Question

Which of the following fibre can be drawn into very fine fibres that can be woven like any other yarn?
A) Terylene
B) Rayon
C) Acrylic
D) Nylon

Answer 1

Hint: The answer here is based on the concept of physical chemistry which deals with the methods of production of polymers that helps you to find the correct answer.

Complete step – by – step answer:
We have come across the basic concepts of physical chemistry and are familiar with term polymers.
- There are several methods used for the polymer productions and these are the things which we use in our daily life.
- To start with, the basic definition of polymers is that they are the substances consisting of very large molecules which are composed of the repeating units of monomers.
- Monomers are obtained naturally and also some are man made.
- There are also polymers which are obtained naturally that include an example of natural rubber. Thus rubbers are further modified in various forms by man.
Now, in the above question they have asked about the fibres and among the given options all are the fibres but not all can be woven easily like any other yarn (bunch of threads).
Usually polyesters can be woven like yarn and these are the polymers made out of monomer which is basically a terephthalic acid also given as PTA or its ester derivative that is dimethyl terephthalate (DMT) and mono ethylene glycol.
Therefore, the polyester among the above options is terylene.

Therefore correct answer is option A)

Note: While answering this type of questions, focus on the monomer part that gives you a way to answer easily and for this you must be thorough with the monomers used to make some of the basic known polymers which we use in daily lives.
