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 … WebAug 20, 2014 · The anti conformation has the two methyl groups pointing directly up and down (when looking down the C2-C3 bond), and the gauche conformation has the two methyl groups looking only 60 degrees apart (looking down the C2-C3 bond).
