The Correct Option is D
Approach Solution - 1
The question asks us to identify the incorrect pair from given pairs related to chemical processes and their associated catalysts or compounds.
- Photography - AgBr: In photography, silver bromide (AgBr) is used in photo-sensitive films and papers because it is sensitive to light and decomposes to form a latent image. This pair is correct.
- Polythene preparation – TiCl4, Al(CH3)3: Titanium tetrachloride (TiCl4) and trimethylaluminium (Al(CH3)3) are used together in the Ziegler-Natta catalyst system for the polymerization of ethylene to produce polyethylene (polythene). This pair is correct.
- Haber process - Iron: The Haber process for ammonia synthesis uses iron as a catalyst. This pair is correct.
- Wacker process – Pt Cl2: The Wacker process is used for the oxidation of ethylene to acetaldehyde. The correct catalyst is actually palladium(II) chloride (PdCl2), not platinum chloride (PtCl2). Therefore, this pair is incorrect.
Thus, the incorrect pair is Wacker process – Pt Cl2.
