प्रश्न

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

पर्याय

  • 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.

उत्तर

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.
