WebHowever, in butane (C4H10, the one in this video), the front and back carbons in the Newman projections each have a methyl group, and we use those to identify anti or gauche. This means we an also identify one unique eclipsed situation. If the methyl groups eclipse each other, it's referred to as the totally eclipsed conformation (or sometimes ...

Staggered conformation - Wikipedia

WebStaggered conformations are more stable than eclipsed; Anti conformations are most stable; each gauche interaction costs about 0.9 kcal/mol. From examination of ethane, we know that a CH-CH eclipsing interaction costs 0.9 kcal/mol. We can deduce, then, that each CH-CC eclipsing interaction costs (3.6 kcal/mol - 0.9 kcal/mol)/2 = 1.4 kcal/mol.

Because it is difficult to draw a true staggered Newman projection, it is common to show the bonds slightly askew. Place the substituents attached to the second carbon (C 3) on the back bonds of all three Newman projections. In this example they are 2 CH 3 s and an H. …

WebUsing Newman projections, rotating around a specific bond to reach other conformers is a fairly straightforward task. ... With butane, not all eclipsed conformations are of the same energy, and not all staggered … WebA Gauche conformation is a specific type of staggered conformation. If one is looking at an eclipsed conformation, then it's not staggered. I think, though I'm not sure, that the higher energy (3.8 kJ/mol) of a gauche conformation (as opposed to a regular staggered) is a result of the same forces that cause higher energy (11 kJ/mol) of two eclipsed methyl …
