Gauche vs Anti Conformation in Organic Molecules - Structural Diagrams #142097 (License: Personal Use)

The left diagram illustrates the gauche conformation, where bulky groups are positioned 60° apart on adjacent carbons, resulting in higher torsional strain. The right diagram shows the anti conformation, with groups diametrically opposed (180°), representing the lowest-energy staggered arrangement. Both use solid and dashed wedges to denote 3D spatial orientation in Newman projections.

Used in organic chemistry education and textbooks to explain conformational analysis of alkanes, particularly ethane and butane derivatives; supports learning about rotational isomerism, steric effects, and potential energy diagrams.
