Question

Match the catalyst with the process:

| Catalyst | Process | | :--- | :--- | | (i) V2O5V_2O_5 | (a) The oxidation of ethylene to ethanal | | (ii) TiCl4+Al(CH3)3TiCl_4 + Al(CH_3)_3 | (b) Polymerisation of alkynes | | (iii) PdCl2PdCl_2 | (c) Oxidation of SO2SO_2 in the manufacture of H2SO4H_2SO_4 | | (iv) Nickel complexes | (d) Polymerisation of ethylene |

Which of the following is the correct matching of Catalyst & Process?

A

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

B

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

C

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

D

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

Step-by-Step Solution

The correct matches based on NCERT are:

  1. V2O5V_2O_5 (Vanadium(V) oxide): Used in the Contact Process for the oxidation of SO2SO_2 to SO3SO_3 in the manufacture of sulphuric acid (H2SO4H_2SO_4). Matches (c).
  2. TiCl4+Al(CH3)3TiCl_4 + Al(CH_3)_3 (Ziegler-Natta catalyst): Used for the polymerisation of ethylene to manufacture polyethylene (polythene). Matches (d).
  3. PdCl2PdCl_2 (Palladium(II) chloride): Used in the Wacker process for the oxidation of ethylene (ethene) to ethanal (acetaldehyde). Matches (a).
  4. Nickel complexes: Useful in the polymerisation of alkynes and other organic compounds like benzene. Matches (b).

Therefore, the correct sequence is (i)-(c), (ii)-(d), (iii)-(a), (iv)-(b).
