| Description | Newman projections of ethane conformations & their relative energy differences (not total energies). Conformations form when ethane rotates about one of its single covalent bond. Torsional/dihedral angle is shown on x-axis.
Conformations (according to IUPAC): A: staggered B: eclipsed Valleys of the pink graph are conformations lowest in energy (shown as A). Peaks are conformations highest in energy (shown as B). B is highest & A lowest in energy. A is thus the most stable conformation. Valleys are local energy minima. A can thus be classified as a rotamer (a class of conformers). Peaks are not rotamers, & are caused by repulsive forces of the hydrogens. Source for conformation names & rotamer classification: Pure & Appl. Chem., Vol. 68, No. 12, pp. 2193-2222, 1996.
