Match each catalyst in List I with the industrial process in List II for which it is used. List I: (A) TiCl3 (B) PdCl2 (C) CuCl2 (D) V2O5 List II: (i) Wacker process (ii) Ziegler-Natta polymerization (iii) Contact process (iv) Deacon's process

1. A-ii, B-iii, C-iv, D-i
2. A-iii, B-i, C-ii, D-iv
3. A-iii, B-ii, C-iv, D-i
4. A-ii, B-i, C-iv, D-iii

Correct answer: A-ii, B-i, C-iv, D-iii

Solution

TiCl3 catalyses Ziegler-Natta polymerization, PdCl2 the Wacker process, CuCl2 Deacon's process, and V2O5 the Contact process, giving A-ii, B-i, C-iv, D-iii.
