  2. Linnett double-quartet theory - Wikipedia

    en.wikipedia.org/wiki/Linnett_Double-Quartet_Theory

    (a) The top shows both the dot-and-cross diagram and the simplified diagram of the LDQ structure of the CN radical. The nuclei are as indicated and the electrons are denoted by either dots or crosses, depending on their relative spins. Below is shown the dimerisation reaction of the CN monomer into the cyanogen molecule.

  3. Carbon–nitrogen bond - Wikipedia

    en.wikipedia.org/wiki/Carbon–nitrogen_bond

    A carbon–nitrogen bond is a covalent bond between carbon and nitrogen and is one of the most abundant bonds in organic chemistry and biochemistry. [1] Nitrogen has five valence electrons and in simple amines it is trivalent, with the two remaining electrons forming a lone pair. Through that pair, nitrogen can form an additional bond to ...

  4. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule. [1][2][3] A Lewis structure can be drawn for any covalently bonded ...

  5. Calcium nitride - Wikipedia

    en.wikipedia.org/wiki/Calcium_nitride

    Calcium nitride is formed along with the oxide, CaO, when calcium burns in air. It can be produced by direct reaction of the elements: [3] 3 Ca + N 2 → Ca 3 N 2. It reacts with water or even the moisture in air to give ammonia and calcium hydroxide: [4] Ca 3 N 2 + 6 H 2 O → 3 Ca (OH) 2 + 2 NH 3. Like sodium oxide, calcium nitride absorbs ...

  6. Nitric oxide - Wikipedia

    en.wikipedia.org/wiki/Nitric_oxide

    Nitric oxide (nitrogen oxide or nitrogen monoxide [1]) is a colorless gas with the formula NO.It is one of the principal oxides of nitrogen.Nitric oxide is a free radical: it has an unpaired electron, which is sometimes denoted by a dot in its chemical formula (• N=O or • NO).

  7. Carbon nitride - Wikipedia

    en.wikipedia.org/wiki/Carbon_nitride

    Beta carbon nitride - a solid with a formula β- C3N4, which is predicted to be harder than diamond. Graphitic carbon nitride - g- C3N4, with important catalytic and sensor properties. [2] Dicyanocarbodiimide NC-N=C=N-CN - another C3N4 monomer (was detected in products of photolysis of triazido-s-triazine). [3] C3N5 - a combined triazole and ...

  8. Cyanogen - Wikipedia

    en.wikipedia.org/wiki/Cyanogen

    Cyanogen is the chemical compound with the formula (C N) 2. The simplest stable carbon nitride, it is a colorless and highly toxic gas with a pungent odor. The molecule is a pseudohalogen. Cyanogen molecules consist of two CN groups ‒ analogous to diatomic halogen molecules, such as Cl 2, but far less oxidizing.

  9. Molecular orbital diagram - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital_diagram

    Molecular orbital diagram of dinitrogen. With nitrogen, we see the two molecular orbitals mixing and the energy repulsion. This is the reasoning for the rearrangement from a more familiar diagram. The σ from the 2p is more non-bonding due to mixing, and same with the 2s σ. This also causes a large jump in energy in the 2p σ* orbital.
