WebIt is just that the staggered conformations are more energetically favored. In a system where there is ample energy to allow ethane to surpass the energy barrier necessary to get it into a eclipsed position, then at any given time you will find ethanes adopting a eclipsed conformation. However, given that staggered is more favored and is more ...

WebA Gauche conformation is a specific type of staggered conformation. If one is looking at an eclipsed conformation, then it's not staggered. I think, though I'm not sure, that the higher energy (3.8 kJ/mol) of a gauche conformation (as opposed to a regular staggered) is a result of the same forces that cause higher energy (11 kJ/mol) of two eclipsed methyl …
