Question

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

Column I	Column II
(A) $V_2{O}_5$	(i) Polyethylene
(B) $Ti{Cl}_4/Al{\left(Me\right)}_3$	(ii) ethanal
(C) $Pd{Cl}_2$	(iii) $H_2{SO}_4$
(D) Iron Oxide	(iv) ${NH}_3$

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

Answer 1

Answer: (B)

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

$V_2{O}_5$ is used as a catalyst in contact process for $H_{2}S{O}_4$

$TiCl_4/Al(Me)_3 is used as a catalyst in Ziegler Natta salt used as the catalyst for polymerisation of ethane to produce Polyethylene

$PdC{l}_2\to$ used as catalyst for ethanal (Wacker process)

Iron oxide $\to$ is used as a catalyst in Haber's synthesis of ammonia.

Hence, the correct option is $D$
