Chemistry ma’am · 3 steps
Remember what each drug is used for, and the class follows. Start with Furacin and Arsphenamine.
- Match by use. Each drug name points to a medical use you can recall from NCERT. Once you know the use, the class is fixed.
Drug What it is used for Class Furacin applied to wounds and cuts on living tissue antiseptic (iii) Arsphenamine (Salvarsan) Ehrlich's arsenic drug that kills the microbe causing syphilis antibiotic (i) Dimetone blocks histamine in allergies synthetic antihistamine (iv) Valium calms anxiety and stress tranquilizer (ii) - Where options differ. Options (a) and (d) agree on Dimetone and Valium. They differ only in Furacin and Arsphenamine. Furacin is applied on the skin, so it is the antiseptic, and Arsphenamine is the antibiotic.
- So. The match is (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii), which is option (d).
The idea to keep. Group drugs by use. Furacin, dettol and soframicine go on wounds. Salvarsan and penicillin kill microbes. Dimetone, seldane and ranitidine block histamine. Valium, equanil and veronal calm the mind.
