    The conjugate acid of \[\text{NH}_{2}^{-}\]ion is :

    A)  \[N{{H}_{3}}\]                                 

    B)  \[NH_{4}^{+}\]

    C)  \[{{N}_{2}}{{H}_{4}}\]                                  

    D)  \[N{{H}_{2}}OH\]

    Correct Answer: A

    Solution :

                     According to 3ronsted-Lower theory acid and base, the species formed after accepting a proton is called conjugate acid of that base. So,\[\underset{Base}{\mathop{NH_{2}^{-}}}\,+{{H}^{+}}\xrightarrow{{}}\underset{\text{Conjugate}\,\text{acid}}{\mathop{N{{H}_{3}}}}\,\]Conjugate acid of \[NH_{2}^{-}\] is \[N{{H}_{3}}\]
