Stereoisomerism | ||||||||
Tacticity It indicates when they are linked to each other in the same way (for example, from head to tail), but they differ in their spatial arrangement, this really focuses on the 3D arrangement of the groups of side chains. The most prevalent configurations:
| ||||||||
Cis | ||||||||
Atom of H and group CH3 on the same side of the chain | ||||||||
Trans | ||||||||
Átomo H y grupo CH3 en lados opuestos de la cadena | ||||||||
Vinyl | ||||||||
The two carbons left aside recall a radical vinyl | ||||||||
Isotactic polymers | ||||||||
All R groups are on the same side of the chain. | ||||||||
Syndiotactic polymers | ||||||||
Alternating sides of the chain. | ||||||||
Atactic polymers | ||||||||
The R groups are "random" | ||||||||
