(a)
Interpretation:
Syndiotactic poly (vinyl chloride) segments need to be drawn.
Concept introduction:
If the polymer formed has chiral centers then with the relative configuration of the chiral centers the
(b)
Interpretation:
Isotactic polystyrene segments need to be drawn.
Concept introduction:
If the polymer formed has chiral centers then with the relative configuration of the chiral centers the polymers can be classified as isotactic, Syndiotactic or atactic. When monosubstituted ethylenes are used as monomer the polymer formed has huge number of chiral centers. Isotactic means all the chiral center has the same configuration. Syndiotactic means the chiral centers has alternating configuration. Atactic means the chiral centers are in random arrangement.
