Match List-I with List-II.

List-I	List-II
A. Haber process B. Wacker oxidation C. Wilkinson catalyst D. Ziegler catalyst	I. Fe catalyst II. PdCl2 III. [(PPh3)3RhCl] IV. 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.

Here is the step-by-step explanation for matching each process or catalyst from List-I with its corresponding chemical species in List-II:

A. Haber process: This is the industrial process used for the synthesis of ammonia from nitrogen and hydrogen gases. It utilizes a finely divided iron (Fe) catalyst, often promoted with oxides of potassium and aluminum, to increase the reaction rate. Thus, A matches with I.

B. Wacker oxidation: This industrial process oxidizes ethylene to acetaldehyde. The catalytic system key to this reaction is palladium chloride (PdCl₂) in conjunction with copper chloride (CuCl₂). Thus, B matches with II.

C. Wilkinson catalyst: This is a homogeneous catalyst used for the hydrogenation of alkenes. Chemically, it is chloridotris(triphenylphosphine)rhodium(I), represented by the formula [(PPh₃)₃RhCl]. Thus, C matches with III.

D. Ziegler catalyst: Ziegler-Natta catalysts are used in the polymerization of 1-alkenes (such as ethylene and propylene). They typically consist of a transition metal compound, such as titanium tetrachloride (TiCl₄), activated by an organometallic co-catalyst like trimethylaluminum (Al(CH₃)₃). Thus, D matches with IV.
