Question

The conjugate acid of amide ion `(NH_(2)^(-))` is
A. `N_(2)H_(4)`
B. `NH_(2)OH`
C. `NH_(4)^(+)`
D. `NH_(3)`

Answer 1

Correct Answer - D
Whenever a species accepts a proton, it forms a conjugate acid. Thus, to find the conjugated acid of amide ion `(NH_(2)^(-))`, we add `H^(+)` and put one more positive charge (i.e., increase charge by 1),
`H^(+)+underset("Base")(NH_(2)^(+))rarr underset("Acid")(NH_(3))`
