Hydride chemistry
WebMetal hydrides are compounds of one or more metal cations (M+) and one or more hydride anions (H − ). When pressurised, most metals bind strongly with hydrogen, resulting in stable metal hydrides that can be used to store hydrogen conveniently on board vehicles. Examples of metal hydrides are LaNi 5 H 6, MgH 2, and NaAlH 4. WebNitride hydrides are a largely unexplored class of materials with promising applications in solid-state hydrogen fuel cells. Here, we use first-principles calculations to characterize defects and ionic mobility in Sr2LiH2N (SLHN), a nitride hydride that has previously been synthesized but has not yet been evaluated as a hydride conductor. Calculating defect …

In chemistry, a hydride is formally the anion of hydrogen (H ). The term is applied loosely. At one extreme, all compounds containing covalently bound H atoms are called hydrides: water (H2O) is a hydride of oxygen, ammonia is a hydride of nitrogen, etc. For inorganic chemists, hydrides refer to compounds … Meer weergeven Bonds between hydrogen and the other elements range from highly to somewhat covalent. Some hydrides, e.g. boron hydrides, do not conform to classical electron-counting rules and the bonding is described in … Meer weergeven Free hydride anions exist only under extreme conditions and are not invoked for homogeneous solution.

WebHydride shift is a rearrangement of a hydrogen atom in a carbocation to make the intermediate structure more stable. It is generally observed in rearrangement reactions. After shifting a hydrogen atom from one carbon to another, structural isomers of compounds are formed. This rearrangement happens to make carbocation more stable.
