Choose the correct option out of the following choices.
Assertion: Polyamides are best used as fibers because of high tensile strength.
Reason: Strong intermolecular forces (like hydrogen bonding with polyamides) lead to close packing of chains and increases the crystalline character, hence provide high tensile strength to polymers.
Answer & explanation
Correct answer: option 2
Polyamides are best used as fibres because of high tensile strength. This is because strong intermolecular forces, such as hydrogen bonds within polyamides, cause chains to be tightly packed together and enhance the crystallinity, giving polymers great tensile strength.
