Assertion: Polyamides are best used as fibres

Question:

Assertion: Polyamides are best used as fibres because of high tensile

strength.

Reason: Strong intermolecular forces (like hydrogen bonding within

polyamides) lead to close packing of chains and increase the

crystalline character, hence, provide high tensile strength to

polymers.
