Answer 1

CONCEPT:

Catalysts and their Applications

A catalyst is a substance that speeds up a chemical reaction without being consumed in the process.
Different reactions require specific catalysts to enhance the rate of reaction or achieve desired selectivity.

EXPLANATION:

In the given problem, we need to match the catalysts in List-I with their corresponding reactions or components in List-II:
- A. Haber Process: This is the industrial process to synthesize ammonia (NH₃) from nitrogen (N₂) and hydrogen (H₂). The catalyst used is iron (Fe). Hence, A matches with I.
- B. Wacker Oxidation: This process involves the oxidation of alkenes (e.g., ethylene) to aldehydes or ketones using palladium chloride (PdCl₂) as the catalyst. Hence, B matches with II.
- C. Wilkinson Catalyst: This is a homogeneous catalyst [(PPh₃)₃RhCl] used for hydrogenation reactions in organic chemistry. Hence, C matches with III.
- D. Ziegler Catalyst: This catalyst (a combination of TiCl₄ and Al(CH₃)₃) is used for polymerization of alkenes to produce polyethylene. Hence, D matches with IV.

Correct Answer: Option 3) A-I, B-II, C-III, D-IV
