The oxidation state of nitrogen in `N_(3)H` isA. `+(1)/(2)`B. `+3`C. `-1`D. `-(1)/(3)`

Answer» Correct Answer - D
The oxidation state of hydrogen is always `+1` except in ionic hydrides (where ON of hydrogen is `-1`). `N_(3)H` (hydrogen acid) is not an ionic compound, hence
`3x + (+1) = 0`
`3x = -1, x = -1//3`
