  2. Nitrogen dioxide - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_dioxide

    The lone electron in NO 2 also means that this compound is a free radical, so the formula for nitrogen dioxide is often written as • NO 2. The reddish-brown color is a consequence of preferential absorption of light in the blue region of the spectrum (400–500 nm), although the absorption extends throughout the visible (at shorter ...

  3. NOx - Wikipedia

    en.wikipedia.org/wiki/NOx

    In atmospheric chemistry, NO x is shorthand for nitric oxide (NO) and nitrogen dioxide (NO 2), the nitrogen oxides that are most relevant for air pollution. [1] [2] These gases contribute to the formation of smog and acid rain, as well as affecting tropospheric ozone.

  4. Nitrogen oxide - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_oxide

    In atmospheric chemistry: NO x (or NOx) refers to the sum of NO and NO 2. [1] [2] NO y (or NOy) refers to the sum of NO x and all oxidized atmospheric odd-nitrogen species (e.g. the sum of NO x, HNO 3, HNO 2, etc.) NO z (or NOz) = NO y − NO x; Mixed Oxides of Nitrogen ("MON"): solutions of nitric oxide in dinitrogen tetroxide/nitrogen dioxide.

  5. Nitrous oxide - Wikipedia

    en.wikipedia.org/wiki/Nitrous_oxide

    Nitrous oxide (dinitrogen oxide or dinitrogen monoxide), commonly known as laughing gas, nitrous, or factitious air, among others, [4] is a chemical compound, an oxide of nitrogen with the formula N 2 O. At room temperature, it is a colourless non-flammable gas, and has a slightly sweet scent and taste. [4]

  6. Nitro compound - Wikipedia

    en.wikipedia.org/wiki/Nitro_compound

    The structure of an organic nitro compound. In organic chemistry, nitro compounds are organic compounds that contain one or more nitro functional groups (−NO 2).The nitro group is one of the most common explosophores (functional group that makes a compound explosive) used globally.

  7. Nitrous acid - Wikipedia

    en.wikipedia.org/wiki/Nitrous_acid

    Nitrous acid (molecular formula H N O 2) is a weak and monoprotic acid known only in solution, in the gas phase, and in the form of nitrite (NO − 2) salts. [3] It was discovered by Carl Wilhelm Scheele, who called it "phlogisticated acid of niter".

  8. Dinitrogen tetroxide - Wikipedia

    en.wikipedia.org/wiki/Dinitrogen_tetroxide

    Most of the water is condensed out, and the gases are further cooled; the nitric oxide that was produced is oxidized to nitrogen dioxide, which is then dimerized into nitrogen tetroxide: 2 NO + O 2 → 2 NO 2 2 NO 2 ⇌ N 2 O 4. and the remainder of the water is removed as nitric acid. The gas is essentially pure nitrogen dioxide, which is ...

  9. N-Methylmorpholine N-oxide - Wikipedia

    en.wikipedia.org/wiki/N-Methylmorpholine_N-oxide

    N-Methylmorpholine N-oxide (more correctly 4-methylmorpholine 4-oxide), NMO or NMMO is an organic compound.This heterocyclic amine oxide and morpholine derivative is used in organic chemistry as a co-oxidant and sacrificial catalyst in oxidation reactions for instance in osmium tetroxide oxidations and the Sharpless asymmetric dihydroxylation or oxidations with TPAP.
