  2. Alcohol (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Alcohol_(chemistry)

    In other less formal contexts, an alcohol is often called with the name of the corresponding alkyl group followed by the word "alcohol", e.g., methyl alcohol, ethyl alcohol. Propyl alcohol may be n-propyl alcohol or isopropyl alcohol, depending on whether the hydroxyl group is bonded to the end or middle carbon on the straight propane chain. As ...

  3. Hydroxy group - Wikipedia

    en.wikipedia.org/wiki/Hydroxy_group

    Sulfuric acid contains two hydroxy groups.. Water, alcohols, carboxylic acids, and many other hydroxy-containing compounds can be readily deprotonated due to a large difference between the electronegativity of oxygen (3.5) and that of hydrogen (2.1).

  4. Hydrogen bond - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_bond

    The general notation for hydrogen bonding is Dn−H···Ac, where the solid line represents a polar covalent bond, and the dotted or dashed line indicates the hydrogen bond. [6] The most frequent donor and acceptor atoms are nitrogen (N), oxygen (O), and fluorine (F), due to their high electronegativity and ability to engage in stronger ...

  5. Non-covalent interaction - Wikipedia

    en.wikipedia.org/wiki/Non-covalent_interaction

    It is not a covalent bond, but instead is classified as a strong non-covalent interaction. It is responsible for why water is a liquid at room temperature and not a gas (given water's low molecular weight). Most commonly, the strength of hydrogen bonds lies between 0–4 kcal/mol, but can sometimes be as strong as 40 kcal/mol [3] In solvents ...

  6. Dehydrogenation - Wikipedia

    en.wikipedia.org/wiki/Dehydrogenation

    In metal manufacturing and repairs, dehydrogenation is a thermal treatment which consists in removing the hydrogen absorbed by an object during an electrochemical or chemical process, performed in a specific oven at a temperature of 180–200 °C (360–390 °F) for a minimum time of 2 hours.

  7. Ammonia borane - Wikipedia

    en.wikipedia.org/wiki/Ammonia_borane

    The B−N distance is 1.58(2) Å. The B−H and NH distances are 1.15 and 0.96 Å, respectively. Its similarity to ethane is tenuous since ammonia borane is a solid and ethane is a gas: their melting points differing by 284 °C. This difference is consistent with the highly polar nature of ammonia borane.

  8. Hydrazine - Wikipedia

    en.wikipedia.org/wiki/Hydrazine

    The NN single bond length is 1.447(2) Å (144.7(2) pm), the N-H distance is 1.015(2) Å, the N-N-H angles are 106(2)° and 112(2)°, the H-N-H angle is 107°. [49] The molecule adopts a gauche conformation with a torsion angle of 91(2)° (dihedral angle between the planes containing the N-N bond and the bisectors of the H-N-H angles).

  9. Bonding in solids - Wikipedia

    en.wikipedia.org/wiki/Bonding_in_solids

    A solid with extensive hydrogen bonding will be considered a molecular solid, yet strong hydrogen bonds can have a significant degree of covalent character. As noted above, covalent and ionic bonds form a continuum between shared and transferred electrons; covalent and weak bonds form a continuum between shared and unshared electrons.
