, balanced chemical equations, and use of catalysts
  • Animation helps pupils link the original long-chain alkane to the variety of products that can result from cracking
Cons
  • None
