Organic Chemistry Chapter 5

Front 1

Chiral carbons =

Back 1

carbons with four different groups attached are chiral.
The mirror image will be a different compound (enantiomer).
has chiral carbons, no plane of symmetry

Front 2

Achiral compounds

Back 2

molecules can be superimposed
- a molecule that has a plane of symmetry.

Front 3

Isomers =

Back 3

compounds with the same formula

Front 4

Constitutional isomers =

Back 4

same formula, but different in the way the atoms are attached
CH3OCH3 CH3CH2OH

Front 5

Stereoisomers =

Back 5

same formula, same point of attachment, difference in spatial arrangement

Front 6

Enantiomers =

Back 6

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

Front 7

Conformation isomers =

Back 7

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

Front 8

Cahn-Ingold-Prelog Rule 1

Back 8

Compare the first atoms. The atom with the highest atomic weight has the highest priority.

Front 9

Cahn-Ingold-Prelog Rule 2

Back 9

If the first atoms are the same, compare the next atoms.

Front 10

Cahn-Ingold-Prelog Rule 3

Back 10

For double bonds, add one set of imaginary atoms. For triple bonds, add two sets of imaginary atoms.
