Answer 1

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.

(b)

Interpretation Introduction

Interpretation:

Draw mechanism of formation of poly(ethylene oxide) from ethylene oxide

Concept introduction:

Polymerization is a reaction when monomer molecules are reacted to form a polymer chain. In acidic conditions the epoxide gets protonated and then nucleophilic attack occurs in the epoxide ring opens to form an alcohol. This acts as weak nucleophile and attacks another protonated epoxide ring to extend the carbon chain forming a polymeric chain.

To draw: To draw a mechanism for formation of poly(ethylene oxide) under acidic conditions

(c)

Interpretation Introduction

Interpretation:
