Solution
Chemistry ma’am · 3 steps
Put a face to each drug name first: you will meet all four in the NCERT chapter.
- Know each example. Cimetidine stops acid from being made in the stomach. Alitame is a sweetener made in the lab. Novestrol is a synthetic oestrogen used in birth-control pills. Valium calms anxiety.
Class of drug Example Why it fits (a) Antacid (ii) Cimetidine Blocks histamine at the stomach's H₂ receptors, so less acid is released (b) Artificial sweetener (iv) Alitame About 2000 times sweeter than sucrose and more heat-stable than aspartame (c) Antifertility (i) Novestrol Ethynylestradiol, a synthetic oestrogen found in birth-control pills (d) Tranquilizer (iii) Valium Diazepam, a benzodiazepine that relieves anxiety and stress - Narrow down. Antacid goes with Cimetidine and sweetener with Alitame, which leaves only options (a) and (d). The choice then comes down to Novestrol and Valium.
- So. Novestrol is the antifertility drug and Valium the tranquilizer. The match is (a)-(ii), (b)-(iv), (c)-(i), (d)-(iii), which is option (a).
The idea to keep. For drug-class matching, tie each name to what it does in the body. Cimetidine and ranitidine cut stomach acid, Novestrol and norethindrone prevent pregnancy, Valium and equanil calm the mind.
