Match the catalysts given in List-I with the process catalyzed by them given in List-II

Choose the correct answer from the options given below:

(A)-(II), (B)-(IV), (C)-(I), (D)-(III)

The correct answer is Option (2) → (A)-(II), (B)-(IV), (C)-(I), (D)-(III)

(A) Ni in presence of Hydrogen $\rightarrow$ (II) Vegetable oil to ghee

Finely divided Nickel ($Ni$) acts as a catalyst for the hydrogenation of unsaturated vegetable oils (liquid) to convert them into saturated fats like vanaspati ghee (solid).

(B) Finely divided iron $\rightarrow$ (IV) Haber's process

In the Haber's Process for the industrial synthesis of ammonia ($NH_3$) from nitrogen and hydrogen gases, finely divided iron ($Fe$) is used as the catalyst, often with molybdenum or $Al_2O_3$ as a promoter.

(C) $TiCl_4 + Al(CH_3)_3 \rightarrow$ (I) Ziegler Natta Catalyst

A mixture of a transition metal halide (like $TiCl_4$) and an organometallic compound (like trialkyl aluminium) is known as the Ziegler-Natta Catalyst. It is used for the stereospecific polymerization of alkenes (e.g., making polyethylene).

(D) $Cu_2Cl_2 \rightarrow$ (III) Sandmeyer reaction

Copper(I) chloride ($Cu_2Cl_2$ or $CuCl$) is the classic catalyst used in the Sandmeyer reaction to replace a diazonium group in an aromatic ring with a chlorine atom to form aryl chlorides.
