What name is given to a polymer where all of the substituents (i.e., the R groups) are in the same relative orientation (i.e., on the same side of the polymer chain)?
A) Siamese
B) Atactic
C) Siamo
D) Isotactic
E) Syndiotactic

Question

This type of polymer is called isotactic. In an isotactic polymer, all of the R groups are on the same side of the polymer chain, leading to a regular, orderly structure. This is in contrast to atactic and syndiotactic polymers, where the R groups are randomly or alternately positioned, respectively. The term "Siamese" and "Siamo" are not used in polymer science.
