Quizplus · Accepted Answer

This is characteristic of a syndiotactic configuration. Atactic configuration would have a random arrangement of substituents, isotactic configuration would have all substituents on the same side of the polymer chain, and stereoirregular is not a recognized term in polymer chemistry.
