Question

Nylon 6,6 is not a:
A. Condensation polymer
B. Polyamide
C. Copolymer
D. Homo polymer

Answer 1

Hint Polymer is made up of two words poly and mer which in Greek represents as many parts i.e. poly means many and mer means parts and polymer is a large molecule which consists of a number of repeating units of monomers. Where monomer represented one part i.e. single unit.

Complete answer:
Polymers are generally of three types: Natural polymer, semi-synthetic polymers and artificial or synthetic polymers. Nylon 6,6 is the example of synthetic polymer which is a type of polyamide or polymer. It is synthesized by polycondensation i.e. condensation polymer in which polymers are formed with the help of condensation reactions. In this type of reaction molecules join together by losing small molecules in the form of water or methanol.
Nylon 6,6 is made up of two monomers in which each containing 6 carbon atoms and monomer units are named as hexamethylenediamine and adipic acid hence it is copolymer i.e. made up of more than one type of monomer.
Hence from the above discussion we can say that Nylon 6,6 is polyamide, condensation polymer and copolymer. So it is not a homopolymer i.e. those polymers which are made up of only one kind of monomer.

Thus option D is the correct answer.

Note: Natural polymers are those which we find from plants and animals, semi synthetic are those which are found naturally but need further chemical modifications and synthetic polymers are those which are prepared by man.
