3 types of Fischer Projections:
o I – identical isomer (the same molecule)
o E – enantiomer isomer (mirror image, 90 degree rotation apart, but not identical
o C – constitutional isomer (totally different molecule and arrangements)
“R” is when something is rotated clockwise.
“S” is when something is rotated counterclockwise.

Number of stereoisomers: 2 where n = # of chiral centers.
o Ex: glyceraldehyde has 2 enantiomers.
o Ex: aldotetroses has 4 enantiomers.
If the hydroxyl groups are on the same side as each other, they are cal
