Match List I with List II
| LIST I | LIST II |
| A. Buna-S | I. Polyamide |
| B. Nylon 6, 6 | II. Homopolymer |
| C. Polythene | III. Terephthalic acid, ethylene glycol |
| D. Terylene | IV. Copolymer |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A-IV, B-I, C-II, D-III
(A) Buna-S — This matches (IV) Copolymer. It is made from two different monomers, 1,3-butadiene and styrene.
(B) Nylon 6,6 — This matches (I) Polyamide. Hexamethylenediamine and adipic acid are joined by amide (–CO–NH–) links.
(C) Polythene — This matches (II) Homopolymer. It is made from a single monomer, ethene.
(D) Terylene — This matches (III) Terephthalic acid, ethylene glycol. It is the polyester formed by heating these two monomers.
Shortcut: (A)-(IV) is true only in Option (3).
