Question
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:
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
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.
