The smallest alkane with such a chemical bond, ethane, exists as an infinite number of conformations with respect to rotation around the C–C bond. Two of these are recognised as energy minimum (staggered conformation) and energy maximum (eclipsed conformation) forms. The existence of specific co… WebThe less favored conformation is the gauche-conformation in which methyl groups are at an angle of 60°. Because of a fully eclipsed conformation, the two gauche conformations are separated at 60° and 300°, while the two partly eclipsed confirmation becomes a barrier between the anti and gauche forms. segal documents meaning
