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 ... WebBased on NMR studies at low temperature, these two conformations are not equally stable, the staggered conformation is about 13.8 kJ/mol more stable than the eclipsed conformation. At room temperature, this energy difference is negligible, that is, a typical molecular collision supplies much more energy, and the two conformations rapidly ...

WebSep 7, 2024 · In Staggered Conformation, no group lies parallel to another one in a compound. In Gauche form, More bulky and less bulky groups lie parallel to each other. Thus one can say Staggeres form is the most stable Conformer. BUT in few cases, Gauche form is more stable due to intermolecular hydrogen bonding, etc. Table of Contents show.

Further, it is the vicinal hyperconjugative effects that keep the molecule in the staggered conformation.

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.columbia.edu/itc/chemistry/chem-c140499/chemgate/module_organic.pdf

WebThis allows us to see all the eclipsed hydrogens and all of the torsional strain, so the boat conformation is much higher in energy compared to the chair conformation, the chair conformation is the lowest in energy.
