3. (a)
4. (b) It is acetyl salicylic acid i.e., aspirin, analgesic and antipyretic.
5. (a) Whiteware possesses good strength, translucency, and low
porosity.
6. (b)
7. (c) Glyceryl dinitrate is not used as fixative in perfumes.
8. (d) Drugs that mimic the natural messenger by switching on the
receptor are called agonists. While drugs that binds to the receptor
site and inhibit its natural function are called antagonists.
9. (d) The mixture of chloroxylenol and terpenol is dettol which is used
as antiseptic.
10. (c) We know that N-acetyl-para-aminophenol (or paracetamol) is an
antipyretic which can also be used as an analgesic to relieve pain.
11. (a)
12. (a) Benzalkonium chloride, also known as alkyldimethyl-
benzylammonium chloride is nitrogenous cationic surface active
agent belonging to the quaternary ammonium group. It is used as
antiseptic.
13. (d) Bacteriostatic drugs inhibit the growth of organism while
bactericidal drugs kill the microorganisms.
14. (c) Narrow spectrum antibiotics are effective against Gram–positive or
