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

Column I (Catalyst)	Column II (Product)
(A) V2O5	(i) Polyethylene
(B) TiCl4/Al(Me)3	(ii) Ethanol
(C) PdCl2	(iii) H2SO4
(D) Iron Oxide	(iv) NH3

Concept:

(A) V₂O₅ - Preparation of H₂SO₄ in contact process

The contact process is the current method of producing sulfuric acid in the high concentrations needed for industrial processes. Platinum, as a good catalyst, is susceptible to reacting with arsenic hence Vanadium oxide (V₂O₅) is now preferred.

(B) TiCl₄ + Al(Me)₃ - Polyethylene (Ziegler – Natal catalyst used for Fin polymerisation)

Ziegler–Natal catalyst is a catalyst used in the synthesis of polymers of 1-alkenes (alpha-olefins). A typical ZN catalyst system usually contains two parts: a transition metal (Group IV metals, like Ti, Zr, Hf) compound and an organo aluminum compound (co-catalyst). The common examples of ZN catalyst systems include TiCl₄ + Et₃Al and TiCl₃ + AlEt₂Cl.

(C) PdCl₂ - Ethanol formation (Wacker’s Process)

Wacker’s process is the method of preparation of aldehydes and ketones from alkenes. The Wacker Oxidation is an industrial process, which allows the synthesis of ethanol from ethene by palladium-catalyzed oxidation with oxygen. Copper serves as redox cocatalyst.

(D) Iron oxide - NH₃ in (Haber’s Process)

Haber’s Process is an artificial nitrogen fixation process and is the main industrial procedure for the production of ammonia today.

Thus, the correct representation of the catalyst with their products is:
