WebIdentify the eclipsed conformation of ethane among the following: 3. Correctly identify the staggered conformation of ethane drawn as sawhorse projection: 4. Indicate the eclipsed form of ethane ... WebYes, but only when you have a unique functional group to differentiate them. For example, ethane (C2H6), there would be no reason to differentiate between the eclipsed conformations (nor, the anti or gauche, which is why they are collectively referred to as staggered in that situation). However, in butane (C4H10, the one in this video), the front …

WebUnlike ethane and propane that have only two major conformations, butane has more than two conformers. The staggered form of butane in which the bulky methyl groups on the two carbons are placed on opposite sides, that is, at a dihedral angle of 180°, is the lowest energy, most stable form — called the anti conformer. This conformation is stabilized … WebIn the eclipsed conformation, the dihedral angle could be 0, 120, 240 or 360 degrees; in a staggered conformer, the dihedral angle could be 60, 180, 300 degrees. Figure CA2.4. Newman projections showing staggered (left) and eclipsed conformations (right) of ethane. Many conformations of ethane are possible, but not all of these conformations ... WebWhen two C-H bonds are brought into a dihedral angle of zero degrees, their electron clouds experience repulsion, which raises the energy of the molecule.
