WebStaggered conformation. In organic chemistry, a staggered conformation is a chemical conformation of an ethane -like moiety abcX–Ydef in which the substituents a, b, and c are at the maximum distance from d, e, and f; this requires the torsion angles to be 60°. [1] It is the opposite of an eclipsed conformation, in which those substituents ... WebSep 7, 2024 · In Staggered Conformation, no group lies parallel to another one in a compound.

WebMore complex molecules, such as butane, have more than one possible staggered conformation. The anti conformation of butane is approximately 0.9 kcal mol −1 (3.8 kJ mol −1) more stable than the gauche conformation. Both of these staggered conformations are much more stable than the eclipsed conformations. http://www.chem.ucla.edu/~harding/IGOC/G/gauche.html

Web-For butane: most stable conformation is staggered and anti (methyl grps 180 deg away form each other) o Due to minimal steric repulsion = lowest-energy state o No overlap of atoms along line of sight = staggered o Two largest grps antiperiplanar (same plane, opposite sides) = anti-If staggered conformation is guache largest grps would be 60 … WebIllustrated Glossary of Organic Chemistry. Eclipsed (eclipsed conformation ): Two atoms and/or groups whose dihedral angle is 0 o. In other words, their bonds to the axis of rotation are aligned.
