Nitrogen Triiodide: The Complete Synthesis.
The volume increases during this reaction
This reaction is very fast
Very fast reactions with an increase in volume are called explosions.
Sensitivity continued This explosion can be set off by touching nitrogen triiodide with a feather.
This is also the only chemical reaction that can be set off with alpha radiation!
Nitrogen triiodide has an enthalpy of formation of 154.4 kJ/mol
Decomposition This is the equation for the decomposition of nitrogen triiodide
Nitrogen triiodide (s) Nitrogen (g) + Iodine (s) Sensitivity This reaction is very sensitive.
This means the activation energy is very small.
In fact, this reaction has the smallest activation energy for any known reaction.
Nitrogen triiodide (s) Nitrogen (g) + Iodine (s) This high sensitivity is thought to occur due to the large iodine atoms being forced too close together in the molecule.
The chemical formula for nitrogen triiodide is NI3
The material that is usually called "nitrogen triiodide" is prepared by the reaction of iodine with . When this reaction is conducted at low temperatures in anhydrous ammonia, the initial product is NI3·(NH3)5, but this material loses some ammonia upon warming to give the 1:1 NI3·(NH3). This adduct was first reported by in 1812, and its formula was finally determined in 1905 by Silberrad. Its solid state structure consists of chains of -NI2-I-NI2-I-NI2-I-... Ammonia molecules are situated between the chains. When kept cold in the dark and damp with ammonia, NI3·(NH3) is stable. However, the dry material is a contact explosive decomposing as follows:
Explosion of nitrogen triiodide: ..
Nitrogen triiodide, also called nitrogen iodide, more correctly, triiodine nitride to distinguish it from the ion, is the with the formula 3. It is an extremely sensitive : small quantities explode with a gunpowder-like snap when touched even lightly, releasing a purple cloud of iodine vapor. NI3 has a complex structural chemistry that has required relatively heroic efforts to elucidate because of the instability of the derivatives.
Synthesis of Tetramethylammonium Triiodide
Stable NF3 was first made in 1928 by Otto Ruff, a German chemist (d.1939) who probably made more fluorides than anyone else, by electrolysis of a molten mixture of ammonium fluoride and hydrogen fluoride. Another route uses the reaction of ammonia with fluorine/nitrogen mixtures over a copper catalyst.
nitrogen, to very complex ones like protein and DNA.
The synthesis of Nitrogen Triiodide is a very unstable substance that can explode when something comes into contact with it. Otherwise known as "touch powder", check out this informative video.
