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 |
