Match List-I with List-II.

	List-I		List-II
A.	Haber process	I.	Fe catalyst
B.	Wacker oxidation	II.	$\text{PdCl₂}$
C.	Wilkinson catalyst	III.	$\text{[(PPh₃)₃RhCl]}$
D.	Ziegler catalyst	IV.	$\text{TiCl₄ with Al(CH₃)₃}$

Choose the correct answer from the options given below :

The correct answer is A-I, B-II, C-III, D-IV.

Let us analyze each process/catalyst from List-I and match it with the correct chemical formula or catalyst component from List-II:

A. Haber process matches with I (Fe catalyst)
The Haber process is a industrial chemical method used to synthesize ammonia from nitrogen gas and hydrogen gas. The process uses iron ($\text{Fe}$) as a catalyst, along with promoters such as potassium oxide (${\text{K}}_2\text{O}$) and aluminum oxide (${\text{Al}}_2{\text{O}}_3$), to increase the rate of reaction at manageable temperatures.

B. Wacker oxidation matches with II (${\text{PdCl}}_2$)
The Wacker process involves the oxidation of ethylene to acetaldehyde. It utilizes palladium(II) chloride (${\text{PdCl}}_2$) as the primary catalyst in an aqueous solution, along with copper(II) chloride (${\text{CuCl}}_2$) as a co-catalyst to reoxidize the palladium catalyst back to its active state.

C. Wilkinson catalyst matches with III ($\left[{\left({\text{PPh}}_3\right)}_3\text{RhCl}\right]$)
Wilkinson's catalyst is a coordination complex of rhodium, chlorotris(triphenylphosphine)rhodium(I), with the chemical formula:
$\left[{\left({\text{PPh}}_3\right)}_3\text{RhCl}\right]$
It is widely used as a homogeneous catalyst for the hydrogenation of alkenes.

D. Ziegler catalyst matches with IV (${\text{TiCl}}_4\text{with Al}{\left({\text{CH}}_3\right)}_3$)
Ziegler-Natta catalysts are a class of catalysts used in the polymerization of 1-alkenes (such as ethylene and propylene). A classic example of a Ziegler catalyst is a combination of a transition metal halide like titanium tetrachloride (${\text{TiCl}}_4$) and an organometallic compound like trimethylaluminum ($\text{Al}{\left({\text{CH}}_3\right)}_3$) or triethylaluminum ($\text{Al}{\left({\text{C}}_2{\text{H}}_5\right)}_3$).

Thus, matching all the options correctly:
A → I
B → II
C → III
D → IV
