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

The molecular forces of attraction are the weakest in

Options:

Answer:
A
Solution:

Question Explanation:

The question asks to identify the type of polymer that possesses the weakest intermolecular forces of attraction.

Concept :

This question is based on intermolecular forces in polymers and classification of polymers. Solution:

Elastomers are polymers that exhibit high elasticity. This property is due to the very weak intermolecular forces of attraction (van der Waals forces) between their polymer chains. 

In contrast, fibers have strong intermolecular forces (hydrogen bonds and dipole-dipole interactions), and thermoplastics have stronger forces than elastomers. Thermosetting polymers have strong covalent bonds creating a rigid 3D network, which are the strongest forces.

Final Answer:

The correct option is (A)
