The Gauche effect refers to a conformational preference observed in certain organic molecules, particularly in butane and other alkanes. In these molecules, the Gauche conformation is one where two substituents (or hydrogen atoms) are positioned approximately 60 degrees apart, which can lead to steric interactions and influences on the overall stability of the molecule.
