MCQ
A hydride of nitrogen which is acidic is
  • A
    $N{H_3}$
  • B
    ${N_2}{H_2}$
  • ✓
    ${N_3}H$
  • D
    ${N_2}{H_4}$
✓

Answer

Correct option: C.
${N_3}H$
c
(c) Hydrazoic acid ${N_3}H$ is a fairly strong acid which is strong than $C{H_3}COOH$ but weak than mineral acid.

${N_3}H \to {H^ + } + N_3^ - $
