1. Identify any meso compounds and label any stereocenter R or S.
Relationships
Predict whether they are same, enantiomers, diastereomers, constitutional isomers, or not even isomers.
Identify any meso compounds and label any stereocenter R or S.
This is best when downloaded
and viewed in the slide show view in powerpoint due to the animations.

2. Basic Relationships Same Constitutional Isomers Diastereomers
conformations, resonance structures, superimposable structures
Constitutional Isomers
same formula, different connectivity
Diastereomers
same formula, same connectivity, different interatom distances

3. Basic Relationships Diastereomers Enantiomers
same formula, same connectivity, different interatom distances
Enantiomers
same formula, same connectivity, same interatom distances
non-superimposable mirror images
