The given monomers need to be polymerized to the corresponding polymers . The number of monomer units in each polymer is restricted to show with four monomer units. So, draw the structural formula of the polyerms with four units. Concept Introduction: Polymerization : Polymerization is a chemical process in which the very small units combine together to form a very large unit with high molar mass. Monomers: It is the small repeating molecule or unit in the polymerization reaction. Polymers: The large unit formed as the end-product in the polymerization reaction is called the polymer.

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.

Interpretation Introduction

Interpretation:

The given monomers need to be polymerized to the corresponding polymers. The number of monomer units in each polymer is restricted to show with four monomer units. So, draw the structural formula of the polyerms with four units.

Polymerization:

Polymerization is a chemical process in which the very small units combine together to form a very large unit with high molar mass.

Monomers:

It is the small repeating molecule or unit in the polymerization reaction.

Polymers:

The large unit formed as the end-product in the polymerization reaction is called the polymer.

(b)

Interpretation Introduction

Interpretation:

The number of ethylene units (monomer) in a large polyethylene molecule need to be calculated by using the degree of polymerization expression.

Concept Introduction:

Degree of polymerizations:

The degree of polymerization is the simple whole-number ratio of the molar mass of the polymer to the molar mass of a monomeric unit for the homopolymer. The general expression for the degree of polymerization can be represented as follows:

Degree of polymerizations =Molar mass of polymerMolar mass of monomer
