Question

The conjugate base of $NH_3$ is

• A. $NH^+_4$
• B. $NH_4OH$
• C. $NH_2OH$
• D. $NH^-_2$

Answer 1

Answer: (D)

$NH^-_2$

Answer 2

A conjugate base has one proton less from the acid. If we remove one proton from $NH _{3}$, we get $NH _{2}^{-} .NH _{3} \rightarrow NH _{2}{ }^{-}+ H ^{+} .$
