Because the anti conformation is lowest in energy (and also simply for ease of drawing), it is conventional to draw open-chain alkanes in a ‘zigzag’ form, which implies anti conformation at all carbon-carbon bonds. L-Erythrose By convention: Fischer projections are eclipsed with the most oxidized carbon at the top (C-1). This one is convenient becuase F and OH are top and bottom, but I don't know how it would be done if the OH was top too at the back, but anyways. The leaving group and the hydrogen can also be periplanar even if they are not in the plane of the page. 2,2-dimethylpentane. Fischer Projection Formulas.
