WebMetal hydrides are also known as interstitial hydrides. They are formed when hydrogen molecule reacts with the d- and f-block elements. Metals of group 7, 8, and 9 do not form hydrides. They do conduct heat and electricity but not to the extent of their parent metals. Uses of Hydride. They are used as reducing agents in many chemical industries. WebDiborane is produced by the reaction of lithium hydride with boron trifluoride catalyzed by ether at 25ºC. Diborane is used in rocket propellants and as a reducing agent, as a rubber vulcanizer, as a catalyst for olefin polymerization, as a flame-speed accelerator, and as a doping agent in the manufacture of semiconductor devices.
WebDiborane B 2H 6 has an interesting ring-type molecular structure with peculiar bridged hydrogen bonds. Due to the extremely reactive nature of single borane BH 3 which rap-idly dimerizes into stable B 2H 6, diborane thus represents the simplest stable boron hydride. Although kinetically stable, diborane is an endothermic compound H f=
