Medium
Match each of the polymers in Group I with the raw material in Group II from which they are made: P. Polyester, Q. Polyamide, R. Viscose rayon, S. Epoxy resin — I. Ethylene Glycol, II. Adipic acid, III. Cellulose, IV. Bisphenol
- P-I, Q-II, R-III, S-IV
- BP-II, Q-I, R-III, S-IV
- CP-I, Q-II, R-IV, S-III
- DP-III, Q-II, R-IV, S-I
Explanation
Polyester (PET) is made using ethylene glycol as a key monomer (P-I). Polyamide (Nylon 66) uses adipic acid (Q-II). Viscose rayon is regenerated from cellulose (R-III). Epoxy resin is made from bisphenol-A (S-IV).
