Question

Polymerization and the break down of a polymer are two opposite reactions. What role does a water molecule play in both of them?

Answer 1

In the process of polymerization, a chain of similar smaller molecules called monomer join together to create very large molecules called polymer. Through this chemical reaction, water is created as a by-product. In contrast to hydrolysis or breaking down of polymers, a water molecule is used to break the covalent bond that hold the components of a polymer.
