  2. Hydride - Wikipedia

    en.wikipedia.org/wiki/Hydride

    The hydride reacts with the weak Bronsted acid releasing H 2. Hydrides such as calcium hydride are used as desiccants, i.e. drying agents, to remove trace water from organic solvents. The hydride reacts with water forming hydrogen and hydroxide salt. The dry solvent can then be distilled or vacuum transferred from the "solvent pot".

  3. Reductions with hydrosilanes - Wikipedia

    en.wikipedia.org/wiki/Reductions_with_hydrosilanes

    Reductions with hydrosilanes are methods used for hydrogenation and hydrogenolysis of organic compounds.The approach is a subset of ionic hydrogenation.In this particular method, the substrate is treated with a hydrosilane and auxiliary reagent, often a strong acid, resulting in formal transfer of hydride from silicon to carbon.

  4. Hydrogen astatide - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_astatide

    Hydrogen astatide, also known as astatine hydride, astatane, astatidohydrogen or hydroastatic acid, is a chemical compound with the chemical formula HAt, consisting of an astatine atom covalently bonded to a hydrogen atom. [4] It thus is a hydrogen halide.

  5. Calcium hydride - Wikipedia

    en.wikipedia.org/wiki/Calcium_hydride

    Calcium hydride is widely used as a desiccant for basic solvents such as amines and pyridine. It is also used to dry alcohols. [2] Despite its convenience, CaH 2 has a few drawbacks: It is insoluble in all solvents with which it does not react vigorously, in contrast to LiAlH 4, thus the speed of its drying action can be slow.

  6. Hydrogen-moderated self-regulating nuclear power module

    en.wikipedia.org/wiki/Hydrogen-moderated_self...

    The loss of neutron moderation due to the chemical decomposition of the uranium hydride will consequently slow—and eventually halt—the reaction. When temperature returns to an acceptable level, the hydrogen will again combine with the uranium metal, forming uranium hydride, restoring moderation and the nuclear reaction will start again.

  7. Transition metal hydride - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_hydride

    A metal hydride can be a thermodynamically a weak acid and a weak H − donor; it could also be strong in one category but not the other or strong in both. The H − strength of a hydride also known as its hydride donor ability or hydricity corresponds to the hydride's Lewis base strength. Not all hydrides are powerful Lewis bases.

  8. Lithium aluminium hydride - Wikipedia

    en.wikipedia.org/wiki/Lithium_aluminium_hydride

    Lithium aluminium hydride also reduces alkyl halides to alkanes. [36] [37] Alkyl iodides react the fastest, followed by alkyl bromides and then alkyl chlorides. Primary halides are the most reactive followed by secondary halides. Tertiary halides react only in certain cases. [38] Lithium aluminium hydride does not reduce simple alkenes or arenes.

  9. Hydrogen anion - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_anion

    The term hydride is probably most often used to describe compounds of hydrogen with other elements in which the hydrogen is in the formal −1 oxidation state. In most such compounds the bonding between the hydrogen and its nearest neighbor is covalent. An example of a hydride is the borohydride anion (BH − 4).
