(a)
Interpretation:
Fischer projection for a given molecule needs to be determined.
Concept Introduction:
Fischer Projection is a method of drawing 3-D structures of organic molecules in 2D nature. In this method, all non-terminal bonds are depicted as horizontal or vertical lines.
For a simple molecule consists of one chiral center with four different groups attached (e.g. CHClBrI), the Fischer projection method uses a cross formula to draw the two bonds in the plane. In the Fischer projection, both horizontal bonds come forward (drawn on wedges) and both vertical bonds go behind (on dashed lines).
