(a) Interpretation: The more stable chair form of fucose is to be drawn. Concept introduction: In Fischer projection formula, the horizontal and vertical line represents the bonds that are present above and below the plane, respectively. The verticals bonds are represented as dashed wedge and horizontal bonds as dark wedge. The substituents present “up” and “down” in Haworth projection are represented as up and down bonds in chair conformation.
