Hydrogen telluride is the inorganic compound with the formula H 2 Te.A hydrogen chalcogenide and the simplest hydride of tellurium, it is a colorless gas.Although unstable in ambient air, the gas can exist long enough to be readily detected by the odour of rotting garlic at extremely low concentrations; or by the revolting odour of rotting leeks at somewhat higher concentrations.
The −2 oxidation state is exhibited in binary compounds with many metals, such as zinc telluride, ZnTe, produced by heating tellurium with zinc. [2] Decomposition of ZnTe with hydrochloric acid yields hydrogen telluride (H 2 Te), a highly unstable analogue of the other chalcogen hydrides, H 2 O, H 2 S and H 2 Se:
The telluride ion is the anion Te 2− and its derivatives. It is analogous to the other chalcogenide anions, the lighter O 2−, S 2−, and Se 2−, and the heavier Po 2−. [1] In principle, Te 2− is formed by the two-e − reduction of tellurium. The redox potential is −1.14 V. [2] Te(s) + 2 e − ↔ Te 2−
A hydrotelluride or tellanide is an ion or a chemical compound containing the [HTe] − anion which has a hydrogen atom connected to a tellurium atom. HTe is a pseudohalogen . Organic compounds containing the -TeH group are called tellurols .
Binary hydrogen compounds in group 1 are the ionic hydrides (also called saline hydrides) wherein hydrogen is bound electrostatically. Because hydrogen is located somewhat centrally in an electronegative sense, it is necessary for the counterion to be exceptionally electropositive for the hydride to possibly be accurately described as truly behaving ionic.
After a Thursday night premiere at Telluride’s Backlot venue (as a double feature alongside the official bow of 1974’s restored “Tarpon”), it screens again Friday, Sept. 1, at 6:30 p.m. at ...
It was sold nationwide by a New Jersey firm.
Telluric acid, or more accurately orthotelluric acid, is a chemical compound with the formula Te(OH) 6, often written as H 6 TeO 6.It is a white crystalline solid made up of octahedral Te(OH) 6 molecules which persist in aqueous solution. [3]
