2,2-Dimethylbutane, trivially known as neohexane, is an organic compound with formula C6H14 or (H3C-)3-C-CH2-CH3. It is therefore an alkane, indeed the most compact and branched of the hexane isomers — the only one with a quaternary carbon and a butane (C4) backbone. WebA Gauche conformation is a specific type of staggered conformation. If one is looking at an eclipsed conformation, then it's not staggered.

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 ... WebThe conformations corresponding to the 120 and 240 are: a) Staggered, less stable than the conformation at 180. b) Staggered, more stable than the conformation at 0. c) Eclipsed, more stable than the conformation at 180. d) Eclipsed, more stable than the conformation at 0. e)Two of the above are true.
