Choose the most appropriate match :
| List - I (Class of Chemicals) | List - II (Example) | ||
|---|---|---|---|
| (a) | Antifertility drug | (i) | Meprobamate |
| (b) | Antibiotic | (ii) | Alitame |
| (c) | Tranquilizer | (iii) | Norethindrone |

Answer and solution
Answer (b) (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)
Solution
Chemistry ma’am · 2 steps
Name what each compound does in the body, and the four pairs fall into place one by one.
- Know each example. Norethindrone is a synthetic progesterone used in birth control pills. Salvarsan is an arsenic compound that Ehrlich used against syphilis. Meprobamate is a mild tranquilizer for anxiety and tension. Alitame is a sweetener about 2000 times sweeter than cane sugar.
Class (List I) Example (List II) Why it fits (a) Antifertility drug (iii) Norethindrone synthetic progesterone that stops ovulation (b) Antibiotic (iv) Salvarsan arsenic drug that kills the syphilis microbe (c) Tranquilizer (i) Meprobamate relieves anxiety and tension (d) Artificial sweetener (ii) Alitame very sweet, almost no calories - So. The match is (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii). Only option (b) pairs Norethindrone with the antifertility drug, and its other three pairs are also correct.
The idea to keep. For drug-class matching, learn one textbook example per class: Norethindrone for antifertility, Salvarsan as an antibiotic, Meprobamate as a tranquilizer, Alitame as a sweetener.
