Identity the incorrect pair from the following:
  1. (A)Photography - AgBr
  2. (B)Polythene preparation
  3. (C)Haber process - Iron
  4. (D)Wacker process ✓ Correct

Answer: (D)

Solution

Checking each pairing: is light-sensitive and is the active component of photographic film — correct. The Ziegler-Natta catalyst is used to polymerise ethene into high-density polythene — correct. Iron is the catalyst in the Haber process for ammonia synthesis, — correct. The Wacker process oxidises ethylene to acetaldehyde using (with as re-oxidant) as the catalyst, not — this pairing is incorrect.
