Match the catalyst with the process. Which of the following is the correct option?
Column I
- I. $V_2O_5$
- II. $TiCl_4+Al(CH_3)_3$
- III. $PdCl_2$
- IV. Nickel complexes
Column II
- A. The oxidation of ethyne to ethanal
- B. Polymerisation of alkynes
- C. Oxidation of $SO_2$ in the manufacture of $H_2SO_4$
- D. Polymerisation of ethylene
Correct answer: I → C, II → D, III → A, IV → B
Detailed Solution
$V_2O_5$ - oxidation of $SO_2$ in the contact process; $TiCl_4+Al(CH_3)_3$ (Ziegler-Natta) - polymerisation of ethylene; $PdCl_2$ - Wacker oxidation to ethanal; nickel complexes - polymerisation of alkynes.
