Study Notes
Stereochemistry
- Enantiomers are stereoisomers that are non-superposable mirror images of each other.
Chirality
- A chiral molecule is a molecule that cannot be superimposed on its mirror image.
Mixtures
- A racemic mixture is a mixture containing equal amounts of a pair of enantiomers.
Configuration Determination
- The absolute configuration (R or S) of a compound is determined by the arrangement of atoms in space.
Enantiomer Characteristics
- Enantiomers are distinguished from each other by their ability to rotate plane-polarized light in opposite directions.
Structural Isomerism
- Structural isomers are isomers that have the same molecular formula but differ in the arrangement of the carbon chain.
Positional Isomerism
- Positional isomers are isomers that differ in the position of the functional groups.
Functional Group Isomerism
- Functional group isomers are isomers that differ in the functional groups themselves.
Stereoisomerism
- Stereoisomers that are not mirror images of each other fall into the category of diastereomers.
