NEET 2026 — Chemistry solution

NEET2026Chemistry

Match List I with List II :

List-I (Transition metal/Compound/complex)	List-II (Catalytic Role)
A. V $_{2}$ O $_{5}$	I. Preparation of ammonia from N $_{2}$ /H $_{2}$ mixture
B. Fe	II. Polymerisation of alkynes
C. PdCl $_{2}$	III. Preparation of H $_{2}$ SO $_{4}$ from SO $_{2}$
D. Ni complex	IV. Oxidation of ethyne to ethanal

Choose the correct answer from the options given below :

Solution

V $_{2}$ O $_{5}$ is the catalyst in the Contact process for the preparation of H $_{2}$ SO $_{4}$ from SO $_{2}$ → III.

Fe is the catalyst in the Haber process for the synthesis of NH $_{3}$ from N $_{2}$ and H $_{2}$ → I.

PdCl $_{2}$ catalyses the oxidation of ethyne to ethanal (Wacker process) → IV.

Ni complex catalysts are used for the polymerisation of alkynes → II.

So A-III, B-I, C-IV, D-II.
