Question

Match the catalysts (Column I) with products (Column II).

Column I	Column II
(A) \(\mathrm{V_2O_5}\)	(i) Polyethylene
(B) \(\mathrm{TiCl_4/Al(Me)_3}\)	(ii) ethanal
(C) \(\mathrm{PdCl_2}\)	(iii) \(\mathrm{H_2SO_4}\)
(D) Iron Oxide	(iv) \(\mathrm{NH_3}\)

• A. (A)-(iii); (B)-(i); (C)-(ii); (D)-(iv)
• B. (A)-(ii); (B)-(iii); (C)-(i); (D)-(iv)
• C. (A)-(iii); (B)-(iv); (C)-(i); (D)-(ii)
• D. (A)-(iv); (B)-(iii); (C)-(ii); (D)-(i)

Hint:

Contact process, Ziegler-Natta polymerisation, Wacker process and Haber process use these catalysts respectively.

Answer 1

The Correct Option is A

(A) \(\mathrm{V_2O_5}\) is the catalyst in the Contact process for \(\mathrm{H_2SO_4}\) (oxidation of \(\mathrm{SO_2}\) to \(\mathrm{SO_3}\)): A - (iii).
(B) \(\mathrm{TiCl_4/Al(Me)_3}\) is the Ziegler-Natta catalyst used for polymerisation of ethene to (high density) polyethylene: B - (i).
(C) \(\mathrm{PdCl_2}\) is the catalyst in the Wacker process: \(\mathrm{CH_2{=}CH_2 + \tfrac12 O_2 \rightarrow CH_3CHO}\) (ethanal): C - (ii).
(D) Iron oxide (with promoters, Haber process) gives \(\mathrm{NH_3}\) from \(\mathrm{N_2 + H_2}\): D - (iv).
Matching: (A)-(iii); (B)-(i); (C)-(ii); (D)-(iv), which is option (1).
Answer: (1) (A)-(iii); (B)-(i); (C)-(ii); (D)-(iv)
