NEET 2026 Chemistry Catalytic Roles of Transition Metals Match the Following Question

Type: Match the Following-conceptual-Medium-Class 12

Match List I with List II :

Transition metal/compound/complexCatalytic Role
(A) V₂O₅(I) Preparation of ammonia from N₂/H₂ mixture
(B) Fe(II) Polymerisation of alkynes
(C) PdCl₂(III) Preparation of H₂SO₄ and SO₂
(D) Ni complex(IV) Oxidation of ethyne to ethanal
A

(1) A⁻III, B⁻IV, C⁻I, D⁻II

B

(2) A⁻IV, B⁻I, C⁻III, D⁻II

C

(3) A⁻II, B⁻I, C⁻IV, D⁻III

D

(4) A⁻III, B⁻I, C⁻IV, D⁻II

Correct Answer

Option D

Detailed Explanation

V₂O₅ catalyzes the oxidation of SO₂ into SO₃ in the manufacture of H₂SO₄. Fe acts as a catalyst in the preparation of ammonia from N₂/H₂ mixture. PdCl₂ catalyzes the oxidation of ethyne to ethanal. Ni complex is used in the polymerisation of alkynes.
