Among the hydrides given below which are reasonably good acids.

$\begin{array}{1 1}(a)\;NH_3\\(b)\;HF\\(c)\;N_3^-\\(d)\;NaH\end{array}$

1 Answer

After donating hydrogen $HN_3$ will change into $N_3^{−}$ , which is a conjugate base and is very stable due to resonance in the structure.
$N_3^-$ having resonance stability.
Hence (c) is the correct answer.
