Question

Match the following:} Compound \hspace{2cm} Use} (a) Methylene chloride \hspace{0.8cm} (i) Solvent for iodine} (b) Chloroform \hspace{1.8cm} (ii) Manufacture of propellents} (c) Iodoform \hspace{2cm} (iii) Metal cleaning} (d) Carbon tetrachloride \hspace{0.6cm} (iv) Antiseptic

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

Hint:

Iodoform has antiseptic use due to liberation of iodine slowly.

Answer 1

The Correct Option is A

Concept:
Common uses of haloalkanes and haloarenes.
Step 1: Match each compound with known use.
Methylene chloride $(CH_2Cl_2)$ is used in cleaning and degreasing metals. \[ (a)\rightarrow(iii) \] Chloroform $(CHCl_3)$ is used as a solvent for iodine. \[ (b)\rightarrow(i) \] Iodoform $(CHI_3)$ is used as an antiseptic. \[ (c)\rightarrow(iv) \] Carbon tetrachloride $(CCl_4)$ was used in manufacture of propellents and refrigerants. \[ (d)\rightarrow(ii) \]
Step 2: Final matching.
\[ (a)-(iii),\ (b)-(i),\ (c)-(iv),\ (d)-(ii) \]
Hence, correct option is (A).
