In which of the following compounds, nitrogen exhibits highest oxidation state?

N₂H₄

NH₃

N₃H

NH₂OH

Solution

N₃H

straight a right parenthesis space stack straight N subscript 2 with straight x on top stack straight H subscript 4 with plus 1 on top 2 left parenthesis straight x right parenthesis space plus left parenthesis plus 1 right parenthesis 4 space equals space 0 2 straight x space equals space minus 4 straight x equals negative 2 space straight b right parenthesis space straight N with straight x on top stack straight H subscript 3 with plus 1 on top straight x plus left parenthesis plus 1 right parenthesis space 3 space equals space 0 straight x equals negative 3 straight c right parenthesis stack straight N subscript 3 with straight x on top straight H with plus 1 on top space straight x plus left parenthesis plus 1 right parenthesis 3 space equals space 0 straight x equals negative 3 straight d right parenthesis space straight N with straight x on top straight H with plus 1 on top subscript 2 straight O with negative 2 on top straight H with plus 1 on top straight x plus left parenthesis plus 1 right parenthesis 2 space plus left parenthesis negative 2 right parenthesis space plus left parenthesis plus 1 right parenthesis space equals space 0 straight x plus 2 minus 2 plus 1 space equals 0 straight x plus 1 space equals space straight x equals negative 1

Thus, oxidation state of nitrogen is highest in N₃H_.
