Chiral carbons =
|
carbons with four different groups attached are chiral.
The mirror image will be a different compound (enantiomer). has chiral carbons, no plane of symmetry |
|
Achiral compounds
|
molecules can be superimposed
- a molecule that has a plane of symmetry. |
|
Isomers =
|
compounds with the same formula
|
|
Constitutional isomers =
|
same formula, but different in the way the atoms are attached
CH3OCH3 CH3CH2OH |
|
Stereoisomers =
|
same formula, same point of attachment, difference in spatial arrangement
|
|
Enantiomers =
|
nonsuperimposable mirror images, different molecules with different properties.
- have the following properties: -Same boiling point -Same melting point -Different rotation for the plane of polarized light |
|
Conformation isomers =
|
same formula, same point of attachment, difference in spatial arrangement, and interconverts at room temperature
-same formula, same point of attachment, difference in spatial arrangement, and cannot interconvert at room temperature |
|
Cahn-Ingold-Prelog Rule 1
|
Compare the first atoms. The atom with the highest atomic weight has the highest priority.
|
|
Cahn-Ingold-Prelog Rule 2
|
If the first atoms are the same, compare the next atoms.
|
|
Cahn-Ingold-Prelog Rule 3
|
For double bonds, add one set of imaginary atoms. For triple bonds, add two sets of imaginary atoms.
