A hydride of nitrogen which is acidic in nature is :

Options

A. `NH_3`
B. `N_3H`
C. `N_2 H_2`
D. `N_(2)H_(4)`

Answer

B

Explanation

Hydrazoic acid `(N_3H)` is a weak acid . Its weak acidic character is due to to the formation of azide ion `(N_3^(-))` after the loss of proton which is more stabilised by resonance as compared to hydrazoic acid itself.
`[N-=N^(+)-N^(-)]^(-) harr[N^(-)-overset(+)(N)-=N]^(-)`
