Chapter 27.2, Problem 3P

Interpretation Introduction

Interpretation:

A segment of polystyrene that contain two head-to-head, two head-to-tail and two tail-to-tail linkages should be drawn.

Concept Introduction:

Polymers:

Monomers combine together to form polymers.  Monomers are the repeating units of small molecules which link together to form polymers and the process is called as polymerization.

Two types of polymers:

• Synthetic and biopolymers.
• DNA is an example for biopolymer and these type of polymers are synthesized by cells.
• Polymers synthesized by scientists are called synthetic polymers and some examples are nylon, polyester etc.

Orientation of monomer units in a polymer can be head-to-head, head-to-tail and tail-to-tail.

Head-to-tail orientation is present in most of the polymers, but some exceptions are there.
