In which of the following compounds, nitrogen exhibits highest oxidation state?
Options
- AN 2 H 4
- BNH 3
- CN 3 H
- DNH 2 OH
Correct answer
C. N 3 H
Step-by-step solution
N 2 H 4 ⇒ 2 x + 4 + 1 = 0 ⇒ 2 x + 4 = 0 ⇒ x = - 2 NH 3 ⇒ x + 3 + 1 = 0 ⇒ x = - 3 N 3 H ⇒ 3 x + 1 + 1 = 0 ⇒ 3 x + 1 = 0 ⇒ x = - 1 / 3 NH 2 OH ⇒ x + 2 + 1 - 2 + 1 = 0 ⇒ x + 1 = 0 ⇒ x = - 1 Thus, highest oxidation state is -1/3.
