WebEclipsed conformer can be converted back into gauche conformation by rotating it 60 degrees and when an eclipsed is rotated by 180 degrees it forms anti- conformer. Rotation of anti butane by 120 degrees again leads to the formation of the gauche conformed. Ranking of Conformation Isomers. Webthis rotational barrier: A steric repulsion in the eclipsed conformation [2–4,9–14] and an enhanced stabilization of the staggered conformation due to hyperconjugation [5,8,15–22]. The steric effect has its origin in the fact that atoms in molecules occupy a certain amount of space, resulting in changes in shape, energy, and reactivity.
