The reaction that does not produce nitrogen is

Options

  1. Aheating N H 4 2 C r 2 O 7
  2. BN H 3 with excess of C l 2
  3. Cheating of N a N 3
  4. Dheating of N H 4 N O 3

Correct answer

B. N H 3 with excess of C l 2

Step-by-step solution

Normal heating; N H 4 N O 3 → Δ N 2 O + 2 H 2 O but Explosion NH 4 NO 3 → Explosion Δ N 2   +   1 2 O 2   +   2H 2 O N H 3 + 3 C l 2 e x c e s s → N C l 3 + 3 H C l
