WebIn 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 (H 2 O) is a hydride of oxygen, ammonia is a hydride of nitrogen, etc.For inorganic chemists, hydrides refer to compounds and ions in which hydrogen is covalently attached …

WebThe most common sources of the hydride nucleophile are lithium aluminium hydride (LiAlH 4) and sodium borohydride (NaBH 4). Note! The hydride anion is not present during this reaction; rather, these reagents serve as a source of hydride due to the presence of a polar metal-hydrogen bond. Because aluminium is less electronegative than boron, ... luxshare ict nghe an limitid
