Answer #1

To draw Fisher Projection structure of any structure uses the following rules:

  1. In Fischer projection bonds rotated by 180 degrees without changing its meaning.
  2. When in a Fischer projection bonds rotated by 90 degrees it changes the configuration to the enantiomer.
  3. In Fischer projection generally to find the enantiomer of a molecule exchange the right and left horizontal bonds.
  4. In Fischer projection a meso compound show a symmetric about the line, which is horizontal through the center of the molecule .
