Assertion (A) : Polyamides are best used as fibres because of high tensile strength. Reason (R) : 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.

1.	Assertion (A) : Polyamides are best used as fibres because of high tensile strength. Reason (R) : 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.
Answer» ASSERTION and reason both are correct statements but reason does not explain assertion. Assertion and reason both are correct statements and reason explain the assertion. Both assertion and reason are WRONG statements. Assertion is correct statement and reason is wrong statement. Solution :Assertion and reason both are correct statements and reason explain the assertion. Polyamides are best used as fibres because of high tensile STRENGTH. This is due to strong intermolecular forces (like hydrogen bonding within polyamides) lead to close packing of chains and INCREASES the crystalline character, hence, provide high tensile strength.
