Answer

To solve the problem of matching the catalysts from Column I with the products from Column II, we will analyze each catalyst and determine the corresponding product based on known chemical processes.

### Step-by-Step Solution:

1. **Identify the first catalyst (A: V₂O₅)**:
- V₂O₅ (Vanadium pentoxide) is commonly used in the contact process for the production of sulfuric acid (H₂SO₄).
- **Match**: A → (iii) H₂SO₄

2. **Identify the second catalyst (B: TiCl₄/Al(Me)₃)**:
- TiCl₄ in combination with Al(Me)₃ is known as a Ziegler-Natta catalyst, which is used in the polymerization of alkenes to produce polymers such as polyethylene.
- **Match**: B → (i) Polyethylene

3. **Identify the third catalyst (C: PdCl₂)**:
- PdCl₂ (Palladium(II) chloride) is used in the Wacker process, where alkenes are oxidized to form aldehydes or ketones. Ethanal (acetaldehyde) is a common product of this reaction.
- **Match**: C → (ii) Ethanal

4. **Identify the fourth catalyst (D: Iron Oxide)**:
- Iron oxide is used in the Haber process for the synthesis of ammonia (NH₃) from nitrogen and hydrogen gases.
- **Match**: D → (iv) NH₃

### Final Matches:
- A → (iii) H₂SO₄
- B → (i) Polyethylene
- C → (ii) Ethanal
- D → (iv) NH₃

### Summary of Matches:
- A: V₂O₅ → H₂SO₄
- B: TiCl₄/Al(Me)₃ → Polyethylene
- C: PdCl₂ → Ethanal
- D: Iron Oxide → NH₃
