11. Your task in this step is to draw the Fischer projection of your model of glyceraldehyde. 1) First, align the carbon chain of your model so that it is vertical and the most oxidized carbon is at the top. 2) Next, adjust the carbon chain so that the horizontal groups attached to the second carbon are projected toward you and the vertical groups are projected away. 3) in the diagram below on the LEFT, the carbon chain has been drawn in for you. Draw in the group that is on the left, that which is on the right, that which is at the top, and that which is at the bottom. 4) Now imagine that the structure on the left has been flattened to make it two-dimensional. The result is the Fischer projection of your model of glyceraldehyde. Draw the Fischer projection of your model of glyceraldehyde in the space below and to the RIGHT. Is the structure D- or L-glyceraldehyde? Take your model to your instructor and convince them of your conclusion. C 12. What would be the result of exchanging the two non-carbon groups bonded to the middle carbon in your model of glyceraldehyde? Do these two molecules represent isomers or the same molecule? If isomers, what kind of isomers are they (be specific)? Convince your instructor of your conclusion. 12. Instructor's Initials
