Question

The conjugate acid of $\text{N}_{3}^{-}$ (Azide ion) is :

• A. $N{{H}_{3}}$
• B. $H{{N}_{3}}$
• C. $NH_{2}^{-}$
• D. $N_{2}^{-}$

Answer 1

Answer: (B)

$H{{N}_{3}}$

Answer 2

Conjugate acid: The species formed by the addition of proton in a base is called conjugate acid. $\underset{Base}{\mathop{N_{3}^{-}}}\,+{{\underset{\Pr oton}{\mathop{H}}\,}^{+}}\to {{N}_{3}}H$ or $\underset{\text{Conjugate}\,\text{acid}}{\mathop{H{{N}_{3}}}}\,$
