Match the following lists The correct answer is A B C D

Options

  1. A4 3 2 1
  2. B3 2 1 4
  3. C2 4 5 3
  4. D5 1 4 3

Correct answer

A. 4 3 2 1

Step-by-step solution

Correct matching is Benzene -(4 n+2) electrons Ethylene - Mustard gas Acetaldehyde - Silver mirror Chloroform - Phosgene Benzene has 6 electrons, i.e., it follows Huckel rule (4 n+2) electrons. Ethylene reacts with S ₂ Cl ₂ to give mustard gas (war gas). Acetaldehyde gives positive silver mirror test with Tollen's reagent and chloroform on oxidation gives phosgene (poisonous gas).
