  2. Amino radical - Wikipedia

    en.wikipedia.org/wiki/Amino_radical

    In chemistry, the amino radical, ·NH2, also known as the aminyl or azanyl, is the neutral form of the amide ion (NH2). Aminyl radicals are highly reactive and consequently short-lived, like most radicals; however, they form an important part of nitrogen chemistry. In sufficiently high concentration, amino radicals dimerise to form hydrazine.

  3. Azanide - Wikipedia

    en.wikipedia.org/wiki/Azanide

    Azanide is the IUPAC -sanctioned name for the anion NH2. The term is obscure; derivatives of NH2 are almost invariably referred to as amides, [1][2][3] despite the fact that amide also refers to the organic functional group – C (=O)−NR2. The anion NH2 is the conjugate base of ammonia, so it is formed by the self-ionization of ...

  4. Urea - Wikipedia

    en.wikipedia.org/wiki/Urea

    The structure of the molecule of urea is O=C(−NH 2) 2.The urea molecule is planar when in a solid crystal because of sp 2 hybridization of the N orbitals. [8] [9] It is non-planar with C 2 symmetry when in the gas phase [10] or in aqueous solution, [9] with C–N–H and H–N–H bond angles that are intermediate between the trigonal planar angle of 120° and the tetrahedral angle of 109.5°.

  5. Azane - Wikipedia

    en.wikipedia.org/wiki/Azane

    Chemical structure of ammonia, the simplest azane. Azanes / ˌæzeɪns / are acyclic, saturated hydronitrogens, which means that they consist only of hydrogen and nitrogen atoms and all bonds are single bonds. They are therefore pnictogen hydrides. Because cyclic hydronitrogens are excluded by definition, the azanes comprise a homologous series ...

  6. Amine - Wikipedia

    en.wikipedia.org/wiki/Amine

    Amine. In chemistry, amines (/ ə ˈ m iː n, ˈ æ m iː n /, [1] [2] UK also / ˈ eɪ m iː n / [3]) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group [4] (these may respectively be called alkylamines ...

  7. Ammonium sulfate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_sulfate

    2 NH 3 + H 2 SO 4 → (NH 4) 2 SO 4. A mixture of ammonia gas and water vapor is introduced into a reactor that contains a saturated solution of ammonium sulfate and about 2% to 4% of free sulfuric acid at 60 °C. Concentrated sulfuric acid is added to keep the solution acidic, and to retain its level of free acid.

  8. Ammonium iron(II) sulfate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_iron(II)_sulfate

    Ammonium iron (II) sulfate, or Mohr's salt, is the inorganic compound with the formula (NH 4) 2 SO 4.Fe (SO 4).6H 2 O. Containing two different cations, Fe 2+ and NH+4, it is classified as a double salt of ferrous sulfate and ammonium sulfate. It is a common laboratory reagent because it is readily crystallized, and crystals resist oxidation by ...

  9. Thioureas - Wikipedia

    en.wikipedia.org/wiki/Thioureas

    Thioureas. General chemical structure of thioureas. In organic chemistry, thioureas are members of a family of organosulfur compounds with the formula S=C (NR2)2 and structure R2N−C (=S)−NR2. The parent member of this class of compounds is thiourea (S=C (NH2)2). Substituted thioureas are found in several commercial chemicals.
