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.

(a)

Interpretation Introduction

Interpretation:

The structures of cis- and trans-polyacetylene are to be drawn.

Concept introduction:

The polymers are made from the polymerisation of monomer units. Polyacetylene is made from polymerization of ethyne molecule. Polyacetylene exist in two geometrical isomers (cis and trans).

(b)

Interpretation Introduction

Interpretation:

An explanation to show that cis- and trans-polyacetylene conduct electricity is to be stated.

Concept introduction:

The double bonds in the structures of cis- and trans-polyacetylene are present at alternative positions. These alternative positions of double bonds indicate that cis- and trans-polyacetylene are conjugated and thereby movement of electrons are possible.

(c)

Interpretation Introduction

Interpretation:

An explanation for the possibility to prepare anisotropic electrical conductivity (unusual behaviour) polyacetylene films is to be stated.

Concept introduction:

Anisotropic electrical conductivity of a polymer refers to the different conductivity of a polymer in different direction. Electrical conductivity, parallel to the layer of a polymer is high as compare to perpendicular to the layer of a polymer.
