Conformations can be described by dihedral angles, which are used to determine the placements of atoms and their distance from one another and can be visualized by Newman projections. A dihedral angle can indicate staggered and eclipsed orientation, but is specifically used to determine the angle between two specific atoms on opposing carbons. Different conformatio… WebBut if the molecule is in eclipsed confirmation and is even slightly above 0k then it will soon wiggle, and fall back to a staggered conformation because the forces are no longer axial. A perfect eclipsed formation is an unstable equilibria like a needle standing on it's point. In the last video, we visualized an ethane molecule with a Newman Projection. …

WebJun 4, 2015 · A staggered conformer is more stable than an eclipsed conformer as the latter involves unfavourable energy interactions between atoms.
