Question

Match List-I with List-II:

| | List-I (Industrial process) | | List-II (Application) | |---|---|---|---| | (a) | Haber's process | (i) | HNO3\mathrm{HNO_3} synthesis | | (b) | Ostwald's process | (ii) | Aluminium extraction | | (c) | Contact process | (iii) | NH3\mathrm{NH_3} synthesis | | (d) | Hall-Heroult process | (iv) | H2SO4\mathrm{H_2SO_4} synthesis |

Choose the correct answer from the options given below:

Options
  1. a

    (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)

  2. b

    (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)

  3. c

    (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)

    ✓
  4. d

    (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)

Correct Answerc

(a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)

Detailed Solution

Strategy: Identify specific industrial processes and their chemical products.

Step 1: Process Analysis

  • Haber's Process: \ceN2+3H2→2NH3\ce{N2 + 3H2 \to 2NH3} (Ammonia synthesis).
  • Ostwald's Process: \ceNH3→NO→NO2→HNO3\ce{NH3 \to NO \to NO2 \to HNO3} (Nitric acid synthesis).
  • Contact Process: \ceS→SO2→SO3→H2SO4\ce{S \to SO2 \to SO3 \to H2SO4} (Sulphuric acid synthesis).
  • Hall-Heroult Process: (\ceAl2O3)(\ce{Al2O3}) reduction for Aluminium extraction.

Step 2: Matching (a)-(III), (b)-(I), (c)-(IV), (d)-(II).

Answer: (Option) [c] (a)-(III), (b)-(i), (c)-(iv), (d)-(ii)\boxed{\text{Answer: (Option) [c] (a)-(III), (b)-(i), (c)-(iv), (d)-(ii)}}
