Conformational Analysis Conformation: Alternate 3D shapes of organic molecules arising from  rotation around single bonds. Molecules in “real” time! http://tigger.uic.edu/~kbruzik/images/butane.mov http://www.youtube.com/watch?v=V2pr7e9g3E4  (ethane – cold) Would one conformation be favored over another? Why?  STRAIN!!!  Strain is the internal energy of a structure due to a distortion. It  is a “high energy state”, causes instability, and is energy with which we  can do work or cause reactions to happen! What types of conformations are possible?  Use Newman projections V. Patman 2 Thurs 2.10.11

Conformations Use Newman projections  - view molecule down axis of a C-C bond.  It may be easier to view/draw via sawhorse projection first!  How to draw ethane in a Newman projection V. Patman 3 Thurs 2.10.11
