So reviewig the kectures and my notes, I am wondering if their is a difference between torsional strain and an eclipsed conformation? An eclipsed conformation and torsional strain both relate to the highest energy state right, while staggered is the most stable?

Torsional strain is defined as strain caused as the force applied in the gauche conformation rotates the atom or atom group towards another group. Torsional strain is something that occurs during the eclipsed conformation. Torsional strain is an explanation as to why the eclipsed conformation has a greater potential energy than staggered conformations. Staggered have lower energy because it lacks this strain (as well as steric strain) and thus is more stable.
