Question

Match the compounds of List-I with their effects in List-II

Codes:

• A. a – i, b – ii, c – iii, d – iv
• B. a - iv, b - iii, c - i, d - ii
• C. a – i, b – iii, c – iv, d – ii
• D. a – iv, b – iii, c – ii, d - i

Hint:

Questions on "Chemistry in Everyday Life" are often based on direct memorization. Creating a table or flashcards linking common drugs/chemicals to their specific uses (e.g., antibiotic, antimalarial, anesthetic) or associated diseases is an effective study strategy.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
This requires factual knowledge linking common medicinal chemistry compounds and biochemical hormones with the specific diseases or physiological conditions they are intended to treat or affect.
Step 2: Key Formula or Approach:
Rely on standard memory recall of drug classifications from the "Chemistry in Everyday Life" curriculum. Match the drug to its therapeutic action.
Step 3: Detailed Explanation:
(a) Chloramphenicol: This is a potent, broad-spectrum antibiotic historically famous for its high effectiveness in the specific treatment of severe typhoid fever. (a $\rightarrow$ iv)
(b) Thyroxine: This is the main iodine-containing hormone produced by the thyroid gland. A dietary deficiency of iodine reduces its production, leading to the enlargement of the thyroid, a condition known as goiter. (b $\rightarrow$ iii)
(c) Chloroquine: An essential synthetic antimalarial medication widely utilized for the treatment and prophylaxis of malaria. (c $\rightarrow$ i)
(d) Chloroform ($CHCl_3$): Historically, its vapors were widely utilized as a general anesthetic in surgery, though its high toxicity has led to its replacement by safer alternatives today. (d $\rightarrow$ ii)
Step 4: Final Answer:
The matching sequence is a-iv, b-iii, c-i, d-ii, which aligns with option (B).
