MCQ
The oxidation state of nitrogen is highest in
  • ${N_3}H$
  • B
    $N{H_2}OH$
  • C
    ${N_2}{H_4}$
  • D
    $N{H_3}$

Answer

Correct option: A.
${N_3}H$
(a) $3 \times x + 1\,(1) = 0$

$3x + 1 = 0$

$3x = - 1,\, \Rightarrow x = - \frac{1}{3}\,\,{\rm{in}}\,\,{N_3}H$

$x + 2\,( + 1) + 1\,( - 2) + 1(1) = 0$

$x = - 1\,\,{\rm{in}}\,\,N{H_2}OH$

$x \times 2 + 4\,(1) = 0$$x = - \frac{4}{2} = - 2\,{\rm{in}}\,\,{N_2}{H_4}$

$x + 3\,(1) = 0$$x = - 3\,\,in\,\,N{H_3}$

Hence, highest in ${N_3}H$.
