Assertion: Polyamides are best used as fibres

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.

(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.

Solution:
