Match the chemical substances in Column I with type of polymers/type of bonds in Column II. Indicate your answer by darkening the appropriate bubbles of the 4 × 4 matrix given in the ORS.
| Column I | Column II |
|---|---|
| (A) cellulose | (p) natural polymer |
| (B) nylon-6,6 | (q) synthetic polymer |
| (C) protein | (r) amide linkage |
| (D) sucrose | (s) glycoside linkage |
Answer: A → I, A → IV, B → II, B → III, C → I, C → III, D → IV
Solution
(A) Cellulose is a natural polymer (polysaccharide) with glycoside linkages between glucose units. Matches: p, s.
(B) Nylon-6,6 is a synthetic polymer formed by condensation polymerization with amide linkages (-CO-NH-). Matches: q, r.
(C) Proteins are natural polymers (polypeptides) with amide linkages (peptide bonds) between amino acids. Matches: p, r.
(D) Sucrose is a disaccharide with a glycoside linkage between glucose and fructose. It is not a polymer. Matches: s.
