"Web4.1.1 Conformation. At a molecular level, a property of σ (sigma) bonds in alkane is that the bonds keep on rotating. For the example of ethane (CH 3 CH 3 ), one methyl (CH 3) group is able to rotate around the C-C bond freely without any obstacles. It is highly recommended that the molecular model is used here to “see” the bond rotation. " - Compare carbon carbon bond rotation
