When a molecule or polyatomic ion has only one central atom, the molecular structure completely describes the shape of the molecule. The structure near the absorption edge is quite complex and has approximately the same shape irrespective of the polarization: i.e., the broad double peak in the region 8–9 eV (labeled A in Fig. We have 3 Nitrogens. We have a central Nitrogen double-bonded to two separate Nitrogens (completing the central atom’s octet). The sodium azide required for automobile air bags is made by the reaction of sodium metal with dinitrogen monoxide in liquid ammonia: 3 N 2 O(g) + 4 Na(s) + NH 3 ( ℓ ) → NaN 3 (s) + 3 NaOH(s) + 2 N 2 (g) (a) You have 65.0 g of sodium, a 35.0-L flask containing N 2 O gas with a pressure of 2.12 atm at 23 °C, and excess ammonia. Nitrogen is in group 5, also called 15, on the periodic table. Answer the questions in the table below about the shape of the azide (N3). [10 pts] (2) What are the all possible resonance structures for each of the molecular structures? You should take formal charges into account with the Lewis structure for N3- to find the best structure for the molecule. It is a compound of nitrogen and hydrogen, and is therefore a pnictogen hydride.It was first isolated in 1890 by Theodor Curtius. Metal azides, consisting of a metal atom and an azide molecule, have attracted considerable attention because of their industrial applications as primary explosives, as gas generators, and even as monolayer crystal materials.
