Nitrous Oxide NaO

Gas, Laughing. Same as Nitrous Oxide, NaO, used as a dental and surgical anesthetic and to preserve perishable foods Ref Hackh s Diet (1944), 368-R 580-R... 

Resonance is by no means restricted to organic molecules. The following sets of valence-bond structures represent the hybrid structures of nitrate ion, NO30, carbonate ion, CO320, and nitrous oxide, NaO. These are only representative examples. We suggest that you check these structures carefully to verify that each member of a set conforms to the general rules for resonance summarized above. 

Preparation. Sodium azide was first prepd in 1891 by Curtius (Ref 1) by saponification of benzoylazide with an ale or aq soln of NaOH. Wislicenus (Ref 2) prepd NaNj by passing a mixt of NH3 and NaO over molten Na or by treating sodium amide at 150°-250° with nitrous oxide ... 

Nitrogen Monoxid. Nitrous oxid—Laughing gas—Nitrogen-protoxid—NaO—Molecular weight=4A—8p. f/r.=1.527A—Fuses at —100° (—148° F.)—Boils at —87° (—134° F.)—Discovered in 1770 bg Priestley. 

Ammonium Nitrate—Ammonii nitras (U. S.)—(NH,)NOa—80—is prepared by neutralizing HNOa with ammonium hydroxid or carbonate. It crystallizes in flexible, anhydrous, six-sided prisms very soluble in HaO, with considerable diminution of temperature fuses at 150° (309° F.), and decomposes at 210° (410° P.), with formation of nitrous oxid (NHj)NOa = NaO-j-2HaO. If the heat be suddenly applied, or allowed to surpass 250° (482° P.), NHa, NO, and NaO are formed. When fused it is an active oxidant. 

The complex [Ru(NH3)5(NaO)] + is amongst the products of reaction of [Ru(NH8)6(NO)] with hydroxylamine, hydrazine, or ammonia. The nitrous oxide complex is thought to arise from nucleophilic attack at the co-ordinated nitrogen. This type of nucleophilic attack at the ligand is an exact parallel of attack by, for instance, azide or hydrazine at the carbonyl carbon of a metal carbonyl (see Part IV, Chapter 5). 

The aqueous solution chemistry of nitrous acid and nitrites has been extensively studied. Some reduction potentials involving these species are given in Table 11.4 (p. 434) and these form a useful summary of their redox reactions. Nitrites are quantitatively oxidized to nitrate by permanganate and this reaction is used in titrimetric analysis. Nitrites (and HNOa) are readily reduced to NO and NaO with SO2, to H2N2O2 with Sn(II), and to NH3 with HaS. Hydrazinium salts yield azides (p. 432) which can then react with further HNOa ...
