Organic Chemistry: Alkenes, Alkynes and Isomers

How do we tell organic molecules apart? Discover the basics of alkene and alkyne formulas, bonding, and isomers with a video from JFR Science. The narrator shows examples, adds functional groups, then creates isomers to elaborate on how double bonds affect functional group position.

Instructional Ideas

  • Use the video to teach structure and nomenclature at the same time
  • Plan some practice time after watching until pupils get the hang of it
Classroom Considerations

  • Consider passing out molecular modeling kits and having the class build the molecules along with the narrator
Pros

  • Builds molecules slowly so that pupils can piece together the structure as well as its name
  • Shows isomers both as models and as diagrams to make sure viewers understand how they differ in 3-D space
Cons

  • None
