Chapter 12, Problem 3QP

Interpretation Introduction

Interpretation:

The type ofmonomer unit needed to make an electrically conducting organic polymer is to be determined.

Concept introduction:

Polymers are molecules with high molecular masses and are made up of repeating monomeric units. Polymers are the backbone of four major chemical industries, viz., plastics, elastomers, fibers, and paintsandvarnishes.

On the basis of the mode of polymerization, polymers have been classified into two subgroups, which are addition polymers and condensation polymers.

Addition polymers are formed when there is a movement of electrons from multiple bonds into new single bonds between molecules without elimination of small molecule.

Polymers that are formed by elimination of small molecules like ${\text{H}}_2\text{O}$ is condensation polymer.

Polymersconducts electricity because of the presence of delocalized electrons to carry charge throughout the polymer chain and are referred as conducting polymer.
