The mean Se–O bond distances are 1.709(2) and 1.657(2) Å, respectively, as de H2Se can also be prepared by means of different methods based on the in situ generation in aqueous solution using boron hydride, Marsh test and Devarda's alloy. T. Zane Davis, Jeffery O. *Please select more than one item to compare The structure and hydrogen bonding of the hydrated selenite, SeO3(2-), and selenate, SeO4(2-), ions have been studied in aqueous solution by large angle X-ray scattering (LAXS), EXAFS and double difference infrared (DDIR) spectroscopy. Given names, write formulas; given formulas, write names. Relevance. Three basic types of hydrides—saline (ionic), metallic, and covalent—may be distinguished on the basis of type of chemical bond involved. Selenite is metabolized in red blood cells to hydrogen selenide (Gasiewicz and Smith, 1978).Sequential methylation reactions result in the formation of monomethyl selenide, dimethyl selenide, and trimethyl selenide (Kajander et al., 1991; Itoh and Suzuki, 1997). HPO 4 2− Hydrogen phosphate . According to the Sonoda method, H2Se is generated from the reaction of H2O and CO on Se in the presence of Et3N.
