Match List I with List II.
| List I | Antimicrobials Names | List II | Names |
| (A) | Narrow spectrum antibiotic | (I) | Furacin |
| (B) | Antiseptic | (II) | Sulphur dioxide |
| (C) | Disinfectants | (III) | Penicillin-G |
| (D) | Broad spectrum antibiotic | (IV) | Chloramphenicol |
Choose the correct answer from the options given below:
• Narrow-spectrum antibiotics target specific bacteria (e.g., Penicillin-G).
• Broad-spectrum antibiotics target a wide range of bacteria (e.g., Chloramphenicol).
• Antiseptics are used for external applications to prevent infections.
• Disinfectants are stronger agents used to sterilize non-living surfaces.
- Narrow Spectrum Antibiotic (A): Penicillin-G is effective against a limited range of bacteria, making it a narrow-spectrum antibiotic. Match: (III).
- Antiseptic (B): Furacin is used for preventing infections in wounds and burns, making it an antiseptic. Match: (I).
- Disinfectants (C): Sulphur dioxide is used as a disinfectant for its antimicrobial properties. Match: (II).
- Broad Spectrum Antibiotic (D): Chloramphenicol is effective against a wide range of bacteria, making it a broad-spectrum antibiotic. Match: (IV).
Final Answer: (1)(A) – III, (B) – I, (C) – II, (D) – IV
What will be the equilibrium constant of the given reaction carried out in a \(5 \,L\) vessel and having equilibrium amounts of \(A_2\) and \(A\) as \(0.5\) mole and \(2 \times 10^{-6}\) mole respectively?
The reaction : \(A_2 \rightleftharpoons 2A\)

Cobalt chloride when dissolved in water forms pink colored complex $X$ which has octahedral geometry. This solution on treating with cone $HCl$ forms deep blue complex, $\underline{Y}$ which has a $\underline{Z}$ geometry $X, Y$ and $Z$, respectively, are
