Interpretation: The representation of isotactic, syndiotactic and atactic polyacrylonitrile has to be drawn using the monomer given in the problem question.
Concept Introduction:
The monomers in main chain of polymer can be oriented in orderly or disorderly manner. Tacticity refers to the stereoregularity in arrangement of repeating monomeric units in the polymer backbone. Tacticity is of following types,
Isotactic – Side groups/
Syndiotactic - Side groups/functional groups present in alternate manner in the backbone
Atactic - Side groups/functional groups are present in random manner in the backbone
