The polymer containing strong intermolecular forces, i.e. hydrogen bonding, is
A.Teflon
B.nylon-6,6
C.polystyrene✓ Correct
D.natural rubber
Explanation
Nylon-6, 6 is formed by the condensation of amide group and carbonyl group resulting in the formation of –CONH group. The monomers are adipic acid and hexamethylenediamine. It forms the intermolecular H⁻ bonding with the electronegative O atom and the successive chains. 2 2 2 4 6 2 O O Adipic acid Hexamethylene diamine 2 2 2 4 6 O O 8. Which of the following statements about low density polythene is FALSE ? (a) It is a poor conductor of electricity. (b) Its synthesis dioxygen or a peroxide initiator as a catalyst (c) It is used in the manufacture of buckets, dust-bin
