Passage / Comprehension
The utility of polymers in various fields is due to their mechanical properties like tensile strength, elasticity, toughness, etc. These properties mainly depend upon intermolecular forces like van der Waals forces and hydrogen bonding operating in polymer molecules. Polymers have been classified on this basis as e.g.
(i) Elastomers
(ii) Fibres
(iii) Thermoplastics
(iv) Thermosetting
Which of the following have usually a linear structure?
Options:
Answer:
A
Solution:
In thermoplastics linear chain exists. In thermosetting polymers, cross-links exist. Bakelite is an example of thermosetting polymer. Nylon-6, 6 is an example of fibre. (a) is correct while (b), (c) and (d) are incorrect.
