In which substance does nitrogen exhibit the lowest oxidation state?

  • A
    Nitrogen gas
  • Correct answer
    B
    Ammonia
  • C
    Nitrous oxide
  • D
    Nitric oxide

Solution

Nitrous oxide N 2 O
N 2 ⇒2x=0
x=0
N H 3 =x+3( +1 )=0
x=−3
N 2 O⇒2x+1( −2 )=0
x=+1
NO⇒x+1( −2 )=0
x=+2

Hence, the correct answer is option: 'B'.
