  2. Hydrogen polyoxide - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_polyoxide

    Chemical structure of water, the simplest hydrogen polyoxide. Hydrogen polyoxides (also known as oxidanes, oxohydrogens, or oxyhydrogens) are chemical compounds that consist only of hydrogen and oxygen atoms, are bonded exclusively by single bonds (i.e., they are saturated), and are acyclic (have molecular structures containing no cycles or loops).

  3. Boron compounds - Wikipedia

    en.wikipedia.org/wiki/Boron_compounds

    Boranes are chemical compounds of boron and hydrogen, with the generic formula of B x H y. These compounds do not occur in nature. Many of the boranes readily oxidise on contact with air, some violently. The parent member BH 3 is called borane, but it is known only in the gaseous state, and dimerises to form diborane, B 2 H 6. The larger ...

  4. Boron hydride clusters - Wikipedia

    en.wikipedia.org/wiki/Boron_hydride_clusters

    Some higher boranes, especially those with bridging hydrogen atoms, can be deprotonated with a strong base. An example: B 5 H 9 + NaH → Na[B 5 H 8] + H 2. Acidity increases with the size of the borane, with B 10 H 14 having a pK a value of 2.7: [12] B 5 H 9 < B 6 H 10 < B 10 H 14 < B 16 H 20 < B 18 H 22. In general, bridging hydrogen protons ...

  5. Alkyl group - Wikipedia

    en.wikipedia.org/wiki/Alkyl_group

    A cycloalkyl group is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula −C n H 2n−1. [2] Typically an alkyl is a part of a larger molecule. In structural formulae, the symbol R is used to designate a generic (unspecified) alkyl group. The smallest alkyl group is methyl, with the formula −CH 3 ...

  6. Strontium hydride - Wikipedia

    en.wikipedia.org/wiki/Strontium_hydride

    Strontium hydride is an inorganic compound with a chemical formula SrH 2. Reactions ... SrH 2 + 2 H 2 O → 2 H 2 + Sr(OH) 2. See also. Beryllium hydride; Magnesium ...

  7. Structural formula - Wikipedia

    en.wikipedia.org/wiki/Structural_formula

    Skeletal structural formula of Vitamin B 12.Many organic molecules are too complicated to be specified by a molecular formula.. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are connected to one another. [1]

  8. Ternary compound - Wikipedia

    en.wikipedia.org/wiki/Ternary_compound

    In inorganic chemistry and materials chemistry, a ternary compound or ternary phase is a chemical compound containing three different elements.. While some ternary compounds are molecular, e.g. chloroform (HCCl 3), more typically ternary phases refer to extended solids.

  9. Hydride - Wikipedia

    en.wikipedia.org/wiki/Hydride

    C 6 H 5 C(O)CH 3 + KH → C 6 H 5 C(O)CH 2 K + H 2. Typical solvents for such reactions are ethers. Water and other protic solvents cannot serve as a medium for ionic hydrides because the hydride ion is a stronger base than hydroxide and most hydroxyl anions. Hydrogen gas is liberated in a typical acid-base reaction.
