WebButane is an alkane with the presence of C-C bonds. Normally, when we rotate the molecule of butane at the axis of the C-C bond, it shows different conformation isomerism. Generally, Butane has four conformation isomers which are fully eclipsed, gauche, eclipsed, and anti butane conformational isomers. Lets us discuss these isomers below.

WebFor example, n-butane has two possible conformations, anti and gauche. The anti conformation is more stable by 0.9 kcal mol −1.
