(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).

- Convert each compound to a Fischer projection, and label each stereogenic center as R or S.arrow_forwardThis is one enantiomer of the molecule. OH H CCH2-CH2-CH3 CH3 Draw the structure of the other enantiomer using wedges and dashes. Click and drag to start drawing a structure.arrow_forwardLocating Stereogenic Centers Locate the stereogenic centers in each drug. Albuterol is a bronchodilator— that is, it widens airways—so it is used to treat asthma. Chloramphenicol is an antibiotic used extensively in developing countries because of its low cost.arrow_forward
- fischer projection fomulaarrow_forwardConsider the two Fischer projections shown . They are NOT of the same molecule. Explain why the molecules shown are NOT the same? Describe how the groups of a Fischer projection are positioned in the ACTUAL molecule (Are the molecules flat in real life, or three-dimensional in real life? If three-dimensional, where exactly are the Hs and OHs positioned when one interprets these projections? Describe why the second molecule is not simply the first molecule flipped over (like a pancake).arrow_forwardRe-draw each Fischer projection formula using wedges and dashed wedgesfor the stereogenic center, and label the center as R or S.arrow_forward
