Construct a molecule of butane, CH3CH2CH2CH3 and holding one CH3 group at the end of the molecule, look down the C2 - C3 axis as you rotate the CH3 group at the opposite end. Draw Newman Projections of all of the significantly different conformations of butane and comment of the different symmetry elements of these conformation.
