Question

Some organic compounds are given in List I and their uses in List II. Choose the correct matching

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

Hint:

Iodoform → antiseptic, DDT → insecticide, CHCl$_3$ → solvent, CH$_2$Cl$_2$ → aerosol

Answer 1

The Correct Option is B

Concept: Applications of important organic compounds
To solve matching-type questions, we must know the common uses of standard organic compounds. ---

Step 1: Identify each compound

• (a) Triiodomethane (CHI$_3$) → commonly called iodoform
• (b) p,p'-DDT → insecticide
• (c) Trichloromethane (CHCl$_3$) → chloroform
• (d) Dichloromethane (CH$_2$Cl$_2$) ---

Step 2: Match uses

• Triiodomethane → antiseptic \Rightarrow (a)-(iii)
• DDT → insecticide \Rightarrow (b)-(iv)
• Chloroform → solvent for alkaloids \Rightarrow (c)-(i)
• Dichloromethane → used as aerosol propellant \Rightarrow (d)-(ii) ---

Step 3: Final matching
\[ (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii) \] --- Final Answer: \[ \boxed{(B)} \]
