Mr. Key outlines how to identify, name*, and represent hydrocarbons containing multiple bonds. Cycloalkanes, geometric and structural isomers are also discussed.
*Note that to match the textbook used by my students, when naming hydrocarbons with multiple bonds, the systematic approach of putting the position number before the prefix is used (e.g. 2-butene), rather than the recently preferred IUPAC method (e.g. but-2-ene).
Please note that all questions, comments and critiques are welcome. However, because the primary purpose of these videos is educational for students/educators, the comments are moderated. Any comments that are deemed abusive, inappropriate, or unrelated to the topic matter will not be posted and the user potentially blocked.

![Reaction Theories and Potential Energy Diagrams
NEW FOR 2020!
In this video, @JFRScience s Mr. Key explains:
1. Collision Theory
2. Transition State Theory
3. Potential Energy Diagrams
4. Factors affecting successful collisions (T, [ ], and SA)
5. Catalysts
Please note that the primary purpose of these videos is educational for students/educators. While all feedback, both positive and...hmmm...constructive, is appreciated I do not have the time to moderate or respond to all comments. As a result, comments on these videos have been disabled at least for the near future. Reaction Theories and Potential Energy Diagrams](https://i.ytimg.com/vi/VW4PfumNwSE/mqdefault.jpg)
