The N3 molecule would be a radical. Two N3 molecules would immediately react with eachother as soon as they collided, decomposing into three N2
molecules. The N3 molecules would also be very unstable because of the bond strain (being a triangular ring), and also because of the lone pair
repulsion.
You might do some research into the oxidation of sodium azide.
The basic answer is no, it is not possible to isolate N3 as a pure compound, although it could theoretically be possible to make N3 molecules and trap
them into a crystal (of some other compound) at low temperatures. |
