Lithium hydride is an inorganic compound with the formula Li H. This alkali metal hydride is a colorless solid, although commercial samples are grey. Characteristic of a salt-like (ionic) hydride , it has a high melting point, and it is not soluble but reactive with all protic organic solvents .
Lithium aluminium hydride, commonly abbreviated to LAH, is an inorganic compound with the chemical formula Li[Al H 4] or LiAlH 4. It is a white solid, discovered by Finholt, Bond and Schlesinger in 1947. [4] This compound is used as a reducing agent in organic synthesis, especially for the reduction of esters, carboxylic acids, and amides.
Lithium is a highly reactive alkali metal that is widely used in various industrial applications due to its unique properties. Lithium compounds are formed by combining lithium with other elements, such as oxygen, sulfur, and chlorine, to form different chemical compounds.
Some elements and compounds can be both reducing or oxidizing agents. Hydrogen gas is a reducing agent when it reacts with non-metals and an oxidizing agent when it reacts with metals. 2 Li (s) + H 2(g) → 2 LiH (s) [ a ]
A polyhydride or superhydride is a compound that contains an abnormally large amount of hydrogen. This can be described as high hydrogen stoichiometry. Examples include iron pentahydride FeH 5, LiH 6, and LiH 7. By contrast, the more well known lithium hydride only has one hydrogen atom. [1] Polyhydrides are only known to be stable under high ...
Names Preferred IUPAC name. Lithium hydrogen carbonate. Identifiers ... Lithium bicarbonate (LiHCO 3) is a compound of lithium, hydrogen, carbon and oxygen. [1] See also.
Lithium hydride reacts with graphite at 400°C forming lithium carbide. 2 LiH + 4 C → Li 2 C 2 + C 2 H 2. Also Li 2 C 2 can be formed when organometallic compound n-butyllithium reacts with acetylene in THF or Et 2 O used as a solvent, reaction is rapid and highly exothermic. C 2 H 2 + 2 CH 3 CH 2 CH 2 CH 2 Li → Li 2 C 2 + 2 CH 3 CH 2 CH 2 CH 3
Lithium hydroxide is an inorganic compound with the formula LiOH. It can exist as anhydrous or hydrated, and both forms are white hygroscopic solids. They are soluble in water and slightly soluble in ethanol. Both are available commercially. While classified as a strong base, lithium hydroxide is the weakest known alkali metal hydroxide.
