When a brown compound of manganese (A) is treated with HCl, it gives a gas (B). The gas taken in excess, reacts with NH3 to give an explosive compound (C). Identify compounds A, B, and C.

Options

  1. AA = MnO 2 , B = H 2 , C = NH 4 NO 3
  2. BA = Mn 2 O 7 , B = Cl 2 , C = NH 4 ClO 4
  3. CA = MnO 2 , B = Cl 2 , C = NH 4 ClO 4
  4. DA = MnO 2 , B = Cl 2 , C = NCl 3

Correct answer

D. A = MnO 2 , B = Cl 2 , C = NCl 3

Step-by-step solution

Correct Option is : (D) A = MnO 2 , B = Cl 2 , C = NCl 3
