Options

  1. AA-(ii), B-(i), C-(iv), D-(iii)
  2. BA-(iii), B-(i), C-(iv), D-(ii)
  3. CA-(iii), B-(iv), C-(i), D-(ii)
  4. DA-(i), B-(iii), C-(ii), D-(iv)

Correct answer

B. A-(iii), B-(i), C-(iv), D-(ii)

Step-by-step solution

Zn ²⁺ belongs to Group IV of basic radicals. The group reagent is H₂S gas in the presence of NH₄OH and NH₄Cl . Cu ²⁺ belongs to Group II of basic radicals. The group reagent is H₂S gas in the presence of dilute HCl . Ca ²⁺ belongs to Group V of basic radicals. The group reagent is ( NH₄ )₂ CO₃ in the presence of NH₄OH and NH₄Cl . Fe ³⁺ belongs to Group III of basic radicals. The group reagent is NH₄OH in the presence of NH₄Cl . Thus, the correct matching is A-(iii), B-(i), C-(iv), D-(ii). Answer: A-(iii), B-(i), C-
