A substituted ethylene polymer in which the substituents are randomly oriented is called
A)a ditactic polymer.
B)an eutatic polymer.
C)an isotactic polymer.
D)a syndiotatic polymer.
E)an atactic polymer.

Question

Quizplus · Accepted Answer

An atactic polymer is a polymer in which the side groups or substituents are randomly oriented in a polymer chain. The other options refer to polymers with ordered substituent orientations: ditactic polymers have two alternating substituents, eutactic polymers have a specific arrangement of substituents, isotactic polymers have substituents all on the same side of the polymer chain, and syndiotactic polymers have substituents alternating on different sides of the chain.
