Options
- AA-(ii), B-(i), C-(iv), D-(iii)
- BA-(iii), B-(i), C-(iv), D-(ii)
- CA-(iii), B-(iv), C-(i), D-(ii)
- 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-
