Question

In which of these compounds nitrogen exhibit highest oxidation states?

Answer 1

Nitrogen exhibits highest oxidation state in N3H

N3H

3x + 1 = 0

x = -1/3

NH2OH

x + 3(+1) + (-2) = 0

x = -1

(Option 3 isn't clear but if it is supposed to be N2H4, then x = -2)

NH3

x + 3(+1) = 0

x = -3
