Power Point



Key concepts you need to understand:  Valence electrons; Lewis structures; covalent bonds; sigma and pi bonds; single, double, triple bonds; hybridization and molecular geometry; formal charge; drawing organic structures; comparing organic structures (constitutional isomers, identical, different).


Practice Problems:  You should be able to answer these problems after watching the CH-1 videos.  These problems can be found on-line at the web site for Organic Chemistry Practice Problems:
