Note In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices. (i) Assertion and reason both are correct statement but reason does not explain assertion. (ii) Assertion and reason both are correct statements and reason explains the assertion. (iii) Both assertion and reason are wrong statement. (iv) Assertion is correct statement and reason is wrong statement. (v) Assertion is wrong statement and reason is correct statement. ASSERTION: The stereoisomer that has pendant groups of atoms regularly alternating in positions on both sides of a polymer chain is known as syndiotactic stereoisomer. REASON: Isotactic stereoisomers are more crystalline than atactic. 1. ASSERTION: The strength of polymer chains can be improved by introduction of an aromatic side group. REASON: In Kevlar fibers the aromatic rings cause steric hindrance to rotation within the polymer chain. 2. 3. ASSERTION: Network polymers are thermosetting. REASON: Network polymers have high molecular mass. ASSERTION: Tensile strength of concrete is lower than its compressive strength. REASON: In reinforced concrete, the tension forces are transferred from the steel 4. reinforcement to the concrete through bonding. ASSERTION: Glass transition temperature represents non-crystalline materials. 5. REASON: Glass transition temperature is structure sensitive.
