WebMay 18, 2015 · This is the R isomer. We got it right! Step 3. Draw the skeleton Fischer projection. To convert this to a Fischer projection, draw a vertical line of five carbon atoms, with C-1 at the top and a cross at C-2. Step 4. Attach the H and the Br atoms to the correct sides of the cross. We must look at the molecule from the upper right.
