In the study of conformational isomerism, the Gauche effect is an atypical situation where a gauche conformation (groups separated by a torsion angle of approximately 60°) is more stable than the anti conformation (180°). There are both steric and electronic effects that affect the relative stability of conformers. Ordinarily, steric effects predominate to place large substituents fa… WebIn Newman projection, gauche is the relationship between two atoms or groups whose dihedral angle is 60 °. ...
