WebThe staggered form of ethane has the lowest energy. This is because the C-H bonds are furthest from each other, minimizing steric repulsion between the electrons in the bonds, and therefore, stabilizing the molecule. ... At 0° dihedral angles, the C-H groups cover one another to form an eclipsed conformation. This conformation has about 12 kJ ... WebFeb 2, 1998 · Ethane (H3C–CH3) and Substituted Ethane The ethane molecule, C2H6, can exist in both the staggered and eclipsed conformations where the staggered conformation is slightly more stable. The differences in these two conformations for ethane can easily be seen by viewing them both on the screen simultaneously. Look down the C-C

WebThe eclipsed conformation is, therefore, of highest energy and has the lowest stability. Evidently, all the skew form of ethane will have stabilities in between that of staggered and eclipsed conformation. Hence, the relative stabilities of the various conformations of ethane are: Staggered > skew > eclipsed. Conformation of Propane: WebThe existence of a rotational barrier of 2.875 kcal·mol−1 about the C-C bond in ethane has been known for many years [1–9]. There are two main effects that have been regarded as responsible for this rotational barrier: A steric repulsion in the eclipsed conformation [2–4,9–14] and an enhanced matthew bates theology

Assertion :Staggered conformation of ethane is most stable while eclipsed conformation is least stable. Reason: Staggered form has the least torsional strain and the eclipsed form has the maximum torsional strain. Q. Assertion :For C2H6 staggered conformation is more stable than eclipsed. hercules megabubble sds
