Match the catalyst with the process: Catalyst: (i) V2O5 (ii) TiCl4 + Al(CH3)3 (iii) PdCl2 (iv) Nickel complexes Process: (a) The oxidation of ethyne to ethanol (b) Polymerisation of alkynes (c) Oxidation of SO2 in the manufacture of H2SO4 (d) Polymerisation of ethylene Which of the following is the correct option?

1. (i)-(c), (ii)-(a), (iii)-(d), (iv)-(b)
2. (i)-(c), (ii)-(d), (iii)-(a), (iv)-(b)
3. (i)-(a), (ii)-(b), (iii)-(c), (iv)-(d)
4. (i)-(a), (ii)-(c), (iii)-(b), (iv)-(d)

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

Solution

V2O5 is used in the oxidation of SO2 to SO3 in the contact process for H2SO4 manufacture. TiCl4 + Al(CH3)3 is a Ziegler-Natta catalyst for ethylene polymerization. PdCl2 catalyzes the oxidation of ethyne to ethanol, and nickel complexes are used in the polymerization of alkynes.
