Options

  1. A1 - (iii), 2 - (iv), 3 - (i), 4 - (ii)
  2. B1 - (i), 2 - (ii), 3 - (iii), 4 - (iv)
  3. C1 - (i), 2 - (iii), 3 - (ii), 4 - (iv)
  4. D1 - (iii), 2 - (i), 3 - (iv), 4 - (ii)

Correct answer

A. 1 - (iii), 2 - (iv), 3 - (i), 4 - (ii)

Step-by-step solution

(1) V ₂ O ₅ -(iii) Oxidation of SO ₂ in the manufacture of H ₂ SO ₄ by contact process. (2) TiCl ₄+ Al ( CH ₃ )₃- (Ziegler-Natta catalyst)- (iv) Polymerisation of ethylene. (3) PdCl ₂- (i) Oxidation of ethyne to ethanal. (4) Nickel complexes-(ii) Polymerisation of alkynes. Thus, the correct match is (1) (iii), (2) (iv), (3) (i), (4) (ii)
