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
Options
Assertion and reason both are correct statement but reason does not explain assertion.
Assertion and reason both are correct statements and reason explains the assertion.
Both assertion and reason are wrong statement.
Assertion is correct statement and reason is wrong statement.
Assertion is wrong statement and reason is correct statement.

Solution
Assertion and reason both are correct statements and reason explains the assertion.
Explanation:
Polyamides like nylons are best-used fibres. They have high tensile strength due to presence of strong intermolecular hydrogen bond.
