Hydrides of metals
WebChromium(II) hydride, systematically named chromium dihydride and poly(dihydridochromium) is pale brown solid inorganic compound with the chemical formula (CrH 2) n (also written ([CrH 2]) n or CrH 2). Although it is thermodynamically unstable toward decomposition at ambient temperatures, it is kinetically metastable. Webβ-Hydride elimination is a reaction in which an alkyl group bonded to a metal centre is converted into the corresponding metal-bonded hydride and an alkene. The alkyl must have hydrogens on the β-carbon. For instance butyl groups can undergo this reaction but methyl groups cannot. The metal complex must have an empty (or vacant) site cis to the …

These metals enter into a direct reaction with hydrogen at elevated temperatures (300–700 °C [570–1,300 °F]) to produce hydrides of the general …
WebHydrides of group 15 elements are strong reducing agents. The reducing character of hydrides increases from ammonia to bismuthine due to a decrease in the strength of the E – H bond down the group. Bismuthine is the strongest reducing agent among all the hydrides of group 15 elements. Basic nature: These hydrides are basic in nature.
