Question

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

Answer 1

Correct Answer - D
The species formed after adding a proton to the base is known as conjugate acid of the base and the species formed after losing a proton is known as conjugate base of acid. So,
`underset("Base")(NH_(2)^(-))+H^(+)rarr underset("Conjugate acid")(NH_(3))`
