"WebThis conformation has the highest energy. It’s the least stable. When the two largest groups are staggered and are at 60°, we call this conformation gauche from the french word meaning “to the left.” When the two largest groups are directly opposite to each other, we call it an anti conformation.

WebSo in general, the staggered conformation is going to be more stable. It's going to have a lower potential energy. You can imagine that if you start with an eclipsed conformation, these guys are all going to want to get away from each other. So it's kind of like this is the wound conformation. It has higher potential energy. WebStudy with Quizlet and memorize flashcards containing terms like There are 8 isomers that have the molecular formula C5H11Br.
