Definition
Have the same molecular formula and the same connectivity but different orientations of their atoms in space
Ex: Cis,trans isomers in cycloalkanes |

Term

Definition
| Stereoisomerism in which the isomers have the same structure (same linkages between atoms) but different spatial arrangements of the atoms |
|

Term
|
Definition
| Nonsuperposable mirror images (refers to the relationship between a pair of objects) -Must be chiral objects |
|
|
Term
|
Definition
| a carbon atom with four different groups bonded to it and lacks the two key symmetry elements |
|
|
Term
|
Definition
| an atom about which exchange of two groups produces a stereoisomer |
|
|
Term
|
Definition
Stereoisomers that are not mirror images of one another
-Can be chiral or achiral |
|
|
Term
|
Definition
| A form of stereoisomerism in which the isomers can be interconverted exclusively by rotations about formally single bonds |
|
|
Term
|
Definition
| Isomers which lack a chiral center but do not interconvert because of hindered rotation |
|
