Lithium reacts with hydrogen azide to produce

A

`Li_(3)N`

B

`LiN_(2)`

C

`LiN_(3)`

D

`Li_(3)N_(2)`

Text Solution

Verified by Experts

The correct Answer is:
3
Hydrogen azide `HN_(3)` (formerly called hydrazoic acid)dissociates slightly in aqueous solution `(pK_(a)~=5)` .It behaves as a week acid (of similar strength to acetic acid). It reacts with electropositive metals, forming salts called azides, but unlike other acid + metal reactions, no hydrogen is evolved:
`6HN_(3)+4Lirarr4LiN_(3)rarrunderset("Lithium azide")(4LiN_(3))+2NH_(3)+2N_(2)`
