Which of the following represents the conjugate pair of `NH_(3)`?

Options

A. `NH_(2)^(Theta)`
B. `NH_(4)^(o+)`
C. Both (a) and (b)
D. `N^(3-)`

Answer

C

Explanation

`NH_(3) +H_(2)O rarr NH_(4)^(o+) + overset(Theta)OH`
`{:(Base,,C_(A),,),(NH_(3)rarr,NH_(2)^(Theta)+,H^(o+),,),("Acid",C_(B),,,):}`
So `NH_(4)^(o+)` and `NH_(2)^(Theta)` are conjugate pair of `NH_(3)`.
