Answer
a) The structure of the polycarbonate chain formed from the given reaction is written below.
b) This reaction is condensation polymerization.
Work Step by Step
Look at the below reaction to see how the polycarbonate is formed by condensation reaction where one H from OH group of bisphenol A and one Cl group of phosgene is eliminated and the remaining part of bisphenol A and phosgene are added together to form the dimer and the polymerization continues to form the polycarbonate.
