Constitutional Isomers
same molecular formula, different connectivity
Stereoisomers (Enantiomers and Diastereoisomers)
Same formula, same connectivity, DIFFERENT 3D Orientation (Hands)
Enantiomers (R/S naming)
Mirror images that do NOT overlap (superimpose), same connectivity, exact opposite R/S, same
physical properties (bp,melting), DIFFERENT optical rotation of light (opposites)
Diasteroisomers (Cis/Trans/E/Z)
NOT mirror images, different physical properties, do NOT have EXACT opposite R/S, no
relation with optical rotation
, Epimers
diastereomers that differ at only one chiral carbon
Anomers
sugars that are diasteromers, differing only in the position of the hydroxyl at the anomeric
carbon
Meso Compound (SUPERIMPOSABLE)
A compound with chirality centers and an internal plane of symmetry causing it to be an achiral
molecule (at least two chiral centers)
Stereocenters vs Stereoisomers
Stereocenters: how many SINGLE chiral centers in a molecule
Stereoisomers: number of single chiral centers superscripted to 2n formula (2^n); n = number of
chiral centers
Chirality Center (Stereo centers)
Carbon center that contains four unique substituents
Cahn-Ingold-Prelog priority rules
The higher the atomic number, the higher the priority. (Z) Alkene is one where the
highest-priority substituents on each carbon are on the same side of the double bond. (E)
Alkene is one where the highest-priority substituents on each carbon are on the opposite side.

Fischer Projection R/S
4th priority to be on vertical (middle)
