WebWe have only two for this conformation, so only two gauche interactions. That would be a total of 7.6 kilojoules per mole, which is the lowest energy, so this is the most stable conformation. In part B, our goal is to draw the least stable conformation, and we know that the least stable conformation is the one that's the highest in energy.

WebSo in general, the staggered conformation is going to be more stable. It's going to have a lower potential energy.
