Consider pentane, C5H12. Looking through the internal C3-C4single bond, draw thesix Newman projections (where the angle between two bonds as you look through the C3and C4bond is either 0°or 60°of the different conformations. Label the conformers/rotamers using I, II, etc. a.Which conformer is the most stable? the least stable? b.Which rotamer is the anticonformer? the gaucheconformer? c.Draw the anticonformer in saw horse projection.
