Which azide is explosive?

  • Correct answer
    A
    $\mathrm{Ba}\left(\mathrm{N}_3\right)_2$
  • B
    $\mathrm{NaN}_3$
  • C
    $\mathrm{KN}_3$
  • D
    $\mathrm{Mg}_3 \mathrm{~N}_2$

Solution

Ionic azides are usually much more stable e.g. $\mathrm{KN}_3, \mathrm{NaN}_3$ and $\mathrm{Mg}_3 \mathrm{~N}_2$ than the covalent azides. Covalent azides are used as detonators and explosives e.g. $\mathrm{Ba}\left(\mathrm{N}_3\right)_2$.

Hence, the correct answer is option: 'A'.
