MCQ
Identify the pair of binary corresponds in which nitrogen exhibits the lowest and the highest oxidation state.
  • A
    $\mathrm{NH}_3, \mathrm{NO}_2$
  • ✓
    $\mathrm{N}_3 \mathrm{H}, \mathrm{N}_2 \mathrm{O}_5$
    ​
  • C
    $\mathrm{N}_2, \mathrm{HNO}_3$
    ​
  • D
    $\mathrm{N}_2 \mathrm{O}, \mathrm{N}_2 \mathrm{O}_5$
✓

Answer

Correct option: B.
$\mathrm{N}_3 \mathrm{H}, \mathrm{N}_2 \mathrm{O}_5$
​
Oxidation of nitrogen in $N_3​H$ is $-\frac{1}{3},$ which is the lowest possible.
Oxidation of nitrogen in $N_2​O_5$​ is $+5$ which is the highest possible.
