In the following question, a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices:.

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

Reason: Strong intermolecular forces (like hydrogen bonding within polyamides) lead to the close packing of chains and increase the crystalline character; hence, they provide high tensile strength to polymers.

(i) Assertion and reason both are correct statements, but reason does not explain the assertion.

(ii) Assertion and reason both are correct statements, and reason explain the assertion.

(iii) Both assertion and reason are the wrong statements.

(iv) The assertion is correct statement and reason is the wrong statement.

(v) The assertion is the wrong statement and reason is the correct statement.

Answers (1)

The answer is option (ii). Polyamides are the best-used fibres because they have high tensile strength. They have closely packed chains and an increased crystalline character due to the presence of strong intermolecular forces like hydrogen bonding.
