  2. Hydrazine - Wikipedia

    en.wikipedia.org/wiki/Hydrazine

    Hydrazine is an inorganic compound with the chemical formula N 2 H 4.It is a simple pnictogen hydride, and is a colourless flammable liquid with an ammonia-like odour.Hydrazine is highly hazardous unless handled in solution as, for example, hydrazine hydrate (N 2 H 4 ·xH 2 O).

  3. Hydrazines - Wikipedia

    en.wikipedia.org/wiki/Hydrazines

    Hydrazines (R 2 N−NR 2) are a class of chemical compounds with two nitrogen atoms linked via a covalent bond and which carry from one up to four alkyl or aryl substituents. . Hydrazines can be considered as derivatives of the inorganic hydrazine (H 2 N−NH 2), in which one or more hydrogen atoms have been replaced by hydrocarbon grou

  4. Molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Molecular_geometry

    Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It includes the general shape of the molecule as well as bond lengths , bond angles , torsional angles and any other geometrical parameters that determine the position of each atom.

  5. Diimide - Wikipedia

    en.wikipedia.org/wiki/Diimide

    Diimide decomposes readily. Even at low temperatures, the more stable trans isomer rapidly undergoes various disproportionation reactions, primarily forming hydrazine and nitrogen gas: [5] 2 HN=NH → H 2 N−NH 2 + N 2. Because of this competing decomposition reaction, reductions with diimide typically require a large excess of the precursor ...

  6. Hydrazone - Wikipedia

    en.wikipedia.org/wiki/Hydrazone

    When derived from hydrazine itself, hydrazones condense with a second equivalent of a carbonyl to give azines: [10] R 2 C=N−NH 2 + R 2 C=O → R 2 C=N−N=CR 2 + H 2 O. Hydrazones are intermediates in the Wolff–Kishner reduction. Hydrazones are reactants in hydrazone iodination, the Shapiro reaction, and the Bamford–Stevens reaction to ...

  9. Dimethylhydrazine - Wikipedia

    en.wikipedia.org/wiki/Dimethylhydrazine

    Dimethylhydrazine is the name of two compounds with the molecular formula C 2 H 8 N 2. These are: unsymmetrical dimethylhydrazine (1,1-dimethylhydrazine), with both methyl groups bonded to the same nitrogen atom; symmetrical dimethylhydrazine (1,2-dimethylhydrazine), with one methyl group bonded to each of the two nitrogen atoms
