Stereoisomers
Enantiomers
Racemic Mixture
1:1 ratio of enantiomers
Optically Pure
Only one enantiomer produced
Optically Active
Chiral molecules
Meso compounds may have stereocenters - still optically inactive - achiral
Stereocenters
Atoms for which the interchange of two substituents gives a stereoisomers
R
S
Chirality
Chiral
Have non-superimposable mirror image isomers
Enantiomers
No internal plane of symmetry
Have enantiomers
Achiral
If it has S and R chiral centers
Meso
Has an internal plane of symmetry
Diastereomers
Determining the relationship between two molecules
Do they have the same molecular formula?
Yes
Do they have the same conductivity?
No
Constitutional Isomers
Yes
Do they have perfect 3D overlap?
Yes
Same molecule
No
Are they mirror-image related?
Yes

No
Not stereoisomers
Max no. stereoisomers = 2^n where n = number of stereocenters
