Chapter E, Problem 5PP

Interpretation Introduction

Interpretation:

The structure of Lexan is to be determined, using given information.

Concept introduction:

>

A polymer is a large molecule or macromolecule composed of many repeated subunits.

>

Polymerization is a process of reacting monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks.

>

Lexan is formed when Bisphenol A reacts with phosgene. During this reaction, there is the loss of one $\text{HCl}$ molecule.

>

It is a type of step-growth polymerisation reaction, in which ${\text{Cl}}^{-}$ is eliminated every time the monomer reacts.
