Question
Which factor imparts crystalline nature to a polymer like nylon?
Solution
Strong intermolecular forces like hydrogen bonding and linear structure lead to close packing of polymer chains that imparts crystalline character.

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
