Chem 112 isomers
Different types of isomers
| Term | Definition |
|---|---|
| structural isomers | different connections between atoms (linkage/coordination) |
| linkage isomer | when a ligand bonds to the central atom using different donor atoms |
| coordination isomers | when the ligand and counterion in a formula change places |
| stereoisomers | same connections between atoms, different spatial arrangements (geometric/optical) |
| geometric isomers | isomers that are not mirror images of one another (cis/trans, fac/mer) |
| cis- isomer | bonds of similar elements on the same side of a central atom |
| trans- isomer | bonds of similar elements on opposite sides of a central atom |
| fac- isomer | bonds of similar elements in the same plane |
| mer- isomer | bonds of similar elements in different planes |
| optical isomers | mirror images of a compound that cannot be overlayed |
| achiral | an object that lacks handedness |
| chiral | an object that has handedness |
