Q4. Polymer configuration is the part of the structure of a molecule that cannot be changed except by the breaking and reforming of primary bonds ( 15pts). a) Describe and draw the following types of polymer configurations: isotactic configuration, syndiotactic configuration, and atactic configuration. Draw a 10 carbon long linear chain and denote side groups with the letter " R " for each example (6 pts). b) Hypothesize whether isotactic or atactic configurations will have a higher affinity of crystallization and explain why (4 pts). c) Would a ten-carbon linear chain with one phenyl group side chain or one methyl group side chain have a higher glass transition temperature and explain why (5 pts)
