Scan along the baseline to move rapidly among the models, or click on a point to view a specific conformation (be careful not to disturb the baseline in this case!)


Click on the lowest point on the graph to view the most stable conformation.

 

This energy profile shows the how the potential energy varies with bond angle θ for the Z-allyl silate. The potential energy is high when the molecule is in a conformation where there is a large steric interaction and low when the steric interaction is small.

In the minimum energy conformation the methyl group of the Z-alkene is eclipsed by a hydrogen atom, wheras in the maximum energy conformation it is eclipsed by a more bulky methyl group.
